the system and site name.)

can be restored by pressing any button.

GROUP 2—CONFIGURATION

Access Level

This screen is used to set the front panel display to conﬁguration mode by selecting

a level of access. There are two levels:

NONE—This is the default setting upon power-up (“safe” mode). All radio set-

tings can be viewed, the access level can be changed, and the front panel dis-

play brightness and contrast can be changed. All other settings are for display

only, and cannot be changed.

USER—Changes can be made 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 has elapsed without a button press, or if the radio is powered off and then

on.

Transmit

Frequency

This screen is used to display or set the transmitter frequency.

Normally, the radio will be shipped programmed with the customer-speciﬁed

frequency. If the operating frequency was not speciﬁed when the radio was

ordered, the TX frequency is set to the center of the radio’s operating band. The

range of frequencies for standard models are given Section 10.1, Technical

Speciﬁcations, beginning on Page 93.

To change the current frequency, press ENTER, then use the left/right arrow

buttons to select a digit. Then use the up/down arrow buttons to increase or

decrease the number. Press ENTER to make the change.
