USB COMMUNICATIONS PORT
The USB communications protocol is HID.  The HID USB driver comes stan-
dard in the Windows OS.  Simply plug the USB cable into the UPS and the
computer then follow the prompts on the screen.

WEAK/BAD BATTERY
The UPS automatically tests the battery’s condition and will illuminate the Bad
Battery/Overload/Fault LED and sound the alarm.  This alarm will be repeated
until the batteries pass a self test.  If the battery is weak, bad or disconnected,
the Bad Battery/Overload/Fault LED will illuminate and the alarm will beep three
times every thirty seconds until the battery is reconnected or replaced.  It is
recommended that the UPS be allowed to charge overnight before performing a
battery test to confirm a Weak/Bad Battery condition.

OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
Bad Battery/Overload/Fault LED will illuminate and the UPS will sound 1 beep
every half second (AC and Battery modes).  This alarm will remain on until the
excess load is removed or the UPS’s self protection circuit shuts the UPS
down.

POWER MONITORING SOFTWARE
The UPS comes with power monitoring software.  See the software CD for the
installation of the power monitoring software.

ALARMS

ON BATTERY
When the UPS is operating on the batteries, the On Battery LED will illuminate
and the audible alarm will sound once every five seconds.  The alarm will stop
once the UPS returns to the AC normal mode.

LOW BATTERY WARNING
The UPS will sound two beeps every five seconds when the battery reserve runs
low.  This condition will continue until AC returns or the UPS shuts down from
battery exhaustion.

UPS FAULT
When the UPS detects a hardware fault, the Bad Battery/Overload/Fault LED
will illuminate and the UPS will sound a constant alarm.  The fault condition, in
some instances, may be reset by turning the UPS off and then on.

TURNING THE UNIT ON/OFF

On / Off Button
Press and release the On/Off Button to turn the UPS on.  The alarm will sound
one beep and the LEDs will cycle while the UPS performs a five second internal
self-test.  Once the UPS has passed its internal self-test the UPS will provide
an output and the load will be powered.  Press and release  the On/Off Button
to turn the UPS off.  The UPS will continue to charge the batteries whenever it
is plugged into a wall outlet and there is an acceptable AC voltage present.
