Using the Bose® power pack or Bose DC power cord accessory, you can operate your Acoustic Wave® music system II on 12-volt DC power. The 12-volt DC input jack is located on the rear panel to the left of the AC input jack.
Operating on DC power causes some changes in operation:
- The display backlight is normally off. Pressing any control panel button turns on the backlight for a few seconds
- CD source only: If a disc is playing continuously, the system automatically turns off after 24 hours with no user interaction
