Alarm Information
VSWR Alarm
High VSWR (voltage standing wave ratio) of TX antenna
connector could result in damage to the PA, and even failure of
the transmitter. When the VSWR exceeds the normal range, the
Alarm Indicator will glow red and the LCD will display the prompt
message below:
Then the repeater will automatically works at low TX power. You
need to:
1. Check if the operating frequency of repeater is in line with that
of antenna. Both frequency mismatch and improper antenna
could result in poor transmitting performance and even
damage to the transmitter. If yes, please contact your local
dealer to replace the antenna or reprogram your product.
2. Check if the connection between the transmitter and RF cable
or antenna feed line is loose or damaged. If yes, secure or
replace the cable or antenna feed line.
3. If you cannot solve the problem, contact your local dealer for
technical support.
When the VSWR falls within the normal range, the prompt
message will disappear, and the Alarm Indicator will go out.
Low Forward Power Alarm
When the forward power is below the preset value, the Alarm
Indicator will glow red and the LCD will display the prompt
message below:
Then the repeater may continue transmission or terminate it,
subject to the detection result. You need to:
1. Check if the connection between the transmitter and RF cable
or antenna feed line is loose or damaged. If yes, secure or
replace the cable or antenna feed line.
2. If you cannot solve the problem, contact your local dealer for
technical support.
When the forward power is recovered to its normal value, the
prompt message will disappear, and the Alarm Indicator will go out.
Over/Low Voltage Alarm
When power voltage is detected to be over or below the normal
range (11V-15.6V) of repeater, the Alarm Indicator will glow red
and the LCD will display the prompt message below:
High VSWR!
Low Forward
