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.
  • Since dispatch of an electric wave is a sound perception starting system, if sound is lost, it will not send an electric wave. An unnecessary electric wave is not sent. Therefore, others become are hard to discover with a locator etc.
  • 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 whisper voice can also be caught clearly.
  • A battery uses two oxidization silver batteries (SR-48W). If it uses intermittently, it will be obstructed a total of about 12 hours or far more.
  • A receivable distance is about 100m.
  • An exclusive receiver (KUR-400) is used for receiving. If Yagi Antenna is used for a receiver, a receivable distance will be prolonged by 1.5 times.
  • Automatic recording for 5 hours is made using (KKCR-360). Prolonged automatic recording is made using the commercial recorder with a voice starting recording function.
  • It can be heard in the place about 1km away using relay equipment (RP-300A).
Directions
  • 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 (SR-48W oxidization silver battery ) are put into the removed nib portion in piles so that + side may become the back. And if a main part portion is twisted 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 the left, a switch will go out.
  • 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.
  • When taking out a battery, a back battery may not come out. Please strike against a wooden board lightly and remove. In this case, a thin stainless wire may separate. If it does not put in as before when it separates, a switch will stop entering. Be careful at the time of exchange of a battery.
  • 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.
  • If a cap is turned down and looked up to perpendicularly, an electric wave will be discharged best. A book etc. is placed without carrying out beside direct and placing on the desk made from steel, and it is made to place on it. Moreover, the surroundings of a main part, on less than 5cm, it brings close to a metal thing and is made not to put. If it puts in into a metal case etc., an electric wave will stop hardly being transmitted.
  • Commercial UHF band Although it is receivable with a multi-channel receiver, 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.
  • 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 digital IC recorder is used, a part for 10 hours 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 Be careful of on--off of a switch so that impossible power is not applied as carefully as possible.
  • Please do not attach a magnet in a main part. An electric wave does not become weak or it stops coming out..
