6.4 Configuration and Programming using the
Front Panel
If you cannot connect a PC running GE MDS diagnostics software to the
radio, use the front panel display and controls to review and change
operating parameters and perform diagnostics. This section explains
how to use the front panel controls and screens. Cross-references to the
corresponding PC-based commands are included.
The front panel display has two modes: "safe" mode (display only), and
configuration mode. These modes are changed by defining the user
access level. When the radio is powered on, the front panel display is in
safe mode. The front panel display mode, and the brightness and con-
trast of the front panel display, are the only changes that can be made to
the radio in safe mode. The front panel display reverts to safe mode after
a period of time has elapsed without a button press, whenever the radio
is powered back on, and whenever a switchover occurs.
Normally, if no button activity occurs for one hour, the LCD display
reverts to a power saving mode. The only exception is the Operating
Status screen. This is a special screen, found under the Diagnostics main
menu. This screen displays key status, RSSI, and SNR (if applicable).
The screen does not time-out, and is preserved during power outages
and radio switchovers.
Changing the front panel display to configuration mode is described in
"Switching the Front Panel Display to Configuration Mode" on Page

tions. Individual screens are described in more detail in
