• If your unit ID is invalid, the call is being made to
an invalid group ID, or group calls are not enabled,
“DISABLED ID” is displayed and an alert tone
sounds.
• If an attempt is made to change an analog channel
from the clear to 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 and analog channel
from the secure to the clear mode, “SEC ONLY”
is displayed and the call continues in the secure
mode. (Calls on digital channels can be changed if
they are not fixed in the clear or secure mode.)
• If the Secure mode is selected by the Secure/Clear
option switch and an attempt is made to transmit
on a channel fixed as Clear, “Clear Only” is
displayed and the transmitter is disabled. Like-
wise, “Secure Only” is displayed when attempting
to transmit in the Clear mode on a channel fixed as
Secure.
Receiving a Standard
Group Call
Group calls are automatically received if a
SMARTNET/SmartZone channel is selected. The
display alternates between the selected channel tag
(alias) and the received talk group tag. The transceiver
may also be programmed so that the individual ID of
the mobile placing the call is briefly displayed before
this information.
5.4 PRIVATE (UNIT) CALLS
NOTE: With P25 Trunked operation, these calls are
called Unit Calls.
5.4.1 GENERAL
Private calls allow you to place a call to a specific
mobile unit. With SMARTNET/SmartZone operation,
Either the Enhanced Private Conversation™ or Stan-
dard Private Conversation mode may be programmed
depending on the capabilities of the radio system. With
P25 Trunked operation, Unit Calls operate the same
as the Enhanced Private Conversation mode.???
Operation in both the standard and enhanced
modes is described in the following information. The
CALL option switch is required to place these calls,
and either that switch or the
RESP (Response) switch
is required to receive them. Proceed as follows.
5.4.2 PLACING AN ENHANCED PRIVATE CON-
VERSATION CALL AND P25 UNIT CALL
1. Momentarily press the CALL (Private/Unit Call)
option switch. The tag (alias) of the last called
mobile is displayed.
2. To select another mobile, rotate the Select switch
until the alias for the desired mobile is displayed.
3. Press the PTT switch and one of the following
events then occurs:
• If the mobile being called is on the air, “WAIT” is
displayed and ringing is heard until the called
party answers or for 20 seconds, whichever occurs
first. Pressing the PTT or an option switch stops
the ringing but not the call. When the call is
answered, the voice of the called party is heard.
• If the called mobile does not answer within 20
seconds, a continuous tone sounds and “NO ANS”
is displayed.
• If the called mobile is not on the air, a continuous
tone sounds instead of the ringing tone and “NO
ACK” is displayed.
• If the busy tone sounds and “BUSY” is displayed,
the called mobile has answered the call but the
system is busy. When the system is no longer busy,
the call back tone sounds.
• If your transceiver or the called transceiver is
inhibited or not programmed to make this type of
call or for the requested secure mode, “RSPNS
ONLY” is displayed and an alert tone sounds.
• If your transceiver does not have the proper
encryption key, “KEYFAIL” is displayed and the
call must be made in the clear mode by pressing
the
C/S (Clear/Secure) option switch (if encryp-
tion is selectable on the channel). Otherwise, the
correct key must be loaded.
