DISPATCH MODE OPERATION INDICATORS
Tag Position (i.e. 01:XXXXXXX )
Once a talk group is successfully downloaded, an associated two digit tag
number is assigned by the Network and appears on the display screen. A radio
can have up to 16 tag positions (including tag 00 for private mode operation).
BX SXX
This indicator specifies the beam to which the radio has logged-on, as well as
the radio received signal strength (i.e. B1 S55). Beam mapping is as follows:
Beam 0 East
Beam 1East Central
Beam 2 West Central
Beam 3 West
Beam 4 South
Beam 5 Alaska/Hawaii
Signal strength ranges from 0 (no signal) through 99.
NO TG
This indicator appears in the event that a talk group has not yet been
downloaded to the radio.
TG UPDATE
This indicator appears when a talk group has been successfully downloaded to
the radio, reconfigured or deleted from the radio over the air. Talk groups
download quickly when the radio is powered on. If the configuration of talk
groups is changed at the network while the radio is off, the talk group
information will be downloaded via the signaling channel when a call is made
or a manual beam cross-over is initiated.
DR
This indicator appears when the radio is in idle state in Dispatch Radio mode.
IN USE
This indicator appears when a Dispatch Radio call is in progress. It will remain
until the call has been terminated.

UP ARROW/DOWN ARROW: These keys are used primarily for the
following functions:
Volume adjustment
Scrolling through various menus
Scrolling through downloaded talk group tag positions
In certain contexts, the Up/Down arrows also serve as “soft keys.”
SOFT KEYS
Four “soft keys” are used to enable the following functions:
Navigation through Menus
Storage of data in the radio
Selection of Dispatch Radio talk group tag positions
Activation/Deactivation of various functions and features
These keys are called “soft keys” because the way they work depends on the
context of the function currently being exercised on the handset. A soft key
“label” is shown above the key in the display area.
Soft Key 1 (SK1): This key is located just below the display area and just
above the SEND key. Its label is shown directly above it in the display area.

indicator is displayed when the radio is in an idle state.
CLEAR – used mainly while in editing mode (labeling talk group tag
positions, labeling GPS positions, etc.). A single press deletes a single
character; press and hold deletes the entire line of text.
BACK – used to back out of a given menu. This key generally brings
you to the previous menu option without implementing changes (e.g.
number storage, volume level setting, etc.) you made on the current
menu.
EXIT – used to exit the main user menu section. This key takes you
back to the default screen display.
NO – this key only appears when you attempt a manual beam cross-
over, attempt to abort the commissioning process, or change the
