Transmitter built in a ball point pen camouflaged type with sound starting system
KPV-300


Outline
  • In the ball-point with a cap, it is what built in a set of a transmitter, and a character can be written ordinarily.
  • It is the function which sends an electric wave to sound (voice). While not sending the electric wave, there is almost no consumption of a battery. Compared with continuation dispatch, a battery withstands long use numbers of times.
  • It can use without attaching an antenna outside, since the efficient antenna is built in, and it can completely use without sense of incongruity.
  • Since the microphone of high sensitivity is built in, even if it has put on the corner of the room, the conversation of a low voice can also be caught clearly.
  • A battery uses two oxidization silver batteries (SR-48W). It can use in the state of continuation dispatch for 5 hours. If it uses ordinarily, it will be obstructed for about 10 to 50 hours.
  • An exclusive receiver (KUR-400) is used for receiving. When you hear whisper voice etc., please be sure to use an exclusive receiver. And it becomes impossible to hardly catch the noise which the receiver itself takes out with a commercial multi-channel receiver.
  • Prolonged automatic recording is made to an automatic recorder (KKCR-360) and the recorder of a commercial sound perception starting system.
  • If Yagi Antenna is used for a receiver, a receivable distance will be prolonged about 1.5 times.
  • It can be heard in the place about 1km away using the relay device (RP-300A).
Directions
  • The cap is a hook formula. When writing a character, it is used by covering the direction which is not a nib. It may idle, if it is going to put in a switch where a cap is put on a nib, and a switch may not enter.
  • The battery is built in at the time of shipment. When taking out a battery, the battery included in the back may not come out. Please strike against a magazine etc. lightly and remove. In this case, the thin electric wire of a lead may separate. Be careful of this portion not to throw. If it does not correct as before when it moves, a switch will stop entering. Be careful at the time of exchange of a battery.
  • Although a battery is exchanged, the cap of the main part of a ball-point is pulled and removed. Next, a nib portion and a main part portion are twisted and removed to the left. Two batteries (oxidization silver battery SR-48W) are put into the removed nib portion in piles so that + side may become the back. And if a main part portion is turned and attached in the right, finally it is. If it twists until it stops, the switch of a transmitter will enter. If 1/4 rotation is turned to a contrary, a switch will go out.
  • The notification distance of an electric wave is 30 or about 100m. In the place where the inside of a building and the house build and are crowded, how to transmit an electric wave becomes bad and a receivable distance becomes short. Moreover, the strength of the electric wave discharged in the air changes also depending on how to place the main part of a ball-point. An electric wave is discharged having acted as him and looked up to the cap most efficiently [ direction ] downward. A book etc. is placed and it is made to place on it without carrying out and putting beside direct in the case of the desk made from steel etc. Moreover, the surroundings of a main part, a metal object is brought close to less than 5cm, and it is made not to put it on it. If it puts in into a metal case etc., an electric wave will stop hardly being transmitted.
  • Although it is receivable with the scanner receiver of commercial UHF band, tone quality is bad or receiving distance becomes short. the noise which the receiver itself takes out with a commercial general-purpose receiver especially when hearing whisper voice etc. -- and it cannot catch Please be sure to use an exclusive receiver(KUR-400).
  • Automatic recording for 5 hour is made to an automatic recorder (KKCR-360). Moreover, automatic recording can also be carried out to the recorder with the commercial voice starting recording function using the recording code of attachment in an exclusive receiver (KUR-400). When you make it automatic recording, please be sure to carry out a check of operation. It checks whether make sound with pocket radio etc., an electric wave is made to send, there is no noise in a receiver, and it is finely audible. The recording code of receiver attachment is put with after that in the earphone terminal of a receiver, and the external microphone terminal of a recorder, it sets to sound starting, and a recording button is pushed. Since it is the mechanism recorded only when sound has been noticed, when required, it can be heard collectively later. Since this model is continuation dispatch, the volume of a receiver is adjusted suitably and it sets it up.
  • If the newest IC recorder is used, more than 10 hour can be recorded continuously, and moreover, it can also take in and save and reproduce in a personal computer.

Notes
  • When you do not use for a long period of time, please pick out the battery from the main part. please take out the battery in a place where vibration is applied -- a switch enters freely by vibration
  • Please fasten ON of a switch, having and being made to push in as carefully as possible, so that it may pinch with a finger. Be careful so that impossible power is not applied. hearing it with a receiver, please put in a switch and be sure to come out If it fastens not much strongly, it will damage simply.
  • Please do not attach a magnet. An electric wave output becomes extremely bad. It will stop returning, if it does not readjust even if it removes.
