Channels
A channel selects a radio (RF) channel or talk
group as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, Call Guard (CTCSS/DCS)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NAC squelch coding, talk
group ID, and other parameters unique to that channel.
Mode - A channel selects a specific talk group ID and
other parameters unique to that talk group.
SMARTNET/SmartZone and Trunked Project 25
Modes - A channel selects a specific talk group,
announcement group, emergency group, and other
parameters unique to that talk group.
A maximum of up to 512 channels can be
programmed with the preceding modes (with the 512-
channel option). These channels can belong to a single
system or multiple systems. The maximum number is
also limited by the available memory. For example,
since more memory is required to program a
SMARTNET system than a conventional system, the
total number of channels decreases as the number of
SMARTNET channels increases. The programming
software displays a bar graph which shows the amount
of available memory space that is used by the current
data.
Zones
A zone is a collection of up to 16 channels of any
type. For example, a zone could include 12 conven-
tional channels and 4 SMARTNET channels. One use
of zones may be to program the channels used for
operation in a different geographical areas. The
maximum number of zones is limited to 16 with stan-
dard models or to 32 with the 512-channel option.

4.1 OPTION SWITCHES
Almost all the buttons on this transceiver are
programmable. The programmable switches are as
follows:
• On the side panel, the three switches above the PTT
switch (see Figure 2-2 on page 12).
• On the top panel, the rotary three-position switch
and the orange switch (see Figure 2-1 on page 11).
• On the front panel, F1 and F2 unless the menu mode
is used (see next section), and F3 and F4.
• With DTMF keypad models, all 12 DTMF keys.
The functions that can be controlled by option
switches are shown in Table 4-1. Each option switch
can be programmed to control a different function in
each of the three operating modes. For example, F3
can control one function when a conventional channel
is selected, another when a SMARTNET/SmartZone
channel is selected, and still another when a Project 25
trunked channel is selected.
4.2 MENU MODE
Most functions that can be controlled by an
option switch can also be controlled by the menu
mode. The functions that can be controlled by the
menu mode are shown in Table 4-1. Functions can be
controlled by both an option switch and a menu
parameter if desired.
Menu Mode Buttons
When the menu mode is used, the F1 and F2
switches become dedicated menu mode control
