When an internal problem appears or is suspected, the MICOM-2E
internal BITE will assist the user to locate the source of this possible
problem and inform the service shop or dealer accordingly.

Preventive Maintenance

System Integrity

Periodically check the integrity of your system, check the power source,
cables, coaxes, connectors, antenna tuner (if exists) and antenna.
Carefully check that no damage has been caused to your cables, pay
extra attention to runway through holes and bent cables.
