PRESET CHANNEL
PROGRAMMING INSTRUCTIONS
Turn the equipment On by rotating the MAIN ON/OFF volume
control clockwise. Aircraft or vehicle power must be available to
the unit by operating the appropriate switches and/or circuit
breakers.
To hear the audio, the appropriate audio select switches, if any,
must be in the proper position and the volume control set to the
appropriate level. The volume level can be tested setting the
background noise level generated when the TEST/LOAD button is
depressed.
NOTE: To optimize system performance, allow five minutes for
warm-up. Two and one-half minutes warmup is required to insure
the transmitter frequency is within the FCC requirements.
The programming procedures described in detail in the following
steps consist of
(1) Selecting the channel to be programmed.
(2) Setting up the channel frequency, tone and narrow/wide band
mode if the unit has the narrow band modification.
(3) Selecting receive or transmit with the PRESET switch.
(4) Pressing the TEST/LOAD Button while holding the PRESET
switch.
(5) Verification of proper load.
NOTE: Internal switches are provided to prevent control unit
programming or manual transmit frequency selection by operators
not having an FCC second class, or higher, commercial operator
license.
MAIN RCV/XMT FREQUENCY
1. Select the desired channel (page and number) to be
programmed on the channel selectors.
2. Set up the XMT frequency and CTCSS tone on the

the OFF position. To choose the proper tone code to be used,
refer to the Tone Selection Chart. If the unit has the narrow
band modification, set the N/B switch to the desired setting.
3. Set the T/R - MAIN/BOTH/GUARD to MAIN.
4. Operate the PRESET switch to the XMT position and hold.
5. Push and release the LOAD button. The XMT frequency is
now loaded for the selected channel.
6. Set up RCV frequency and CTCSS tone on the Thumbwheels.
7. Operate PRESET switch to the RCV position and hold.
