Auto-Off / Sleep Timer
This feature allows the user to program the Xpress XM® unit to
automatically shut OFF if the unit remains in an inactive state for a
period of time ranging between 15 Minutes and 3 hours (see Figure
37). There are 6 available settings:
· 15 Minutes
· 30 Minutes
· 45 Minutes
· 1 Hour
· 2 Hours
· 3 Hours
This feature is useful in preventing the vehicle battery from draining in
cases where the unit is installed with a constant power source. It is also
useful as a Sleep Timer turning the unit OFF automatically after a
period of time.
When in the Auto-Off / Sleep Timer mode use the Rotary/Select Knob
or the Remote Control UP and DOWN buttons to highlight one of the six
(6) time settings you wish to select.
When the desired time setting is highlighted, press the Rotary/Select
Knob, or the remote’s (XM) select button to enter your selection.
Acceptance is confirmed by an audio beep and confirmation screen.
