The rear panel of the Back-UPS consists of the

following elements:

Battery Back Up Outlets (qty. of 3). These

outlets provide battery back-up, surge protection,

and Electro-magnetic Interference (EMI) filtering.

In case of power outage, battery power is

automatically provided to these outlets. Power

(utility or battery) is not supplied to these outlets

when the Back-UPS is switched Off. Connect a

computer, monitor, and external disk or CD-ROM

drive to these outlets.

Surge Only Outlet. This outlet is always On

(when utility power is available) and is not

controlled by the On/Off switch. This outlet does

not provide power during a power outage. Connect

a printer, fax machine or scanner to this outlet.

Note: Allow the Back-UPS to charge for a full eight

hours prior to use.

Press the push-button on Back-UPS front panel.

Observe that the following events occur after pressing

and releasing the push-button:

• The green On-Line indicator flashes.

• The yellow On Battery indicator lights while the

Self-Test is being performed.

• When Self-Test has successfully completed, only

the green On Line indicator will be lit.

• If the internal battery is not connected, (see Step 1

above) the green On Line indicator and red

Replace Battery indicator will light. The Back-

UPS will also emit a chirping sound.

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

pushbutton. To adjust the transfer voltage, proceed as follows:

1. Plug the Back-UPS into the utility power source. The Back-UPS will be in a Standby Mode (no

indicators lit).

2. Press the front panel pushbutton 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.

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

5. To select the Medium Sensitivity setting, press the pushbutton until the yellow and red indicators

(second and third from the top) are flashing.

6. To select the High Sensitivity setting, press the pushbutton until yellow and both red indicators (bottom

three) are flashing.

7. To exit without changing the Sensitivity Setting, press the pushbutton until the green indicator is

flashing.

8. Once in Programming Mode, if the pushbutton is not pressed within 5 seconds, the Back-UPS will exit

Programming Mode; all indicators will extinguish.
