Version 16.10 AF-6600 AF-5000 Series Install Manual 75
Post Installation Checks
Ground Tests
1. Do all AF-COM-T25 buttons and knobs function normally?
2. Does the (optional) FLIP/FLOP pushbutton swap the STBY and COM frequencies?
3. Does pushing the PTT switch cause the AF-COM-T25 to transmit (only) when pushed? DO NOT
TRANSMIT WITHOUT AN ANTENNA CONNECTED. DOING SO WILL DAMAGE YOUR AF-COM-T25 RADIO.
5. Temporarily install a VSWR meter between the AF-COM-T25 and the antenna. Using brief test
transmissions, is the VSWR 3:1 or below? The maximum acceptable VSWR for A SV-COM-T25 is 3:1.
6. When transmitting on SV-COM-T25, is there any interference to other aircraft systems?
7. Power off the AF-6600 / AF-5000 display(s). The SV-COM-T25 should continue to operate normally,
with the exception that auto-population of frequencies will not occur, and a NO SV error message will
appear approx. 3 seconds after SV is not operating.
In Flight Tests
1. Does the AF-COM-T25 receive other aircraft and ground transmissions at reasonable ranges?
2. Is received audio clear at most volume levels on the AF-COM-T25? (Distortion at high volume levels
is normal.)
3. Are transmissions from the AF-COM-T25 heard by others at reasonable ranges? (Keep in mind that
the power output of the AF-COM-T25 is 6 watts.)
4. Are transmissions from the AF-COM-T25 clear (when received by others)?
