Placing a Standard Group Call
1. Turn power on and set the volume as described in
Section 2.4.2. Select the channel programmed for
the talk group you want to call (see Section 2.4.8).
A regular or announcement talk group can be
selected.
2. If encryption is used, it may be automatically
selected. If not, select the secure mode if desired by
pressing the Clear/Secure option switch. Refer to
Section 2.4.13 for more information.
3. Press the PTT switch and when the alert tone
sounds, begin talking. Other indications that may
occur are as follows:
• If in the secure mode and your transceiver does not
have the proper encryption key, “KEYFAIL” is
displayed and the call must be made in the clear
mode (selected by the Clear/Secure option switch
if enabled on the channel).
• 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 3 seconds and begin talking.
• If a continuous tone sounds while pressing the
PTT switch and “NO SYS” 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 call is being made to
an invalid group ID, or group calls are not allowed,
“REJECT” is displayed and an alert tone sounds.
• If an attempt is made to select the secure mode and
there is no available secure channel, “NO SEC” is
flashed and the call continues in the clear mode.
• If an attempt is made to change from the secure to
the clear mode and this is not permitted, “SEC
ONLY” is displayed and the call continues in the
secure mode.
Receiving a Standard Call
When a SMARTNET/SmartZone group call is
received, the transceiver can be programmed to
display the Individual ID of the calling mobile and/or
the received talk group alias. The Individual ID is
briefly displayed when the call is received and the talk
group and channel alias are then alternately displayed
(if applicable).
