You will also hear the Channel Free Indication tone if your
call is interrupted, for example when the radio receives an
Emergency Call.
You can turn off the Channel Free Indication tone or the
PTT Sidetone
by disabling all radio tones and alerts
(see Turning the Radio Tones/Alerts On or Off on
page 60).
Switching Between Conventional Analog
and Digital Mode
Each channel in your radio can
be configured as a conventional
analog or conventional digital
channel. Use the Channel
Rocker to switch between an
analog or a digital channel.
When switching from digital to analog mode, certain features
are unavailable. Icons for the digital features (such as
Messages) reflect this change by appearing ‘grayed out’.
Disabled features are hidden in the menu.
Your radio also has features available in both analog and digital
mode. However, the minor differences in the way each feature
works does NOT affect the performance of your radio.
NOTE: Your radio also switches between digital and analog
modes during a dual mode scan (see Scan on
page 26).
Capacity Plus
Capacity Plus is a single-site trunking configuration of the
MOTOTRBO radio system, which uses a pool of channels to
support hundreds of users and up to 254 Groups. This feature
allows your radio to efficiently utilize the available number of
programmed channels while in Repeater Mode.
You can only access channel(s) with Capacity Plus via the
Channel Rocker, while features supported in Capacity Plus can
be accessed via the menu and/or a programmable button press.
Icons of features not applicable to Capacity Plus will not be
available in the menu. You will hear a negative indicator tone if
you access a feature not applicable to Capacity Plus via a
programmable button press.
Your radio also has features that are available in both
conventional digital mode and Capacity Plus. However, the
minor differences in the way each feature works does NOT
affect the performance of your radio.
Check with your dealer or system administrator for more
information on this system.
