To conserve electricity, configure the Back-UPS to recognize a Master device, such as a desktop
computer or an A/V receiver, and Controlled peripheral devices, such as a printer, speakers, or a scanner.
When the Master device goes into Sleep or Standby mode, or is switched OFF, the Controlled device(s)
will be switched off as well, saving electricity.

Back-UPS will beep to indicate that the feature is enabled. The leaf icon on the display will illuminate.
Disable the Power-Saving function. Press and hold MUTE and DISPLAY simultaneously for two seconds. The

OFF.
2. Press
