Powerful type transmitter release a wave intermittently for tracking.
KTB-700S


Outline
  • It is an intermittent transmitter only for tracking reference. About four 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 80 times. (Since circuit drive current is required in practice, it increases about 40 times.) An intermittent transmitter does not react to a commercial discovery machine or a commercial receiver. Moreover, it does not react to the discovery apparatus for commercial pursuit. It cannot refer to KRS-300 of our company, either. Reference discovery is possible only KRS-300S. However, it reacts to AM receiver.
  • If it is the flat ground in which a prospect is small and possible, it is the intermittent transmitter for tracking which can be discovered from the 1km away place. In the inside of a building, or a city area, notification distance becomes short.
  • A battery uses two lithium batteries (CR-123A). The continuation use on the 22 [ or more ]th will be possible. Especially a winter season is stabilized by the lithium battery and operates.
  • Since a long distance electric wave arrives, the position of a transmitter can also be decided using a map. It does not search and the place is known simply. It is attached in the powerful magnet with which it can equip easily [ a car ]. Please do not attach this magnet and receiver by any means. A receiver must stop operating and must come to readjust to an instant.
  • 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-399B) is used, the direction of a dispatch object can become clear and can discover easily. And if it is a flat ground, it can discover from the place distant the radius of about 1.5km.
Directions
  • The metallic ornaments of attachment into two hollow portions of the lid of a case are applied, and as it pries, it opens. Since the space which puts in two is in an inside about a battery (lithium battery CR-123A), 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 board. In this case, after dropping surface dirt well, it attaches.
  • 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. If it is in the state where an antenna adheres to a metal plate etc., especially notification distance will become extremely short. 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 wave of strait wire becomes good somewhat from a helical antenna. When you attach in the bottom of a car, please attach an antenna and bend about 1cm about 45 degrees originally in a place. Although an antenna is attached with a screw, please fasten some more strongly not to loosen by vibration of a car.
  • In order to discover, the three channel discovery receiver(KRS-300S) for intermittent dispatch is used. At first, it has a discovery device ahead of bodily so that an antenna may become perpendicular, and it turns slowly by the touch which turns the body. A tone or the place which was able to be heard most highly becomes in the direction with a transmitter. if it moves to that one -- a dial tone -- steps -- since it changes to a high sound, it moves to the direction which becomes the further highest sound Since a direction is clearly known when Yagi Antenna is used, we recommend you to surely use together and to be used. Since an electric wave arrives to remarkable long distance, since a direction becomes unclear, this model should surely use Yagi Antenna with an ordinary antenna. Moreover, on a last-minute point, it becomes a way piece way piece to feel an electric wave. When there are buildings, such as a part in the heart of Tokyo, an electric wave reflects at the building and a direction may not clarify. If an electric wave is received, a direction will be first checked on a nearby footbridge and on the roof of a high building using Yagi Antenna. If still high buildings, such as a building, are situated in near, since it will think that an electric wave reflects with the wall of a building and a transmitter is in the direction of the building, be careful.
  • The place of a transmitter is plotted using the magnet for mountain climbing, and 1/10,000 or less map, and the direction moved to the place can be efficiently discovered without moving about recklessly, since an electric wave arrives considerably.

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-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, a cash card and a telephone card, close to a magnet.
