DOS:

1. Check carefully whether connection of RF signal is correct.2. Check the input power supply. Make sure voltage of power supply is in therange of rated working voltage of the repeater.3. Check antenna rack, feed cable and the host is grounded. Groundingimpedance shall be 5ohm.4. Check the echo loss of the antenna and feed system. Voltage StandingWave Ratio VSWR) < 1.5.5. The build and pole must be lightning proof.6. Entrance wire of power supply must pass lightning switch.7. Antenna and cable must pass lightning switch

Remote MonitoringLocal OMT

Operation & Maintenance terminal

(OMT) interact with the

Repeater to set and lookup its

status and RF parameters. Itcan display alarms real-time.

OMT can set local connection,wireless data connection or

SMS connection with the

device for operation and

maintenance at any time, or atany location.

Power Module Alarm

Alarm Reason : 1.AC 220V Power Supply Modules malfunctionSolution Replace the power module

Alarm Reason : 2.Ouput DC Voltage fluctuation is beyond 15% of

Voltage Rating

Solution: Disconnect all power cables to other modules and

connect to power module one by one to check the faulty module

and replace it

Repeater Alarm: Over temp. AlarmAlarm Imitation: PA Temp Limit:85

PA Real Temp:40~60 Adjust the PA Temp Limit to the level of 90

Over Temp. Alarm

Alarm Reason I: ambient temperature is out of the tolerance of design.

Solution equip an overshadow canopy to avoid the high

temperature caused by the direct sunshine.

Reason and Solution

Alarm Reason II: the environmental condition is air-tighted, so the

heat can not be sent out fluently.

Solution move the repeater to a ventilated location

Set repeater over input power limit at the level of-60dBm

DL Over I/P Alarm

Alarm Reason I: set the DL Over I/P Limit too low

Solution set the DL Over I/P Limit to -30dBm again

Reason and Solution

Alarm Reason II: the signal which the donor antenna received is too strong.

Solution add the attenuator in the input port of repeater or change

the position of donor antenna to adjust the input power of repeater

weak.Solution Change the position of donor antenna and check the

feeder cable which connect to input port of repeater to

increase input power
