March 2008 5300 ES Series Mobile Radio Operating Manual 3-9
General Operation
The maximum number of channels assignable to a system is limited to 864, depending on
the option enabled. Channels may also be limited by available memory space as described
in the following information.
3.7.4.2 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.
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 approximately 864 channels (depending on the option enabled) can
be programmed with the preceding modes. 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.
3.7.4.3 Zones
A zone is a collection of up to 16 channels of any type. For example, a zone could include
12 conventional channels and four 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 32 or 54 depending on the option enabled.
3.8 Radio Tune Test Mode
This function is primarily used by technical personnel. Entering Tune Test Mode on the
5300 ES radios is done by pressing <F2> during the radio’s self test. If this button is
pressed during the self test, the self test completes and the “SERVICE” message is
displayed.
