Antenna Installation Warning
1. Any antenna only can be installed and maintained by professional technician. Please make sure that the
radio station is closed when you maintain or work nearby the antenna.
2. In general, radio will be connected to a directional (high-gain) antenna, and fixed to the edge or top of
building or top of tower. According to the application and antenna gain, total hybrid power may exceed
90W (ERP). Under normal circumstance, only the professional technicians can close to the antenna area,
anyone can’t touch the antenna or close to 2.3m in diameter range of the antenna.
Antenna Gain vs Safe distance recommended
Antenna Gain: Maximum 3.5dBi
Safe distance: 2.30m

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 transmitting indicator
When data transmitting, LED indicator of TX will turn red flash.
4、Radio setting
