Maintenance
Introduction
This section provides maintenance information for the user of the MICOM-3 radio. By carrying out
the installation procedures correctly and following the maintenance instructions properly, you ensure
continuous operation of your radio set.
When an internal problem appears or is suspected, the MICOM-3 internal BITE (built-in test
equipment) will assist you in locating the source of this possible problem to inform the service
representative accordingly.
Preventative Maintenance
System Integrity
Periodically check the integrity of your system: check the power source, cables including coax cables,
connectors, antenna tuner (if used) and antenna.
Carefully check that no damage has been caused to your cables; pay extra attention to runway
through holes and bent cables.
Periodic Calibration
To keep the frequency accuracy of your radio, it is required to calibrate its internal frequency source
after 3, 6 and 12 months of operation during the first year, and once a year thereafter. Please ensure
that your radio is calibrated on time.
