Maintenance
No special maintenance program is required for the APM or frequency banded Couplers.
Firmware upgrades may periodically be made available and will require uploading into the APM.
Physically checking that the 7/16DIN (M) RF connectors on the feeder cables from the combiner and to the antenna are correctly
torqued (as per manufacturers recommendations) onto the corresponding Coupler termination connectors is considered good
practice. All N Male termination connectors on the RF coaxial connectors on both the APM and Coupler/s must also be tightened.
The 2-pin Phoenix DC connector socket must be firmly located and pushed into the corresponding power plug on the APM.
Neither the APM nor the Coupler/s are considered field repairable and should it be considered that either unit may be faulty
through diagnosis, they will have to be returned to RFI.
