Ericsson LBI-38823C - Manual (Page 42)

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 absence of the "BSY" indicator to ensure
that no one is transmitting on the selected Group.
3. Press and release the PTT bar. The radio will perform the necessary
signalling required to obtain a communication channel.
The radio is out of range or the radio is inoperative when the signalling
is unsuccessful, the "NO" and "SV" indicators are illuminated and a
sequence of five beeps are heard at the speaker. Any subsequent
attempt to initiate a call within the next 20 seconds will be ignored. The
radio can be cleared from this mode by double clicking the SHFT/CLR
button.
All channels are busy when the signalling is unsuccessful and a one
second low frequency tone is heard at the speaker. The call will not
be retried automatically.
4. When the channel has been acquired, the "BSY" flag is illuminated
and the Call Originate tones (three tone alert) will sound.
5. Press PTT bar. The "TX" flag will illuminate. Hold the radio about
three 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.
SENDING A SPECIAL CALL
If the "Call Retry" option is active, the radio will try the channel at
twenty second intervals for five minutes before returning to the
normal System/Group display.
