The radio transmitters to catch a voice.
- It can be installed in any places to keep watch, supervise or connections by which unnecessary worries can be eliminated. When emergency, you are protected from danger or damage. For the other purposes such as infants' surveillance, trespass prevention and the surveillance of the wandering old man dementia and directions on works to perform easily are available. Since it palm size, it is no problem to carry.
- It is a transmitter to catch minute sound. It is very useful for security business, investigation and a detective. This transmitter can catch any minute sound of which every one can hear at the place where it is installed. As well as the sound made by a man moves and if it is a quiet place, the sound of a wall clock hanged at the opposite side against the corner where the transmitter is installed in a room can be clearly heard. In this case, a receiver must be used an exclusive one for the transmitter and if conventional receiver sold in the market is used, it is difficult to hear the sound clearly due to a noise made by the conventional receiver and the available distance is very short.
- UHF band (approx. 320 Mhz) and (approx. 400 Mhz) which are Narrow deviation frequency modulation electric wave are used. Six channels of A: (398.605Mhz) B: (399.455Mhz) and C: (399.455Mhz) D: (320. 235Mhz) E: (320. 675Mhz) F: (321. 135Mhz) channels are always prepared. These waves are available with very little noise and interference and running cost for waves makes very low. Three channels of A. B. C. are available for export.
For the scramble transmitter (SCR-100T) , an exclusive receiver must be used. No conventional receiver sold in the market is available with the transmitter. It is system that 4 kinds carrier (dispatch frequency) is converted into short which is 20 times in one second. The exclusive receiver is restore as it automatically traces to the carrier. Due to a difference on the order of repetition, the exclusive receiver (SCR-100R) is pair with the transmitter in use (all of six kinds of H. I. J. K. L. M.). For ALC (Automatic Loudness Control) is built in the receiver, it can be heard big sound and minute sound in the same level and it doesn't crack even on big voice. The available distance of the wave is about 200 meters on flat ground. If Yagi antenna is used with the receiver, the distance will be extended to about 300 meters. The battery life (lithium battery CR-12600 SE) is 5 days in use continuously. Also, alkali dry cell No.5 batteries (2 pcs) are useful but, the battery life is 2-3 days. If the battery adapter (AD-L) is used, battery life is to be extended to one month.
- The scramble transmitter (SCR-100TA) which is available in connection with a electric light line directly can be used semi permanently once it is installed because of no battery is used. It is very small that enable to place in a wall outlet or some electric apparatus in behind of sight. An exclusive receiver must be used due to a difference on repetition of carrier. (All of six kinds of H. I. J. K. L. M. are available).
Since a remote control formula scramble transmitter (SCR-200T) is a remote control system, it does not always send an electric wave. If the switch of a remote control formula scramble receiver is put in only when required, dispatch of an electric wave will be begun. Since an electric wave is not always sent, it is asked to others, or a possibility of being discovered with a discovery vessel etc. becomes closely that there is nothing. An external video transmitter, an external video camera, etc. are interlocked, and the semiconductor switch circuit which can be connected and cut is included. One lithium battery (CR-2) is used. Although battery lives are about one day and a half if it is made to operate continuously, since it stopped to 1/20 of a state of operation, it will have consumption current of an instruction waiting state about 30 days of continuation. If it is hearing of about 1 hour per day, it will have 20 days. If U1 battery adapter (AD-T) of a dry cell is used when using for a long period of time, it will last long 10 more or more times. That is, even if it uses day for 3 hours per without exchanging a battery, it can use for three months. The form of an electric wave is the same as that of SCR-100T. It cannot be heard that it is not the receiver (SCR-200R) which became the pair by the difference in the order of a repetition of a career (being all six kind H.I.J.K L.M). Since ALC (automatic volume adjustment circuit) is included, it can be heard on the level same from a faint sound to a loud sound. It is not distorted to a loud sound (voice), either, or stripes are not carried out. The notification distance of an electric wave is about about 300m with a flat background. There is electric light line direct connection type (SCR-200TA). A performance is completely the same and notification distance is prolonged very much from the battery formula. An outside is the same size as KRT-400TA, although the antenna of exclusive use is attached. And since a battery is unnecessary, once it installs, it can use semipermanently. A remote control signal does not overlap with the remote control signal of others only G channels.
