Maintenance
This section provides maintenance information for the MICOM-H. Correct
installation and maintenance will ensure on-going operation of your radio set.
If an internal problem is suspected, the BITE (Built In Test Equipment) will assist you
in locating the source of the problem and in informing your service representative.
Preventative
Maintenance
System Integrity
Periodically check the integrity of your system, by examining the power source,
cables, coaxes, 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 maintain the frequency accuracy of your radio, the internal frequency source must
be calibrated after 3, 6 and 12 months of operation in the first year, and once a year
thereafter. Please ensure that your radio is calibrated on time.
Using BITE
Every time the radio is turned on, a self-test procedure is activated. If an internal
malfunction is found, an error message will be displayed. Please contact your service
representative and report the indicated malfunction or error. A list of possible error
messages is given on page 48.
