Hardware

Basic operation

Buttons

Basic operation

Power button: Press the Power button for 3 seconds to power on the radio, press the power button 1 second to turn off the radio.

TX indicator: the indicator will blink when the radio is transmitting.
Up: press to left/up.
Down: press to right/down.
Enter: press to enter/confirm.

Display

Low Power alert: the display will show “POWER LOW” if the power voltage is less than 10V.
Display
Sleep mode: if no operation on the radio buttons for 10 munites, the display will shut down to save power, the power indicator light will still on, TX indicator light will continue blink.

Operation

Press to select the parameter you want to modify, press to enter this parameter setting, press to modify it, press to confirm and exit the setting.

**Channel (CH)

**

Press to CH setting, press to start radio channel setting, press to modify it, press to confirm and exit the setting.

**Frequency

**

Press to frequency setting, press to start radio frequency setting, press to move the cursor, press to modify the frequency, press to confirm and exit the setting.

( Frequency range: 410MHz ~ 450MHz, or 450MHz ~ 470MHz.
If one of the channels frequency is in 410MHz ~ 450MHz, the other channels frequency will be in 410MHz ~ 450MHz too. Otherwise if one of the channels frequency is in 450MHz ~ 470MHz, the other channels frequency will be in 450MHz ~ 470MHz too.
If one of the channels frequency changes from 450MHz ~ 470MHz to 410MHz ~ 450MHz, the other channels frequency will automatically reduce 40MHz. Otherwise if one of the channels frequency changes from 410MHz ~ 450MHz to 450MHz ~ 470MHz, the other channels frequency will
automatically pluse 40MHz.
