The powerful type transmitter for tracking
KTB-400D
Outline
- It is a transmitter for tracking being small and for long distance.
- 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 trackingof 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 KT-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, when it approaches, it carries out striking 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 100m or 300m. 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 400m 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 CR2) 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 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
- 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.
