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.
Here is a 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 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 serial port
configuration.
• GPS – used to activate/deactivate the GPS information indicator on
the handset display screen. This soft key appears during a call.
