2.5 SMARTNET/SMARTZONE FEATURES
2.5.1 INTRODUCTION
The following information describes features
unique to the SMARTNET and SmartZone operating
modes described briefly in Section 2.3.12. Refer to
Section 2.3 for information on features common to all
operating modes, and to Section 2.4 for information on
features unique to the conventional mode.
2.5.2 VIEWING UNIT ID
Each radio in a SMARTNET system is identified
with a system ID and Unit ID. To display the Unit ID,
make sure that a SMARTNET channel is selected and
then turn power off and then on again. The software
version number, current zone, and Unit ID are then
displayed in sequence. The six-digit Unit ID is
displayed as IDxxxxxx.
2.5.3 STANDARD GROUP CALLS
Standard group calls are between you and another
mobile, group of mobiles, or a control station (a radio
at a fixed location). Most calls you make will probably
be this type.
Placing a Standard Group Call
1. Turn power on and set the volume as described in
Section 2.3.2. Select the channel programmed for
the talk group you want to call (see Section 2.3.7).
A regular or announcement talk group can be
selected.
2. Press the PTT switch and when the alert tone
sounds, begin talking. Other indications that may
occur are as follows:
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 the radio system cannot be accessed within 500
ms of pressing the PTT switch, a continuous tone
sounds until the system is accessed or the PTT
switch is released.
If your unit ID is invalid, the call is being made to
an invalid group ID, or group calls are not
allowed, “INVALID ID” is displayed and an alert
tone sounds.
Receiving a Standard Call
Group calls are automatically received if a
SMARTNET/SmartZone channel is selected. The
display continues to indicate the selected channel alias
(name) when a call is received.
2.5.4 ENHANCED PRIVATE CONVERSATION
CALLS
General
Private calls allow you to place a call to a specific
mobile unit. Either the Enhanced Private Conversa-
tion™ or Private Conversation II™ modes may be
programmed depending on the capabilities of the radio
system. The Enhanced Private Conversation mode is
described in the following information, and the Private
Conversation II mode is described in Section 2.5.5.
The Private Call option switch is required to
place these calls, and either that switch or the Call
Response option switch is required to receive them.
Proceed as follows.
Placing an Enhanced Private Conversation Call
This call can be initiated by selecting the unit ID
from a call list (list entry) or by directly entering it
using the keypad (direct entry). Direct entry is avail-
able with full keypad (15-key) models only. Proceed
as follows:
List Entry Method (All Models)
1. With a SMARTNET/SmartZone channel selected,
momentarily press the Private Call option switch.
The private call mode is indicated by “C”inthe
upper part of the display. The tag (alias) of the last

list. Otherwise, the last ID called is displayed.
