Tuning the Radio
Tuning the radio makes it ready to operate using the required waveform, the required settings for the
selected waveform, and at the required frequency. There are three methods of tuning the radio:
(1) Tuning using the current waveform profile. This involves selecting a new operating frequency
while retaining the current operating waveform and radio settings. See page 3-12.
(2) Tuning by recalling a stored waveform profile. This involves recalling one of the 20 available
waveform profiles and then entering the required operating frequency. Waveform profiles are
detailed on page 3-8. Tuning by recalling a stored waveform profile is described on page 3-14.
(3) Tuning by recalling a stored frequency preset. This involves recalling one of the 400 available
frequency presets that have been stored in the radio. A stored frequency preset contains a
Waveform Profile and an operating frequency (or channel if in Maritime mode). Frequency
presets are detailed on page 3-9. Tuning by recalling a stored frequency preset is described on
page 3-17.
Federal Communications Commission (FCC) Regulations
This transceiver complies with Part 15 and Part 87 of the FCC rules. Operation is subject to the
condition that the transceiver does not cause harmful interference.
You are required to obtain a station license before transmitting from your transceiver.
This equipment is licensed only for operation in the VHF aeronautical frequency band between
118 and 136.975 MHz using amplitude modulation (AM) and 25 kHz channel spacing.
The transceiver’s power output should not exceed the output necessary for satisfactory
technical operation, taking account of local conditions and the area to be covered.
The transceiver’s frequency and parameters should be checked by authorized service
personnel before use and yearly (or more frequently) thereafter.
