3、Function and operating instruction
3.1 Booting
Press the button of ON/OFF to boot. LED indicator of ON is green, which means
the voltage is normal, and the machine can work normally; if LED indicator of ON is
red flash, which means the voltage is too low, low voltage protection has been worked;
if LED indicator of ON is red, which means the voltage is too high, overvoltage
protection has been worked.

3.2 High/Low RF power switching
Pressing the button of PWR for switching RF power level between high and low.
If you choose high power, LED indicator of PWR will turn red; if you choose low
power, LED indicator of PWR will turn green.
3.3 Transmitting channel switching
Pressing the button of CHANL, 8 channels of “1-8” will be switched within each
other, keep pressing for fast forward, digital tube display the current channel number.
3.4 Channel Display
Operation Mode: Display the channel number of “1-8”.
Software upgraded to boot mode: display “b”.
3.5 Low voltage indicator
When the voltage lower than 10V, radio modem will turn on protection, LED
indicator of ON will be red flash; voltage back up to 10.2V, LED indicator show
green, radio modem will return to normal work.
3.6 Overvoltage indicator
When voltage higher than 16V, the radio modem will turn on protection, LED
indicator of ON turn red; voltage back down to 15.8V, LED indicator will show green,
radio modem will return to work normal.
3.7 Data transceiver indicator
When data transmitting, LED indicator of TX will turn red flash. When data receive,
LED indicator of RX will turn green flash.
