Transfer Voltage and Sensitivity Adjustment (optional)
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.
