Start-up Screen
When the radio first powers on, or after a period of time has elapsed after the last

customers use the owner name and message fields to display the system and site
name).
The screen dims after a period of time has elapsed without activity; restore
brightness by pressing any button.

GROUP 2—CONFIGURATION
Access Level
Use this screen to set the front panel screen to configuration mode by selecting a
level of access. There are two levels:
NONE
—This is the default setting upon power-up (“safe” mode). You can view
all radio settings, change the access level, and change the front panel screen’s
brightness and contrast. All other settings are shown only, and cannot be
changed.
USER
—Make changes to any radio parameter (“configuration” mode).
To select the
USER
access level, press ENTER, press the down arrow button to
display the word “User,” then press ENTER again to make the change.
The radio returns automatically to safe mode (access level:
NONE
) after a period
of time without a button press, or if the radio is powered off and then on.
Transmit
Frequency
Use this screen to set or show the transmitter frequency.
Normally, the radio ships configured with the customer-specified frequency. If you
did not specify the operating frequency when the radio was ordered, the factory
sets the TX frequency to the center of the radio’s operating band. The range of
frequencies for standard models are provided in
Section 10.1,
Technical
Specifications, beginning on Page 97
.
To change the current frequency, press ENTER, then press the left/right arrow
buttons to select a digit. Use the up/down arrow buttons to increase or decrease
the number. Press ENTER to make the change.
