7.3 Standard Group Calls
Standard calls are between you and another mobile, group of mobiles, or a control station
(a radio in a fixed location). Most calls are probably this type. Proceed as follows to place
and receive group calls.
7.3.1 Placing a Standard Group Call
To place a Standard Group Call:
1 Turn power ON and set the volume as described in Section 4. Select the channel
programmed for the talkgroup you want to call (see Section 4.1.6.3).
2
If the talkgroup is programmed for encryption and is not strapped to Clear or Coded,
select the desired mode by pressing the C/S (Clear/Secure) option switch or selecting
the menu parameter. The status of that switch is ignored if the talkgroup is strapped to
Clear or Coded. Refer to Section 8.3 for more information.
3 Press the PTT switch and begin talking. An optional talk permit tone may sound to
indicate when talking can begin. Other indications that may occur are as follows:
- If in the secure mode and your radio is not programmed with the proper encryption
key, “KEYFAIL” is displayed and the call must be made in the clear mode or the
proper key must be programmed.
