What to do if COMBA Repeater shows DL Input Power Overload Alarm?
To address a DL Input Power Overload Alarm on your COMBA Repeater, first, adjust the input power overload threshold settings. Then, verify that the signal source intensity is adequate. If the alarm persists, further equipment inspection is necessary.
What to do if COMBA Repeater displays DL Output Power Low Alarm?
To resolve a DL Output Power Low Alarm on your COMBA Repeater, try the following: start by resetting the output power low threshold. If the problem persists, adjust the ATT value to increase the Gain. Also, ensure that the Channel No. setting is correct and verify all cable connections. If these steps don't clear the alarm, the equipment needs to be checked.
How to fix Device Over-temperature Alarm on COMBA Repeater?
To fix a Device Over-temperature Alarm on your COMBA Repeater, begin by adjusting the temperature threshold settings. If the alarm continues, consider applying climatic protection to the equipment.
What to do if COMBA Repeater shows UL/DL PLL Alarm?
To troubleshoot a UL/DL PLL Alarm on your COMBA Repeater, first, check the Integrated Module’s power and wire connections. If the connections are secure, consider replacing the Integrated Module.
What to do if COMBA Repeater shows AC Power Failure Alarm?
If your COMBA Repeater is showing an AC Power Failure Alarm, check the AC power cable and ensure the AC mains supply is working correctly. Note that during a power failure alarm, the DC power supply will not have any output.
