POST-INSTALLATION CHECKOUT
After Airtext is installed, complete the checkout procedures herein to verify proper basic operation.
Mounting, Wiring, and Power Checks
Check that Airtext is mounted rigidly. Do not connect Airtext to the aircraft harness until the following
checks have been performed:
1. Check that all cables are properly secured and shields (if used) are connected at one end only. Either to
the shield block of the connector at the Airtext router, at ONE of the disconnects, or at the far termination
of the cable. Check the movement of the flight and engine controls to verify there is no interference
between the cabling and control systems.
2. Prior to powering up Airtext, check the wiring harness for point to point continuity to expose any faults
such as shorting to ground or swapped pins. Any faults or discrepancies must be corrected before
proceeding.
3. After accomplishing a continuity check, perform power and ground checks to verify proper power
distribution to Airtext. Any faults or discrepancies should be corrected at this time. Remove power from
