When this alarm segment is displayed, the repeater will
still work properly and will power off automatically when
running out of power.
In this case, you need to take the following measures:
1. Check the power indicator on the power supply
management system to see if the power is low. If
the power is low, please charge the power supply
management system or replace it.
Caution: When an external power
supply is connected, the repeater will
power on automatically.
2. If you cannot solve the problem, contact your local
dealer for technical support.
When the battery power is higher than the low-battery
alarm threshold, the alarm will be eliminated with the
segment disappearing and the alarm indicator going out.
External Power Abnormal
When powered by a power adapter, the repeater will
have real-time detection of the output voltage of the
power adapter. When the output voltage falls off the
range of the operating voltage, the alarm indicator will
glow red and the LED segment display will show “E3”.
When this alarm is given, the repeater cannot work
properly and will power off automatically in 3s. If the
automatic powering off is caused by the external power
supply error, the repeater will not power on automatically
after it returns to normal operation. You will need to turn
it on. If the power supply returns to normal operation
within the 3s, the alarm will be eliminated so that the
repeater will not power off.
In this case, you need to take the following measures:
1. Check whether the power adapter is damaged. If it is
damaged, please replace it.
2. Check through the voltmeter whether the voltage
inputted by the external power supply is over low
or over high. If it is over low or over high, please
replace it or use the battery for power supply.
3. If you cannot solve the problem, contact your local
dealer for technical support.
TX/RX Unlock
Normally, after being powered on, the repeater has its Tx
and Rx work properly in locked status. Once the repeater
detects that the Tx/Rx PLL is unlocked, its alarm indicator
will glow red and there will be a sign (“E4” for Tx Unlock,
“E5” for Rx Unlock) on the LED segment display.
Tx Unlock Alarm
Rx Unlock Alarm
When such alarm is given, the repeater will terminate
part of its features automatically. Now you will need to
contact your local dealer for technical support.
When Tx/Rx returns to the locked status, the alarm will
be eliminated with the segment disappearing and the
alarm indicator going out.
Over Temperature
When the operating temperature of the PA module is
higher than 85
℃
, the alarm indicator will glow red and
the LED segment display will show “E6”.
When this alarm is given, the repeater can still work
properly. During a rise in ambient temperature, the
repeater will keep track of the Tx power with adjustments
in order to lower the temperature.
And you need to take the following measures:
1. Check whether the ambient temperature and
ventilation conditions of the repeater satisfy the
foregoing installation requirements. If not, please
make improvements as soon as possible.
2. 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.
3. If the above measures fail to solve the problem,
contact your local dealer for technical support.
