INDICATOR	DESCRIPTION
Online	This LED illuminates when the uninterruptible power supply is supplying utility power to
	the connected equipment. If not illuminated, the uninterruptible power supply is either not
	turned on, or is supplying battery power. When blinking, the uninterruptible power supply
	is running an internal self-test.
AVR Trim	This LED illuminates to indicate the uninterruptible power supply is compensating for a
	high utility voltage.
AVR Boost	This LED illuminates to indicate the uninterruptible power supply is compensating for a
	low utility voltage.
On Battery	This LED illuminates when the uninterruptible power supply is supplying battery power
	to the connected equipment.
Overload	This LED illuminates and the uninterruptible power supply emits a sustained alarm tone
	when the connected loads are drawing more than the uninterruptible power supply power
	rating (see Troubleshooting).
Replace Battery/	Failure of a battery self-test causes the uninterruptible power supply to emit short beeps
Battery Disconnected	for one minute and this LED to illuminate (see Troubleshooting).
	This LED also flashes and a short beep is emitted every two seconds to indicate when the
	battery is disconnected (see Troubleshooting).

FEATURE

FUNCTION

Power On	Press this button to turn on the uninterruptible power supply. (Read on for additional ca-
	pabilities.)
Power Off	Press this button to turn off the uninterruptible power supply.

Self-Test

Automatic: The uninterruptible power supply performs a self-test automatically when turned on, and every two weeks thereafter (by default). During the self-test, the uninter- ruptible power supply briefly operates the connected equipment on battery.

If the uninterruptible power supply fails the self-test, the replace battery LED illuminates and immediately returns to online operation. The connected equipment is not affected by a failed test. Allow the battery to recharge for 24 hours and perform another self-test. If it fails, the battery must be replaced.

Manual: Press and hold the button for a few seconds to initiate the self-test.
