Configuration

Power-Saving Master and Controlled outlets

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 turns OFF, the Controlled device(s) will shut down as well, saving electricity.

Disable the Power-Saving feature. Press and hold MUTE and DISPLAY simultaneously for two seconds. The unit will beep to indicate that the feature is disabled. The leaf icon on the display will darken.

Setting the threshold. The amount of power used by a device in Sleep or Standby mode varies between devices. It may be necessary to adjust the threshold at which the Master outlet signals the Controlled outlets to shut down.

2.Press DISPLAY and MUTE simultaneously and hold for six seconds, until the leaf icon flashes three times and the unit beeps three times.

3.The Back-UPS unit will now recognize the threshold level of the Master device and save it as the new threshold setting.
