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
a 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（HX-U101）
0–5 dBi 5–10 dBi 10–16.5 dBi
The minimum safe
distance

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, please turn on the low voltage protection; if LED indicator of ON is red, which means
the voltage is too high, please turn on the overvoltage protection.
3.2 Low power switching
Pressing the button of PWR for switching between high power and low power. If you choose high
power, LED indicator of PWR will turn red; if you choose low power, LED indicator of PWR will turn
green.
Default value: high power.
3.3Transmitting channel switching
Pressing the button of CHANL, 8 channels of “1-8”will be switched within each other, keep

[User Manual]
pressing for fast forward, digital tube display the current channel number.
3.4Channel Display
Operation Mode: Display the channel number of “1-8”transmitting rate.
3.5Low voltage indicator
While transmitting data，TX/RX LED indicator of ON will be red flash；While receving data，
TX/RX LED indicator show green.
