Backlight Timer; Figure 9. Brightness And Contrast Screen - Audiovox Satellite Radio Receiver User Manual

to a minimal level.

Backlight Timer

The Backlight Timer feature allows the user to set the amount of time the
display backlight is turned on, or the period before the display darkens,
provided no other button has been pressed during the selected time-out
interval; time increments of 10, 20, and 30 seconds are presented for
selection at your discretion. This user-friendly option subdues the
display during sleep hours or other particular periods.
