3.4.4.3 COM Transmit Power Enablement
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.
NOTE
For first time COM transmit enablement, refer to the
GTN 6XX/7XX AML STC IM, P/N 190-01007-A3, for
additional requirements and checkout procedures. This
manual only describes the necessary steps to re-enable
the feature for existing installations.
1. Turn the GTN off by pulling the NAV/GPS circuit
breaker.
2. Remove the database SD card from the SD card slot
and insert the 16W Enablement Card,
P/N 010-00878-04, that was used at the initial
installation.
3. Enter configuration mode by applying power to the GTN (closing the circuit breaker) while
holding the HOME key.
4. Go to the COM Transmit Power page from the GTN Options page. Touch the 16W key.
5. When the 16W COM feature is activated, the 16W key will be lit green, as shown in Figure 3-15.
NOTE
The feature unlock card should be provided to the customer after service has been
completed.
