Powerful type transmitter release a wave intermittently for tracking.
KTB-900S
Outline
- It is an intermittent transmitter only for tracking reference. Seven intermittent dispatch is carried out in 1 second. the width of dispatch of an electric wave -- 1 / 500 seconds -- it becomes short-time electric wave dispatch extremely Compared with continuation dispatch, a battery life can be developed 60 times.
- An intermittent transmitter does not react to a commercial discovery device. Moreover, it does not react to the discovery apparatus for commercial tracking. It is detectable only by (KRS-300S) of our company.
- It is small, and if it is a flat ground, it is the intermittent transmitter for tracking which can be discovered from the 2km away place.
- A battery the dry cell of U3 is used five There will be a battery life on abbreviation the 6th by continuation use.
- The notification distance of an electric wave is 1km or 2km. In the place where the inside of a building and the house build and are crowded, notification distance becomes short.
- It cannot perceive in a commercial discovery device or a commercial receiver. Intermittent dispatch cannot be used unless it is the discovery receiver for tracking of the exclusive use in which cognition is possible (KRS-300S). If directive Yagi Antenna (NY-399C) is used, the direction of a dispatch object can become clear and can discover easily. And it can discover from the place from which at least radius 3K m was separated. (Flat ground without an obstacle)
Directions
The tool of attachment into two hollow portions of the lid of a case is applied, and as it pries, it opens. Since there is a space which puts a battery (five U3 dry cells) into an inside, a battery is put in there, direction of a lid is united, and as it presses down, it closes from a top.
It is careful of the polarity of a battery to prevent mistakes.
Power supply switch inside a case ON (the direction of red mark) An electric wave will be sent if it carries out.
It can be used by the attached powerful magnet by the ability attaching in an iron thing. It attaches, after dropping the dirt of this surface well.
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 discovery receiver for tracking (KRS-300S) is used. At first, it has a discovery receiver 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. Since a direction is clearly known when Yagi Antenna is used, we recommend you to surely use together and to be used.

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.
- When you equip the outside of a car, please be used by carrying out covering with vinyl etc. so that rain water may not permeate in a main part etc.
- Please do not attach the magnet for griddle attachment to a receiver (KUR-400, 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, a cash card and a telephone card, close to a magnet.
