4. Select the desired system and group. The display indicates the current
system and group names.
5. The radio is now ready to receive calls.
6. When the radio receives a group call, it unmutes on the assigned working
channel and BSY indicator comes on. Line one shows GR followed by
the logical ID number (if received) of the unit sending the message, or
the associated name if the ID number is found in the individual call list.
Sending A Call
1. Turn on the radio and set the POWER ON-OFF/VOLUME knob to the
desired volume level. Select the desired system and group.
2. Press and hold the PTT button. The radio will display the system and
group names and perform the necessary signaling required to obtain a
communication channel.
3. When the working channel is assigned, TX and BSY indicators are
turned on and a short beep sounds indicating that communication can be-
gin. (NOTE: If two or more tones, or a high pitched tone is heard, the
system may be busy and the call request has been placed in queue or the
request has been denied for some reason. Refer to the ALERT TONES
section for more details).
4. Hold the microphone approximately three inches from the mouth and
speak in a normal voice.
5. Release the PTT button when the transmission is complete and listen for
a reply.
Conventional Failsoft
In the unlikely event of a failure of the EDACS System, communications
may take place in conventional failsoft mode. The radio will be automat-
ically directed to a communications channel set up for this purpose. During
this mode of operation, the control unit will display "CONV FS" in the al-
phanumeric display. An increase in activity on the channel during conven-
tional failsoft operation may be noticed, so be careful not to transmit until
the channel is clear.
