Controls
Buttons
Power: The power button is the “on-off” switch for the handset. It is a
“delayed action” button – you must keep it pressed for a second or two
and then release it to initiate the power on or power off sequence. When
pressed briefly, this key is used to end a telephone call. It is also used as
a Quick Exit from any menu through which you are navigating. When you
press the key, you are returned to the “idle” display screen.
PTT: Pressing and holding the PTT button initiates and maintains a
Dispatch Radio call.
P1: Pressing this key initiates a Priority-1 Emergency Interruption
Dispatch Radio call.
Physical Keys
Keypad Keys: The keypad contains alphanumeric keys for text entry and
Voice number dialing.
Send: This key is used to initiate a telephone call and Dial-Out Dispatch
sequence.
Up Arrow/Down Arrow: These keys are used primarily for the following
functions:
• Volume adjustment
• Scrolling through various menus
• Scrolling through downloaded talkgroup 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 talkgroup 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.
Summary of SK1 functionality:
• Menu – used to access various user menus. The “Menu” soft key
indicator is displayed when the radio is in an idle state.
• Clear – used mainly while in editing mode (labeling talkgroup tag
positions, labeling GPS positions, etc.). A single press deletes a
single character; press and hold will delete 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
serial port configuration.