The (KRT-400T) is the smallest and epoch-making transmitter in the world in which a device of voice transmitter and control signal receiver is built. Only install the transmitter in setting the power supply switch "ON" at a place to catch sound. An electric wave does not always release and it begins to send wave upon receipt of instruction signal to "Start" from the remote control receiver (KRT-400R). Set the switch "OFF" on the receiver, then, stops to send wave automatically by which extra wave is saved. The available distance is about 200 meters in use with an exclusive remote control receiver. The battery life is 2 days and a half in continuously transmitting but it is extended to 15 days under the condition that is intermittent releasing. In other words, the battery life is available for 10 days if monitor 1 hour per day. The battery adapter (AD-RT) is available to extend the battery life by 30 times and enable to control operation for "Start and Stop" automatically in connection with a Surveillance camera, a Video transmitter and other electronic devices driving with batteries placed outside. The remote control transmitter (KRT-400TA) is supplied power in direct connection with an electric light line so that no battery is required and it is available semipermanently once installed. It can be installed and hidden in a wall outlet or some electric apparatus.
The notification distance of an electric wave doubles [ about ] by the same outside [ be / a powerful type micro remote control transmitter (KRT-800T) / just like that of (KRT-400T) ]. Continuation use is carried out and it is the battery life of about 6 hours. If it is hearing of about 2 hours per day, it will have about three days. (Alkali dry cell) . A battery adapter is used when using continuously for a long time. AD-RT3 (about 4 times of a U5 dry cell), AD-RT (26 times of a U5 dry cell). A unnecessary electric light line direct connection type powerful type remote control transmitter (KRT-800TA) also has a battery. A performance is the same as that of KRT-800T. The external antenna of exclusive use is attached. A receiver uses (KRT-800R) of exclusive use. Received frequency is only DEF. A remote control signal is only E.
For various types are available, optimum type can be picked up according to the purpose. Camouflage types looks like a ball-point pen (KPK-300), (KPV-300), a credit card (CD-500), (CDV-500), a small calculator (CD-500C), (CAL-202) are available. The ball-point pen type can write and the credit card type is very thin so that it is hidden in a name card case. The calculator type is useful as a conventional calculator.
- Regarding the transmitters used in direct connection with an electric light line at home, 3 plugs outlet type (KAZ-110), (KAZV-110), (KBZ-110), (KBZV-110) , (KCZ-110) and super compact type (KNN-110) which is installed in a wall outlet and various electric apparatus are available. These compact type transmitters are available for semi permanent upon installation because of no battery is used. CAL-202, CDV-500, KAZV-110, KBZV-110, KBZV-110 and KNN-110 are released upon sounding to send wave so that an extra wave is saved unless catch sound or voice that the transmitter installed is very difficult to discover. Also, these transmitters are available in automatic recording and the transmitters driven by batteries can be prolonged the battery life several times.
- (KTK-400) is a multi function and catch minute sound transmitter in general use for tapping. An exclusive antenna is required by which the available distance to be extended 2 times in compare with other type transmitters. This type transmitter is made to change its functions according to the purpose in use. For instance, in case to catch a minute breathing in asleep, the transmitter release wave continuously and set to release wave upon sounding to hear a usual conversation. In setting to release wave upon catch a sound, the battery life is extended to several times and, in a short distance, it can be decreased to release power for wave so that the battery life to be extended furthermore. On the grand without any obstruction and attach a Yagi antenna used exclusively with the receiver, the available distance to be extended to about 400 meters in releasing wave continuously.
