Transmitter for tracking looks like a card send a wave intermittently. 


 CD-500S






Outline
    

  • It is the transmitter which is not conspicuous although a man is given. It is the same outside as CD-500. The time use on continuation the 40 days will be possible for a battery life. 
    

  • It is easily discoverable if the wandering old man is given. 
    

  • If the child is given, when prodigal, it can discover easily at an amusement park or a department store. 
    

  • 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 about 120 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 tracking . It cannot refer to KRS-300 of our company, either. Reference discovery is possible only KRS-300S. 
    

  • A battery uses a lithium battery (CR2430). As for this battery, a winter season also operates stably. 
    

  • The notification distance of an electric wave is 50m or 150m. In the place where the inside of a building and the house build and are crowded, notification distance becomes short. 
    

  • It cannot perceive with a commercial discovery device. 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 together tracking, the direction of a dispatch object can become clear and can discover easily. And it can discover from the place which at least the radius of 200m left. (Flat ground in which a prospect is possible) 
    

  • If a receiver is quickly moved when pursuing, sound will change in stairs. Since a received electric wave level is updated 4 times in 1 second, if it moves quickly, it will become incomprehensible somewhat. 
    

Directions
    

  • The battery lid by the side of the main part reverse side is removed. Pressing down a battery lid top with the thumb of a hand, power is applied so that it may shift outside. If it shifts about 5mm, a lid will separate that it is natural. A lithium battery (CR2430) is put into the portion which a main part is round and was dented so that + mark may turn up, and a lid is slid and shut into it as before. 
    

  • An about 1mm slide switch is in the horizontal side by the side of a battery. It is shifted to the direction of a red mark. Then, it will be in a state of operation and an electric wave is sent. 
    

  • When giving a person, it is made to give in the state where it separated from the body as much as possible. It puts into the pocket of clothing which is an outside most. 
    

  • In the place where the inside of a building and the house build and are crowded, how to transmit an electric wave becomes bad and a receivable distance becomes short. Moreover, the strength of the electric wave discharged in the air changes also depending on how to place a main part. An electric wave is discharged having stood and placed most efficiently [ direction ]. moreover, the surroundings of a main part, bring a metal thing close and it is not put on less than 5cm It carries out for obtaining. If it puts in into a metal case etc., an electric wave will stop hardly being transmitted. It is made to put into an outside pocket most so that it may separate from the body as it becomes, when giving a man. 
    

  • In order to discover, the three channel discovery receiver for tracking (KRS-300S) is used. At first, it has a device before the body so that an antenna may become perpendicular, and it turns slowly by the touch which turns the body. 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 -- a dial tone -- steps -- since it changes to a high sound, it moves to the direction which becomes the highest sound Since it is detectable from the place which the direction was found clearly and also separated the electric wave from the helical antenna about 1.5 times if Yagi Antenna is used, we recommend you to surely use together and to be used.

Notes
    

  •  Please twist a main part or do not throw it. It becomes the cause of failure. 
    

  •  Please do not attach a magnet in a main part. An electric wave does not become weak or it stops coming out..
