To reduce UPS sensitivity, press the voltage sensitivity button. Use a pointed object (such as a pen) to do so. Press the button once to set sensitivity to reduced. Press it again to set sensitivity to low. Press the button a third time to reset normal sensitivity. You also can change the sensitivity level through software.

Brightly lit: UPS is set to normal sensitivity.

Dimly lit:	UPS is set to reduced sensitivity.
Off:	UPS is set to low sensitivity.

The low battery warning beeps to indicate low on-battery run time. It beeps periodically (approximately three times per minute) when less than seven minutes of run time remain. The beeps are continuous when only two minutes of run time remain.

This may not be enough time to shut down some protected com- puter systems. To change the warning interval default setting, press the voltage sensitivity button while pressing and holding the

front-panel button.

Brightly lit: Low battery warning interval is about two minutes.

Dimly lit:	Low battery warning interval is about five minutes.
Off:	Low battery warning interval is about seven minutes.

This indicator illuminates when the UPS is connected to an im- properly wired AC power outlet.

If the UPS indicates a site wiring fault, get a qualified electrician to correct the building wiring.
