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 find out the cause.
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 feeder is loose
or damaged. Poor connection between them could cause high TX power, which would
make the temperature of heat sink rise quickly. If yes, secure or replace the cable or
antenna feeder.
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.
