NOTE
This manual only describes the necessary steps to re-enable the 16W COM transmit power
for existing installations. For first-time 16W COM transmit power enablement, refer to the
GTN 6XX/7XX Part 27 AML STC IM.
NOTE
The 16W COM Transmit Feature Enablement Card should be provided to the customer
after service to the GTN has been completed.
When the optional 16W COM power is configured, the GTN COM will transmit with 16 watts rather than
the standard 10 watts. This section describes how to re-enable the 16W COM transmit power:
