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.

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. When the threshold is set,
the power-saving outlets are enabled.
1.Ensure a master device is connected to the Master outlet. Put that device into Sleep or Standby mode, or turn it
OFF.
2.Press and hold the Master Enable button for six seconds. After the first 2 seconds the unit will beep, continue
holding the button down until the unit three beeps times in a row. Release the Master Enable button.
The Back-UPS unit will now recognize the threshold level of the Master device and save it as the new threshold
setting.
