Note: Only UPS models equipped with a “MUTE/TEST” switch allow you to “cold start” them and
use them as stand-alone power sources when utility power is not present. To “cold start” your UPS,
first turn your UPS ON. Then, move the MUTE/TEST switch to the left, hold momentarily and
release when the " " indicator light begins to flash.

Use this momentary switch to do two things:
Silence the UPS alarm*
Move this switch to the left and release it. Note: When the battery
is nearly depleted the alarm resumes (and cannot be silenced) to
alert you to immediately shut down connected equipment.

Test your UPS's battery charge
Leave your connected equipment ON. With your UPS plugged in
and turned ON, move this switch to the left; hold it there for 2
seconds and release it. The UPS will momentarily switch to battery
to test its charge. If the UPS alarm sounds or the properly-sized
load is not supported, let your UPS charge its batteries for 12 hours
and repeat the test. If alarm still sounds, contact Tripp Lite for
service. CAUTION: Do not unplug your UPS to test its batteries.
This will remove safe electrical grounding and may introduce a
damaging surge into your network connections.

*The UPS alarm consists of a series of short beeps followed by a brief pause. The alarm is activated
when the UPS switches to battery during a blackout or brownout.
when the UPS switches to battery during a blackout or brownout.
If you experience severe brownouts that cause the UPS to fre-
quently switch to battery, the adjustable voltage potentiometer
allows you to prevent excessive battery drain by lowering the
voltage point at which the UPS switches to battery. Turn it
clockwise to lower the voltage point as much as 18% below the
nominal setting of 99 volts (set fully clockwise).

Note: Your UPS’s optimal setting will depend on the voltage conditions in your area. Adjust it
clockwise until you reduce the frequency your UPS switches to battery. Your UPS will function
properly at any setting. Use caution when adjusting the potentiometer while the UPS is powering
voltage-sensitive loads.
