INDICATORS
Some programmable keys function as toggles 
(alternating between two different choices). These 
keys use audio indicators to indicate the change.
Programmable Buttons
Several of the radio’s buttons can be programmed 
as short-cut buttons for many of the radio’s features. 
Programmable buttons are:
• Top button
• Three side buttons
Check with your dealer for a complete list of the 
functions your radio’s programmable buttons 
support.
The following table shows the functions available by

for a period of time (at least 1.5 seconds) before 
releasing (long press), or by

buttons while checking the status or making 
adjustments.
