6.3 Standard Group Calls
Standard group calls may be placed to another radio, group of radios, or a dispatcher,
depending on programming. Most calls are probably this type. Proceed as follows to place
and receive group calls.
6.3.1 Placing a Standard Group Call
1 Turn power on and set the volume as described in Section 3.1. Select the channel
programmed for the talk group you want to call (see Section 3.3).
2 If the talk group is programmed for encryption and is not strapped to Clear or Coded,
select the desired mode by pressing the Clear/Secure option switch or selecting that
menu parameter. The status cannot be changed if the talk group is strapped to Clear or
Coded. Refer to
Section 10.3 for more information.
3 Press the PTT switch and begin talking. An optional talk permit tone may sound to
indicate when talking can begin. Events 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.
The user hears the key fail tone, and will not be allowed to transmit until secure
mode is disabled or the proper key is loaded to the radio.
- If the busy tone sounds and “Busy” is displayed, the system is busy. Release the PTT
switch and wait for the call back tone to sound. Then press the PTT switch within
three seconds.
- If a continuous tone sounds and “Out of Range” is displayed, you may be out-of-
range. Drive closer or away from shielding objects and try again.
- If your unit ID is invalid, the radio will not affiliate and is denied system access if the
Unit ID is not displayed on system.
- If an attempt is made to change an analog call from the clear to secure mode and there
is no available secure channel, “No Sec” is flashed, an error tone sounds, and the call
is terminated.
- If an attempt is made to change an analog channel from the secure to clear mode,
“SEC ONLY” is displayed, an error tone sounds, and the call is terminated. (Calls on
digital channels can be changed if not strapped to clear or secure.)
- If the secure mode is selected by the Secure/Clear option switch or menu parameter
and an attempt is made to transmit on a channel strapped as clear, “Clear Only” is
displayed and the transmission is denied. Likewise, if the clear mode is selected and
the channel is strapped as secure, “Secure Only” is displayed and the transmission is
denied.
