User manual:
1. Power setting
   Press and hold the button P to choose the power of 25mW/200mW/600mW.
   Use two short press to turn on/off the transmitting(PITMODE  setting) and then the TX LED will be twinkles( on and off alternatively) or not respectively. When power is set to OFF(PITMODE is effective), you can set bands and channels without interference to others.The AV transmitting distance is only within 1-2 meters  when it is in Pitmode.
   Only the TX LED is on when the power is set to 25mW,both two lights of TX and 200mW LED are on when set to 200mW, All three lights TX,200mW and 600mW are on when set to 600mW. 
2. Band and channel setting
   Presss and hold the button C to choose the band A-b-c-d-E-F(circle).
   Press the button repeatedly to choose the channel 1-8(circle).
   When PWM port is connected with a RC receiver, it can been used to change AV channels 1-8 and to shut transmitting by a RC( PITMODE in effect). Make sure that there is a PWM signal from receiver within 3 seconds after powering up ,otherwise the transmitter is back to button-press setting mode . When in the setting mode of PWM, the dot on the digital display will glow  
    For enhanced version e708TM3, Betaflight/Cleanflight OSD setting of power,bands,channels and Pitmode is supported, referring to ‘’for details.  

          1.Make sure that there is enough space for airflow when installing the module   on the drone in case the overheat protection starts to reduce the power even to shut down at the worst.
          2. Please install the antenna before powering up for a longer use life.
          3.The maximum current of output DC 5V is 800mA.
