Module Features:
  1) board design of the audio interface, you can directly insert the microphone or audio signal line, the use of very convenient.
  2) module with a regulator chip, wide operating voltage, good stability.
  3) The back of the module with 5 small buttons, easy to set the frequency, and input signal gain.
  4) module width just for the No. 5 battery diameter, easy to install into the battery box to complete a complete launch system.
  5) Module support - input audio signal amplitude adjustment and microphone sensitivity adjustment
  6) Subwoofer boosted
 
 
Instructions:

S1: press S1 once, the frequency reduced by 0.1Mhz (long press S1 button for 5 seconds, can restore the default value: working frequency 100Mhz, spirit
    Sensitivity 6)
S2: press S2 once, the frequency plus 0.1Mhz
S3: press S3 once, the frequency minus 1Mhz
S4: press S4, frequency plus 1Mhz
S5: Input signal sensitivity control (level 1-8)
 
 
note:
   Module power after 3 seconds into the working state, each time the key operation will automatically save 3 seconds. When you do not know the module's operating frequency, you can press the S1 button to restore the default value of the module: 100MHz, the input sensitivity of 6
   The module is made using a phase-locked loop chip, so the work is very stable, even if the human body touch the antenna will not cause changes in the module frequency, you can rest assured that use. Module power to receive, receive antenna with headphone cable and can also be used to separate the antenna, the choice of soft wire or rod, the effect is better.
    Modules are factory calibrated by the spectrum analyzer, the quality can be assured.
