Long life battery transmitter for tracking
KTB-500
Outline
It is the transmitter for tracking in which super-long life use is small and possible (continuation six days).
When it should be accompanied by the child and it should stray in an amusement park etc., if the transmitter is given to the child, it can discover easily.
Although a rough position is known with position information service of a portable telephone or PHS over a very wide area when vehicles are stolen, less than 10m of radius numbers cannot narrow down. It becomes a backer powerful in such a case.
Since it has equipped with the powerful magnet, it can attach easily [ vehicles ].
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 KTL-400, 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.
Since the lithium battery is used, unlike a dry cell, regardless of external temperature or use time (inside of tolerance level), it operates in the state where it was always stabilized.
The notification distance of an electric wave is 70m or 200m in strength. 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 device, it is easily discoverable if directive Yagi Antenna (NY-399B,NY-399C) and the three channel discovery receiver (KRS-300) for tracking are used. And even the radius of 300m can be discovered.
Directions
Since there is a space which is made to slide the lid of a case at the point of the thumb, removes it, and puts a battery (lithium CR-12600SE) into an inside, a battery is put in there and a lid is carried out.
It is careful of the polarity of a battery to prevent mistakes.
Switch beside a case An electric wave will be sent if it turns to red mark.
An electric wave is transmitted having stood the antenna efficiently [ direction ] perpendicularly. In the inside of a building, and the place where the house builds and is crowded, how to transmit an electric wave becomes bad and a receivable distance becomes short. Notification distance will become short especially if it is in the state where an antenna adheres to a metal plate etc. Please separate an antenna centimeters [ several ] or more from a metal thing, and install it. Notification distance will become extremely short if it puts into inside, such as a metal box. As for notification distance, as for an antenna, 1/4 lambda strait wire becomes good somewhat from a helical antenna.
In order to discover, the three channel device (KRS-300) 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. Although a commercial discovery device and UHF multi-channel receiver with Yagi Antenna can also use, we recommend you the exclusive device in which prolonged use is micro and possible.

Notes
Be careful of the polarity of a battery to prevent mistakes absolutely. If a switch is turned ON by mistake, internal apparatus is damaged, and if it damages, there is danger of emitting smoke.
Please do not attach the magnet for griddle attachment to a receiver (KUR-400, KRS-300, KRS-300S) by any means. If it attaches, a receiver becomes useless at an instant.
Please do not bring magnetic cards, such as a credit card and a telephone card, close to a magnet.
