BASIC OPERATION
RECEIVE
TURN POWER ON by rotating the OFF-VOL knob clockwise past the Off
detent.
SET VOLUME by pressing the MON button to hear squelch noise. Rotate
the OFF-VOL knob to set a comfortable volume level. Press the MON
button again to stop squelch noise.
SELECT A CHANNEL GROUP (if applicable) by pressing the GRP button and
rotating the Channel Select knob. Press the GRP button again to view the
group label (alphanumeric mode). Press the GRP button one more time or
allow to time out to return to channel select mode. See "GRP" on page 6.
SELECT A CHANNEL by rotating the Channel Select knob. After reaching
the highest channel number, the radio wraps to channel 1.
THE ALPHANUMERIC DISPLAY shows either channel numbers (numeric mode)
or channel labels (alphanumeric mode). The display mode and channel
labels are programmed by the technician along with group labels (if
applicable) and channel frequencies. The display shows slightly different
indications during Channel Scan and Priority Scan operation in
alphanumeric and numeric modes. See the illustrations on pages 10 and
11.
TRANSMIT
PRESS THE PTT (Push To Talk) switch on the microphone. The TX
annunciator appears on the display and the red Transmit Indicator glows
while the PTT switch is pressed. Talk in a normal voice with the microphone
approximately 1 to 2 inches from your mouth. Release the PTT switch to
stop transmitting.
If the TX annunciator does not appear and a tone is heard, you are on a
receive-only channel or the channel is busy (only if Busy Channel Lockout
is installed). Turn the Channel Select knob to an authorized transmit
channel or wait until the channel is clear (if Busy Channel Lockout is
installed).
If the length of your message exceeds the preset time out timer
setting, the Transmitter automatically shuts off and a tone is heard. To
continue the transmission, release the PTT switch, then press it again and
continue talking.
