2.3 GENERAL OPERATION
2.3.1 INTRODUCTION
This section (2.3) describes features available
with both conventional and SMARTNET/SmartZone
(trunked) operation. For information on features
unique to conventional channels, refer to Section 2.4,
and for information on features unique to
SMARTNET/SmartZone channels, refer to
Section 2.5.
2.3.2 TURNING POWER ON AND SETTING
VOLUME
Power is turned on and off by pressing the On-
Off/Volume switch on the front panel. When power is
initially turned on, an alert tone sounds and the radio
software version is momentarily displayed. The zone
alias is then displayed followed by the unit ID if a
SMARTNET/SmartZone channel is selected (see
Section 2.5.2). The selected channel is then indicated.
When power is turned off, the display may remain on
for a few seconds. It is recommended that power not
be turned back on again until the display is blank.
The volume level is adjusted by rotating the On-
Off/Volume switch. The relative volume level can be
determined by noting the position of the index on the
knob. You may also be able to enable a reference tone
for setting the volume as follows:
•
If key press tones are enabled (see Section 2.3.8), a
short tone sounds when front panel option keys are
pressed.
•
If a conventional channel is selected and the
Monitor option switch is programmed (see Section
2.4.4), pressing that switch unsquelches/squelches
the receiver and either voice or background noise is
heard. If a SMARTNET/SmartZone channel is
selected, the receiver cannot be manually
unsquelched.
2.3.3 BACKLIGHT
The backlight for the display and keypad can be
manually turned on and off if the Backlight option
switch is programmed. Pressing this switch cycles
between the Bright, Dim, and Off modes. If this switch
is not programmed, the backlight is fixed in one of
these modes.
2.3.4 OPTION SWITCHES
All five push-button switches on the front panel
are programmable for the functions indicated in Table
2-1. If your radio is programmed with both conven-
tional and SMARTNET/SmartZone channels (see
Section 2.3.12), these option switches can be
programmed to control a different set of functions for
each channel type. For example, a switch could select
the Monitor Mode when a conventional channel is
selected and Private Calls when a SMARTNET/Smart-
Zone channel is selected. If no option switch has been
programmed to control a particular function, that func-
tion may not be available or in a fixed mode.
2.3.5 CHANNEL AND ZONE SELECTION
Channel Select
To change the selected channel, rotate the Select
switch. The selected channel alias (name) is indicated
on the top line of the display. With conventional chan-
nels, the channel number or frequency may also be
displayed as described in Section 2.4.2.
Zone Select
A zone is a group of up to any 16 conventional
and SMARTNET/SmartZone channels defined by
programming (see Section 1.5.3). Up to 16 zones can
be programmed for a total of 16 x 16 or 256 channels.
One use of zones may be to select groups of channels
programmed for operation in different geographical
areas or radio systems. Zones are selected as follows:
