5. Using the VOLUME buttons, adjust the volume as necessary.
SENDING A MESSAGE
1. Turn the radio on and set the desired System and Group as described
under RECEIVE A MESSAGE steps 1-3.
2. Observe the display for the presence of the "SV" flag for service and
the absence of the "BSY" indicator to ensure that no one is transmitting
on the selected Group.
3. Press and hold the PTT bar. The radio will perform the necessary
signalling required to obtain a communication channel. If the signalling
is unsuccessful, the radio will sound the appropriate alert tone(s).
4. When the channel has been acquired, the "TX" and "BSY" flags are
illuminated and if programmed, the Call Originate tone will sound.
5. Hold the radio about 3 inches from your mouth and speak as you would
normally into the microphone.
6. Release the PTT bar when the transmission is complete and listen for
any reply.
SQUELCH ADJUSTMENT
In normal operation the squelch is automatically set by the radio and
does not need adjusting. If it becomes necessary to adjust the squelch, the
squelch may be adjusted using the following procedure:
The radio must be on a Conventional System or an EDACS working
Channel (i.e. receiving a voice call) to adjust the squelch. It is
recommended to adjust squelch from a Conventional System.
