During normal operation, the first line of your LCD Display shows which operating mode your UPS is in: Online, Economy, On Battery,
or Bypass.
Online mode: The UPS provides AC power while utility power is available and switches to On Battery mode instantly (zero transfer time)
if AC power is interrupted.
Economy mode: The UPS provides AC power at high efficiency while utility power is available and switches to On Battery mode quickly
if AC power is interrupted.
On Battery mode: The UPS provides AC power from battery backup so long as battery power lasts. It switches back to Online or Economy
mode if utility power is available and shuts down if it runs out of battery power.
Bypass mode: The UPS provides AC power while utility power is available. The UPS shuts down if AC power is interrupted.
The second line of the LCD Display shows basic power conditions. Push the SCROLL buttons to browse through these basic power conditions

will beep twice a second. If its connected batteries are nearly depleted, the UPS power module will beep continuously.
To silence the On Battery Alarm, press the “ON/MUTE” button.
When the UPS detects an output overload, its LCD will switch to the following display:
The UPS will then begin a countdown. If the UPS is still overloaded at the end of the countdown, the UPS will automatically go to Bypass
