• Ensure that the output power of the Adaptor is DC 6V /
6A and that green power LED is illuminated.
• Ensure that all connections are tightly fastened.
• Ensure that the outdoor signal level (RSSI) is sufficient.
(Coiler recommends a signal strength greater than -
80dBm, or three green RSSI LED).
• If external donor antenna is used, ensure that all
connections are tightly fastened.
• Reconnect the power cable.
The signal strength is too weak
in the corner.
• Ensure a strong donor signal level (RSSI) of -80dBm or
better is achieved (three green RSSI LED).
• Adjust the placement location of the PS repeater or
consider using external donor antenna.
• Use the coupler port to install additional service
The repeater’s signal is not stable.
• Ensure that the outdoor signal is stable.
• If external donor/service antenna is used, ensure that
the Isolation LED has five green LED.
• Consider changing location of PS repeater or connect
The red Alarm LED is lit.
• Ensure that input RSSI is not -32dBm or higher.
• If alarm persist even though RSSI is less than -32dBm,
Log into OMT to review the alarms list for exact alarm
