only. Rotate the Select switch to toggle between
“WIDE” and “NARROW”, and when the desired
setting is displayed, store it by pressing the Select
switch.
SQ ADJUST (Analog Only) - Changes the preset
squelch setting on that channel. The default setting is
“0” and values of –7 to +7 can be selected. Increasing
this setting toward +7 causes the squelch to open
sooner so that weaker signals can be received, and
decreasing it toward –7 causes the opposite to occur.
TG ID (P25 Only) - Selects the talk group for the
selected channel. Rotate the Select switch to display
the alias of each preprogrammed talk group and then
press it to store the desired talk group.
SECTION 5 SMARTNET/SMARTZONE/P25 TRUNKED FEATURES
5.1 INTRODUCTION
An overview of the SMARTNET/SmartZone and
P25 trunked operating modes is located in Section
3.19.3. The following information describes the
features unique to these modes of operation. Refer to
the “General Operation” section starting on page 9 for
information on features common to all operating
modes.
5.2 VIEWING UNIT ID
When power is turned on with a SMARTNET/
SmartZone trunked channel selected, the 5-digit Unit
ID is briefly displayed as IDxxxxx. When a P25
channel selected, the 8-digit unit ID from
1-16,777,216 is displayed (see Section 4.13.1).
5.3 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 these calls.
A SMARTNET/SmartZone channel may be
programmed with a Talk Group and/or Announce-
ment Group ID plus an Emergency ID. When a call is
received on a channel programmed with both Talk and
Announcement groups, only the Talk and Announce-
ment group IDs are detected. Other IDs in the
Announcement group are detected only if no talk
group is programmed. The emergency ID is used for
the emergency alarm and call (see Section 5.9).
Proceed as follows to place and receive group calls:
Placing a Standard Group Call
1. Turn power on and set the volume as described in
Section 3.1 on page 9. Select the channel
programmed for the talk group you want to call (see
Section 3.6 on page 10). A regular or announcement
talk group can be selected.
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.
The status of that switch is ignored if the talk group
is strapped to Clear or Coded. Refer to “Secure
Communication” on page 16 for more information.
3. Press the PTT switch and begin talking. A 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 transceiver 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.
• 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.
• If a continuous tone sounds and “NO SYS” is
displayed, you may be out-of-range. Drive closer
or away from shielding objects and try again.
