7. The unit returns to normal operation if no failures are detected and a "System Test Pass" message is
heard through the aircraft audio system.

A "Fail" indicates an internal unit error. Refer to the fault isolation information provided in the
maintenance manual for detailed information.
An "External Fail" indicates an external signal loss. Check antenna and data source signals and
connections. Refer to the fault isolation information provided in the maintenance manual for
detailed information.

No TIS-B Coverage Indicator, located on the traffic screen next to the zoom out button, may be
seen due to the unit being out of range of a ground station. This is normal and the checks may
proceed.
If the problem is persistent, it may be necessary to connect the MPC and use the MPC (MAT) to
