6 - Enter and store the transmit frequency.
Use the outer larger concentric knob to position the flashing
“cursor” on each digit of the transmit frequency and use the smaller
inner knob to select the desired number in each position.
7 - Store the transmit frequency.
Push the STO button again and the transmit frequency is now
stored. If additional user channels are to be programmed, repeat
steps 2 through 7 at this time.
8 - Exit the program mode
Press the PGM switched with pointed object.
9 - Tune the antenna.
Momentarily key the PTT to initiate the antenna coupler tuning
cycle. Adjust the volume (V) and squelch (S) controls, as desired.
SIMPLEX CHANNEL PROGRAMMING PROCEDURE
When you program a channel for simplex operation, both the receive
and the transmit frequencies will be the same. Programming a simplex
channel is similar to programming a semi-duplex channel, except the
STO button is pressed twice after the receive frequency and mode of
operation are entered to store the frequency in both the receive and
the transmit positions.
RECEIVE-ONLY CHANNEL PROGRAMMING PROCEDURE
1 - Access channelized and program mode.
Apply power to the system by rotating the VOLUME (V) knob
clockwise from the OFF position. Make sure that the FREQ/CHAN
button is pressed, in the CHAN position. Activate the program mode
by pressing the PGM switch with a pointed object.
2 - Stow the cursor.
Stow the “cursor” if a frequency digit is flashing. The cursor is
stowed by rotating the larger concentric knob until no frequency
digit is flashing. With the cursor stowed in the program mode, the
smaller inner knob is now used to select a channel number to be
programmed.
