Preventative Maintenance of the Radio

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 132 of the MICOM-2E/2R User’s Guide.