- (KTK-800), It is a multi-function strong power type transmitter to catch a minute sound. This type transmitter can be used for a long time in connection with a voice microphone or a contact microphone placed outside. It is optional to use in releasing wave upon catch sound or release wave continuously either by turning of the switch. The wave is to be selected "High" or "Low" and one battery is used for "Low" and 2 batteries are used for "High". The battery life is nearly 3 days on "High" and 6 days on "Low" in releasing continuously. In proper using, the battery life will be extended furthermore to 10 days. In using of a lithium battery, it works steadily regardless of temperature as well as a long time use. The available distance is 300-600 meters and if set on "Low", it will be a half of the distance. However, some decrease of the distance in the space where many houses and buildings are built is unavoidable for which the way to release wave continuously is recommendable. The (KUR-400) and conventional one for UHF band types sold in the market are available However, an exclusive receiver must be used when to catch a very low voice in whisper. Conventional one has a problem to hear due to noise makes by itself.
- (KT-400) is available at a low price without function of releasing wave upon catch sound and function of selection high and low power.
- (KT-400N) .The small, efficient hearing transmitter of the outside needle mike with shield wire. It penetrates there if there are 2milli hole (Diameter 1.5 millis of the needle) and the conversation of the next room flies by the electric wave if it sets it up because needle (injection needle) mike has ten-centimeter length of the needle. The special order and there is an injection needle of 20 centimeters, too. (Jyen3,000). Because the lithium battery(CR2) is used, it differs from the dry battery, and it operates in an always steady state regardless of an external temperature or the use time (in the tolerance). The distance range of the electric wave is from 100 to 200m.
- (KT-400D) is the same type as KT-400 and extended available distance to 300 meters.
- (KTL-400) is available at a low price for long battery life for 6 days and available distance is more than 200 meters.
- Powerful type minute sound hearing transmitter (KTL-400K) notification distance is the cooperated type transmitter which is 500m. Two dry cells of a U5 are used. Although a battery life is 8 hours, if a battery adapter (AD-L) is used, it can be used for a long time.
- (KTLV-400) is type that wave is released when it catch sound so that the battery life to be continued for 10-30 days, if it is monitored 5-6 hours per day.
- (KT-800) is high performance and strong power tapping transmitter for a long time use. Four dry cell No.3 batteries are used and if a alkali battery is used, the battery life to be 3 days and a half. With oxide battery is useful for 5 days. Lithium battery is useful for 7 days in operation continuously. The particular circuit to supply voltage steadily is built by which the power to release wave is no problem just before the battery life is completely exhausted even the voltage of the battery is low down on the way. The available distance is 300-600 meters but, it may be shorter in the place where many houses and buildings are available.
- If it is a problem that no sound or voice to hear on the target time with the type of a transmitter which is begun to release wave upon catch sound, (KKCR-360). Automatic recorder is recommended. Recently, a super compact IC recorder possible to record for more than 10 hours being sold in the market.

- The transmitter is very effective to discover a dementia old man wandering with the transmitter and no problem even he has the transmitter because of it being light weight as well as no conspicuous to carry.
- When a car is stolen, the transmitter should be very helpful to discover the car for it can narrow down the location within an area of the radius of less than 100 meters though a rough location is known with cell phone with GPS or PHS information service over very wider area. Besides, they are not available, if the car being parked at the underground parking area in building in down town.
- The valuable jewels in an attache case in which the transmitter is attached are stolen or left carelessly somewhere in carry, the jewels placed in any location all over Japan are surely discovered in use combined with PHS information service for location unless the attache case can be opened.
