Output Upper-limit
- Blinking green while processing the
algorithm
-
Blinking red while shutting down for
30 mins.
-
Solid red while fully shutting down
This alarm is raised when output power is
over +2 dB than rated output power.
B20 800MHz : 13 dBm
B3 1800MHz : 15 dBm
B1 2100MHz : 16 dBm
①
Access to the LMT and check input power level.
②
If the power is strong, insert a suitable attenuator into
the coaxial cable between the antenna and the re-
peater.
※
Rated input power range
B20 800 MHz : -54 to -24 dBm
B3 1.8 GHz : -52 to -22 dBm
B1 2.1 GHz : -51 to -21 dBm :
③
If the power is still strong, change the antenna location.
Output Lower-limit
- Solid orange
This alarm is raised when output power is
being lower than lower-limit for 5mins.
①
Access to the LMT and check input power level.
②
Check cable connection status between a Donor An-
tennas.
③
Check the device output lower-limit level is set cor-
rectly.
④
If the input power is normal but the output power
reaches up to lower-limit, check the antenna isolation is
sufficient.
⑤
If the isolation is not sufficient, change the location of
the repeater or turn it away from the donor antenna.
UL Output Upper-limit
- Blinking green while processing the algo-
rithm
- Blinking red while shutting down for 30
mins.
- Solid red while fully shutting down.
This alarm is raised when output power is
over +2 dB than rated output power.
B20 800MHz : 20 dBm
B3 1800MHz : 20 dBm
B1 2100MHz : 20 dBm
①
Access to the LMT and check output power upper-limit
is set correctly.
②
Check the isolation is sufficient.
③
If the isolation is not sufficient, change the location of
the repeater or turn it away from the donor antenna.
