Alarm Information
The repeater can automatically detect its operation status in real
time. If the appropriate alarm indication option is checked in the
CPS by your dealer, the LCD will give you a prompt message, and
the Alarm Indicator will glow red in the case of a corresponding
abnormality.
Over Temperature Alarm
When the temperature of PA module exceeds the normal range,
the Alarm Indicator will glow red and the LCD will display the
prompt message below:
Then the repeater will stop transmitting, and you need to:
1. Check whether the temperature of heat sink surface is over
80
℃
. If yes, proceed with Step 2 and 3 to fi nd out the cause.
Caution:Caution: DO NOT touch the heat sink surface to
avoid burn. You can use a digital thermometer
with thermocouple to measure the temperature
value.
2. Check whether ambient temperature and ventilation conditions
satisfy the foregoing installation requirements. If not, please
make improvements as soon as possible.
3. Check if connection between the transmitter and RF cable
or antenna feed line is loose or damaged. Poor connection
between them could cause high TX power, which would make
the temperature of the heat sink rise quickly. If yes, secure or
replace the cable or antenna feed line.
4. If the above measures fail to solve the problem, contact your
local dealer for technical support.
When temperature falls into normal range, the prompt message
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 message below:
Then the repeater will automatically work at low TX power, to
protect the transmitter from overheating. You need to:
1. Check whether the fan is blocked by an object. If yes, remove
it.
2. If you cannot solve the problem, contact your local dealer for
technical support.
When the fan recovers normal operation, the prompt message will
disappear, and the Alarm Indicator will go out.