The discovery receiver for tracking
The high sensitivity three-channel-micro-discovery receiver (KRS-300)for tracking can catch a wave released by the transmitter not only for tracking but, also a wave released by every type transmitter except an intermittent type transmitter to know the location of the transmitter definitely. For a special compressed amplifier developed by us is built inside of the discovery receiver, it is possible to catch the wave from a position away to a position by the transmitter in hearing of sound of frequency in variation time to time in accordance with the distance by which the direction and a distance are to be learned with an earphone to reach the object. It is a guidance that sound is going to change as "pu, pu, to pi, pi" in closing to the object. Also, it is available as a conventional three-channel receiver in change of the switch with which can hear a minute sound of which a conventional receiver sold in the market cannot. If Yagi fabricated antenna is attached, the object must be caught more clearly from the distance 1.5 times away. Don't touch the magnet of the transmitter for tracking to the receiver for the receiver should be broken upon it does and not recover unless it is repaired.
The three-channel-super-micro-discovery receiver (KRS-300S) is made of the same function on KRS-300 completely to catch a wave released by our intermittent transmitter. It can be distinguished what type transmitter to send a wave in change it to receiver. If the receiver catch a sound "saa---" , it is the sound that a wave sent by an intermittent transmitter. Don't attach the magnet of the transmitter for tracking to the receiver for the receiver should be broken upon it does.

Receivers
- For our all receivers are designed under the condition that the noise made by the circuit itself to be lessened to the limit, our receivers enable to be tremendous higher performance in comparison with the conventional receivers sold in the market. Regarding the conventional receivers may be no problem in case of hearing of a conversation under the normal condition, however, it is no use to hear a very low voice in whisper due to the much noise.The various receivers which are exclusively used for our transmitters are available such as the two-channel receiver (KKZ-100) developed more than10 years ago, the latest model of micro-three-channel receiver (KUR-400) and the three-channel-automatic recorder (KKCR-360).
- The super micro type receiver (KUR-400) is the latest model designed depending on our motto to pursue that our products must be small as well as high performance as possible. It is the newly developed super micro receiver built even a speaker in a palm size ever not been made in the world. It is designed successfully to be high sensitive as well as the KKZ-100 in very little consumption of current. The dry cell No.5 battery which is popular in the market is used. The battery life is nearly 3 days in continuous use with an earphone. Two types of A.B.C .and D.E.F. are available.
- The scramble receiver (SCR-100R) is an exclusive receiver for the transmitter (SCR-100T). The external shape and the function are completely the same of KUR-400 except a speaker. However, a wave released by a conventional transmitter is unable to catch. It is restored automatically in trace to the carrier of the transmitter synchronously. When it is synchronized, a click sound is available slightly. The receiver and the transmitter are a pair of use to hear due to a difference of order on repetition of the carrier. Six systems are available and it is quite simple in operation. It can receive a wave immediately upon power being supplied. The battery life is more than two days in continuous supply. The particular type (400 MHz + - 5 MHz a paired with a transmitter) is possible to make.
- The scramble receiver remote control type (SCR-200R) is an exclusive receiver for the scramble remote control type transmitter (SCR-200T). The scramble transmitter begins to releases a wave upon set the power switch "ON" of the receiver otherwise the transmitter does not release a wave since only the exclusive receiver can catch the wave. It is super micro type. The external shape and the function is the same of KUR-400 though a thickness is increased by 3 mm. The receiver is restored automatically in tracking to the carrier of the transmitter synchronously. When it is coincided a click sound is slightly available. The receiver and the transmitters is a pair of use due to a difference of order on repetition of the carrier. The six systems are available. It is quite simple in operation. It can receive a wave immediately in set the power switch "ON". The battery life is more than 3 days in continuous use.
- It is the epoch-making product which contained the control signal transmitter and the receiver in the same size as (KUR-400) of micro remote control receiver (KRT-400R) smallest-in-the-world size. A remote control transmitter (KRT-400T) (KRT-400TA) and a set use. It is immediately receivable if a power supply switch is set to ON to hear it. If the switch of a remote control receiver is cut when stopping, dispatch of the electric wave of a remote control transmitter will also go out automatically. An unnecessary electric wave is not sent. The receiving distance of an electric wave is about 200m in prospect distance. A remote control transmitter and a two set set use. It can use also as a three channel receiver ordinarily. A remote control signal is C or F.
