The switches and indicator lights on the UPS front panel 

The following table describes the switches and indicator lights on the
front panel of the UPS.

1. AC Output          A green light--indicates that normal power
                      (AC) is being supplied to the receptacles
                      in the back.
2. Battery Power      A yellow light--indicates the unit is
                      supplying power during abnormal power (AC)
                      conditions.
3. Attention          A yellow light--indicates unit needs
                      attention.  This indicator light, in
                      conjunction with the audible alarm, can
                      have several meanings:

                      Light ON:

                         *   Charger fail:  the internal
                             batteries will not charge to
                             capacity.

                         *   Overload shutdown:  Excessive
                             overload causes the unit to
                             shutdown.

                         *   System fail:  the unit has failed
                             its calibration selftest.

                             A flashing light indicates an
                             overload condition.  With too much
                             equipment connected to the unit,
                             the light will flash
                             once-per-second and sound an
                             audible alarm.
4. Silence Alarm/Test A switch--if the unit is supplying power
                      during abnormal AC conditions, an audible
                      alarm sounds, pressing this switch
                      silences this alarm.  The TEST portion of
                      this switch can be used to switch the unit
                      from AC operation to battery operation
                      under controlled conditions.
5. Output On/Output   A switch--controls the output receptacles
   Off                in the back of the unit.

---------------------------------------------------------------------
| Audible alarm        | The audible alarm is located inside the    |
|                      | unit and is used in conjunction with the   |
|                      | Attention light and the Test switch.       |
|                      | There are three conditions that activate   |
|                      | the audible alarm:                         |
|                      |                                            |
|                      | 1.  Pushing the Test switch                |
|                      |                                            |
|                      | 2.  AC power fail and unit switches to     |
|                      | battery power.                             |
|                      |                                            |
|                      | 3.  Attention light comes on.  This could  |
|                      | be for an overload condition or a low      |
|                      | battery warning indicating two minutes     |
|                      | until battery depletion.                   |
|                      |                                            |
|                      | The beep sequence for the alarm is based   |
|                      | on a half (0.5) second interval timed at   |
|                      | 10 seconds per sequence.  For example, a   |
|                      | one beep alarm sounds for 0.5 seconds and  |
|                      | is off for 9.5 seconds, then repeats.  A   |
|                      | three beep alarm sounds three beeps (of    |
|                      | 0.5 seconds on, 0.5 seconds off) then off  |
|                      | for 7 seconds, then repeats.               |
