• It is the micro UHF band narrow-band FM transmitter unit of the voice starting dispatch with built-in high impedance audio amplifier of 50db.
  
• It is possible for it to be intermittent by the existence of an audio input in an electric wave output.
  
• It is very efficient. When power supply voltage is 3V, a high frequency output is set to 6mW by consumption current by 9mA.
  
• By changing power supply voltage, it can carry out variable [ of the high frequency output ].
  
• The characteristic of unnecessary radiation is excellent. (-50 or less dbs)
  
• It is micro. It condenses to the size of 12x18x6mm with the newest technology.
  
• Inclusion is possible to various apparatus as exciter of FM transmitter again as a feeble electric wave transmitter of various data.
  
• It excels in the stability of transmitted frequency and shines. It is less than �}2 Khzes in the normal temperature range (-10 - 50 degree C).
  
• Various remote sensing is possible combining a micro receiver unit (BD-URZ).
  
• It is the internal unit of various transmitters (KTK-400, KTLV-400, KAZV-110, KBZV-110, CAL-202, KNN-110).
  

• Above figure left Out is the output of an electric microphone (Mic) and Freq Adj is fine tuning of oscillation frequency.
  
• Center of the above figure Sound starting dispatch control It is in the state which attached boad.
  
• The consumption current at the time of standby is 0.5mA or less.
  
• Adjustment of the level of a audio which carries out connection and cutting is adding a resistor to the input part of a control base, and can lower sensitivity.
  
• As for the center of the above figure, in the back of the left figure, Ant becomes an antenna terminal with a high frequency output terminal. GND is a grounding terminal. DC Sup is a power supply terminal. 1stReso Adj is alignment adjustment of a 3 times as many resonance circuit as crystal oscillation frequency. 3fAdjs are 3 times as much resonance adjustments as that further. 9fAdjs are 3 times as much resonance adjustments as that further. LP Filt adjusts attenuation of the harmonics of an output electric wave. output frequency -- 27 of a crystal oscillation -- it has doubled
  
• Since the main part is an adjustment, it only connects a battery and an antenna and can use them as a hearing transmitter with sound starting function immediately.
  
• A built-in electronic microphone is removed, various sensors (a vibrograph, a heartbeat meter, pulse meter, etc.) are directly attached in the portion, and remote sensing becomes possible.
  
• An exclusive receiver (KUR-400) is used for receiving. Or it is also possible to make a micro receiving unit (BD-URZ) build in various apparatus, and to receive. Commercial UHF band Although it is receivable with a multi-channel receiver, tone quality is bad or a receivable distance becomes short.
  
• If an option (sound starting dispatch system) function is used, prolonged automatic recording will be attained combining the recorder of a voice starting recording system.
  
• If the newest IC recorder is used, a part for 8 hour or more can be recorded continuously, and what was moreover taken in and saved in the personal computer can also be reproduced and heard.