- A powerful type micro remote control receiver (KRT-800R) is an exclusive remote control receiver of (KRT-800T) and (KRT-800TA). Receiving distance is about 400m. Received frequency is only DEF. A remote control signal is only E.
- It is certainly possible to tap a conversation on telephone from any place all over the world in use our receivers such as (KUR-400Z) or (KRT-400RZ) in combined with a PHS receives a wave automatically or a cell phone and a wiretap which is a cell phone attached an amplified external microphone. However, it will be impossible to use them if an interceptor is installed in the place. And , furthermore , it must be traced easily if it is discovered and found that who owns it. Now, the problems have been successfully solved in connection with output power released by our new developed super micro KRT-400R to a terminal of an earphone microphone. The PHS attached an amplified external microphone is useful without any change. The tone is very clear and high sensitive tremendously in comparison with the one attached an amplified external microphone. It is surely possible to tap a conversation on telephone from considerable away such as a foreign country in install the workable transmitters such as KTK-400 etc. at a place to want to monitor and place a receiver connected with a PHS within an area where possible to catch a wave released by the transmitter. When the telephone is hanged up, the circuit of PHS stops automatically within 30 seconds. The models available to combine with a PHS are KUR-400Z and KRT-400RZ which are modified with KUR-400 and KRT-400T. It does not spoil the original function as well as not change the external shape as it is only attached a function to connect. Also no consumption of a battery of the receiver is available under the condition that the PHS does not call for development of a new circuit switch "ON" only at the time a PHS works. If it is monitored for one hour per day, it must be useful for more than two months. No consumption of a battery of the receiver is available unless the PHS is called. KRT-400RZ is used combined with KRT-400T so that the transmitter only releases a wave during the time that the connected PHS being called by which hardly any case of discovery by a detector.

Special devices
- (KAB-7). Does the plug terminal of the contacting mike of the attachment or the needle mike to the input terminal in front of the main body. The switch on the side is set in either. It sets in there is a red point for the contacting mike and it sets it in opposite for the needle mike. Next, front volume adjustment knob (VOL) is adjusted to the position of 0. And, the earphone of the attachment is inserted in Jack on the side. In addition, VOL is adjusted until the detection part of the vibration mike is applied to the wall, and the sound of the earphone becomes a suitable volume. It has it by the hand, and because it becomes difficult to hear by a little vibration's becoming a large noise, the contacting mike is fixed with the packing tape and used. The needle mike penetrates there if there are about 2milli hole and is used. It is possible ..distinctness degree.. to do by operating the filter circuit when there are a lot of noises in surroundings. The characteristic of the filter can be selected with the switch of the sign of A, B, and C on the side on the power on/off switch and the other side. A hears of the sound that state and C of one CR high-pass filter step passed the CR filter and the band-pass filter ..flat characteristic without the filter and B... Please decide the best position suitably while hearing it. If the slide is done back, changing the battery sees the battery the battery lid on the back of the back.

- The two models of (RP-300A) and (RP-300D) are the repeater to relay a wave released by a tapping transmitter. The RP-300A receives 399 Mhz and oscillates 320 Mhz and the RP-300D receives of 320 Mhz and oscillates 399 Mhz They can change respectively three of ABC and DEF for receiving and two of DF and AB for oscillating with a switch. In other words, many repeaters are available in connection with each other. It does not release a wave even though a switch for power supply is putting on. Only when a receiver in the repeater receives a wave , it begins to release a wave and it works at an intervals of 2 seconds intermittently under pending so that the consumption of current is 1/7 of the case of continuous operation.. It is adapted to the transmitter to release a wave upon catch a sound. Once a wave stops, it does not move to intermittent release of a wave for 10 seconds. The battery life is 5 days in continuous use, however, it is prolonged to 10 days or even 20 day in use with the transmitter works upon catch a sound. The available distance to relay is 700-1000 meters
