Ball-point type transmitter for tracking
KPB-300


Outline
  • It is small and is an inconspicuous transmitter for tracking .
  • When it should be accompanied by the child and it should stray at an amusement park, a department store, etc., if the transmitter is given to the child, it can discover easily.
  • It is the transmitter used for tracking of the move object in a short distance. It transposes to the dial tone (beep sound) which is intermittent in a microphone portion by the same outside as KPK-300, and is intermittent at intervals of 0.3 seconds in the most sensitive sound of 1000 cycles at a man's ear. Since an audio circuit operates while [ 0.3 seconds ] the dial tone of 1000 cycles has stopped, it carries out striking, when it approaches etc., and a dispatch object can be discovered.
  • A battery uses two oxidization silver batteries (SR-48W). It can use by continuation use for 6 hours. If it uses intermittently, it will be obstructed a total of about 12 hours.
  • The notification distance of an electric wave is 30m or 100m. In the place where the inside of a building and the house build and are crowded, notification distance becomes short.
  • Although it is made so that it can discover with a commercial discovery vessel, it is easily discoverable if directive Yagi Antenna (NY-399B,NY-399C) and the three channel discovery receiver (KRS-300,KRS-300S) for tracking are used. And even the radius of 150m can be discovered.
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 (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 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.
  • When giving a person, it is made to give in the state where it separated from the body as much as possible. It puts into the pocket of clothing which is an outside most.
  • 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. 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.
  • In order to discover, the three channel device (KRS-300,KRS-300S) for tracking is used. At first, it has a device before the body so that an antenna may become perpendicular, and a point is carried out once, and it feels and comes out, and turns around the body slowly. A tone or the direction which was able to be heard most highly becomes in the direction with a transmitter. If it moves to that one, since the dial tone changes to a high sound called steps "Phii" , it moves to the direction which becomes the highest sound. A commercial discovery device and UHF band with Yagi Antenna Although a multi-channel receiver can also use, we recommend you the exclusive device in which prolonged use is micro and possible.

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..
