Power adjustment

The output power of the machine in two stages:
High-power file (H): >7W;
Low power file (L): <1W

Turn off the power adapter, disconnect the transmitter power finish line state to follow these steps:

1. First press and hold the power switch ,and connect the power (DC 12V) to the antenna, after 3 seconds after release the key, at this time into the power adju stment status, the LCD display shows "L" or "H" (default image file H high power)
2. Press , and set it as high power (H)
3. Press , and set it as low power (L)
4. Select the desired power profile, and press .power setting finished, and it will into frequency range setting state.

Frequency range setting

1. After the power setting, it will enter the frequency range setting state, power setting is completed, press the LCD screen display shows a set of frequencies, the frequency data is the high-end of the operating band (below)
   
   (Factory default frequency is 108MHZ)
2. For example, to set the operating frequency range of 90MHz to 100MHz, then through the key , adjust the frequency data as 100.00MHz
   
3. Band after the completion of the high-end setting, press key , the band will enter the low-end setting, LCD displayed data band low frequency (below), through key to adjust the data to 90.00MHz
   
   Then press key , at this time the setting finished.
   (Note that the low-end band must not be higher than the high-end band.)
