On Line (green) - is illuminated whenever AC utility power is supplying power the outlets.

Overload (red) - is illuminated whenever power demand has exceeded the capacity of the Back-UPS.

Continuous Tone - this alarm is sounded whenever the Back-UPS outlets are overloaded.

On Battery (yellow) - is illuminated whenever the Back- UPS battery is supplying power to the equipment connected to the outlets.

Four Beeps Every 30 Seconds - this alarm is sounded whenever the Back-UPS is running On Battery. Consider saving work-in-progress.

Continuous Beeping - this alarm is sounded whenever a low battery condition is reached. Battery run-time is very low. If supplying power to a computer directly from the Back-UPS, promptly save any work-in-progress and exit all open applications. Shut down the operating system, computer and the Back-UPS.

Replace Battery (red) - is illuminated whenever the battery is near the end of its useful life, or if the battery is not connected (see above). A battery that is near the end of its useful life has insufficient run-time and should be replaced.

Chirps for 1 Minute Every 5 Hours - this alarm is sounded whenever the battery has failed the automatic diagnostic test.

TX/RX (green) - is illuminated whenever the Back-UPS is sending or receiving data over the network.

ACT/LNK (green) - is illuminated whenever the Back- UPS is connected to equipment and is ready and waiting to send or receive data.

Circuit Breaker - the circuit breaker button located on the bottom panel of the Back-UPS will stick out if an overload condition forces the Back-UPS to disconnect itself from AC utility power. If the button sticks out, disconnect non-essential equipment. Reset the circuit breaker by pushing the button inward.

In situations where the Back-UPS or connected equipment appears too sensitive to input voltage, it may be necessary to adjust the transfer voltage. This is a simple task requiring use of the front panel Power switch, or it can also be accomplished using the Configuration Page Screen (Figure 16) in the supplied software (see Install and Setup Software). To adjust the transfer voltage, proceed as follows:

1.Plug the Back-UPS into a the power source. The unit will be in a stand by mode (no indicators illuminated).

2.Press the front panel power switch fully inward for 10 seconds. All indicators on the Back-UPS will flash to acknowledge going into Programming Mode.

3.The Back-UPS will then indicate its current Sensitivity Setting, as shown in the following table.

Indicators	Sensitivity	Input Voltage	Use When
Flashing	Setting	Range (for
		utility
		operation)
1	Low	88 - 142 Vac	Input voltage is extremely low or high. Not
(yellow)			recommended for computer loads.
2	Medium	92 - 139 Vac	Back-UPS frequently goes On Battery
(yellow, and red)	(factory default)		(recommended).
3	High	96 - 136 Vac	Connected equipment is sensitive to voltage
(yellow, red, and red)			fluctuations.

4.To select the Low Sensitivity setting, press the Power switch until the yellow indicator is flashing.

5.To select the Medium Sensitivity setting, press the Power switch until the yellow and red indicators are flashing.

6.To select the High Sensitivity setting, press the Power switch until yellow and both red indicators are flashing.

7.To exit without changing the Sensitivity Setting, press the Power switch until the green indicator is flashing.

8.Once in Programming Mode, if the Power switch is not pressed within 5 seconds, the Back-UPS will exit Programming Mode; all indicators will extinguish.
