Alarm Information
The repeater can automatically detect its operation status
in real time, such as PA over-temperature, low forward
power, high VSWR, high/low voltage and fan failure. When
any of the above occurs, the LCD will give you a prompt,
and the Alarm Indicator will glow red.
Over Temperature Alarm
When temperature of the PA module exceeds the normal
range, the Alarm Indicator will glow red and the LCD will
display the prompt below:
Then the repeater will disallow transmission, and you will
need to:
1. Check if the surface temperature of PA heatsink
exceeds 80
℃
. If yes, implement the following steps 2
and 3 to locate the failure.
Caution: The PA heatsink can become extremely
hot at this moment, so DO NOT touch the repeater.
Use a digital thermometer with thermocouple to
measure temperature.
2. Check if ambient temperature and equipment ventilation
can satisfy the foregoing site installation requirements.
If not, please improve environmental conditions at the
site as soon as possible, by mounting air conditioning
equipment or improving equipment ventilation.
3. Check if connection between the transmitter and RF or
antenna cables is loose or lost. If yes, please secure
the connection or replace the cables. Poor connection
between them could result in very high TX power and
thus high temperature of PA heatsink.
4. If you are unable to verify the above conditions, please
contact your local dealer for technical support.
When temperature of the repeater drops into the normal
operating range, the LCD prompt will disappear, and the
Alarm Indicator will go out.
Fan Failure Alarm
When the fan fails to work, the Alarm Indicator will glow
red and the LCD will display the prompt below:
