Making changes to radio functions
1. When an individual menu screen is displayed, press the
ENTER
button. The message
change pending appears at the bottom of the
screen. This tells the system that the next series of arrow button
presses are to make on-screen selections, not display menu screens.
2. Most options are either words (“enabled,” “disabled”) or numbers.
The instructions below apply in most situations; if not, the method
for choosing an option is detailed in the screen description.
Word options. To display all choices when the options are words,
press the up or down arrow button.
Numeric options. If the option is more than one digit, first select the
digit to change: press the left or right arrow button to move
the underscore cursor ( _ ) under the digit to be changed. (For exam-
ple, to change “30” to “40,” move the underscore under the “3.”)
Then press the up or down arrow buttons to increase or
decrease the number. Or hold down the arrow button to scroll
choices more rapidly.
3. Press the
ENTER button again when the desired choice is displayed.
(Or press the
ESCAPE button to cancel the change.) The message
done appears, indicating that the change was successfully made.
