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.
