Channel Selection
English
The GM950 is a highly flexible mobile radio and can
be configured in many ways to best match your
specific operational requirements. The following
information describes typical operation. Please
contact the person in charge of your radio system
or your local Motorola representative for further
information.
Channel Selection
4-Channel Model
To select a channel, press one of the four channel
select buttons (7) for the desired channel. If the
channel is available, the green, channel-selected LED
(8) will light. If it is not, the error tone will sound.
128-Channel Model
To select a channel, enter channel mode
(
displayed) by pressing channel select button
(9c), then use the up/down scroll buttons (7) to
display the desired channel number. The channel
may be used as soon as it is displayed.
Channel Without Selective Call Functions
When you have selected a channel, you are ready
to transmit. You should only make a call when the
channel is free ( red indicator (4) does not flash). If
in doubt, press the monitor button (5) to listen to the
channel.
Communication Procedures
Take the microphone out of its holder. Press the
transmit (PTT) key (11) on the side of the
microphone while talking, release it while listening.
Speak in a normal tone of voice, keeping a distance
of 5-10 cm from the microphone. When transmitting
the red indicator (4) will light continuously. Your
radio may be configured for ‘Transmit Inhibit’ under
certain conditions (e.g. when the channel is in use
by other users) in which case, the channel busy
tone will sound when you press the PTT key to
indicate that transmission is inhibited.
If your radio is equipped with a transmit time out
timer (TOT), a warning tone will sound a few
seconds before the transmission is cut off. The
radio may be programmed to inhibit retransmission
within a preset time.
Call Termination
Hang up the microphone in its holder when your
conversation has ended.
