Press and hold ON/Mute button for at least 2 seconds to turn on the UPS.
When the UPS is on battery mode, press and hold this button for at least 5 seconds to
When input frequency is within 40 Hz to 70 Hz, the UPS can
be set at a constant output frequency, 50 Hz or 60 Hz. The
UPS will still charge battery under this mode. Frequency

pressing this button.
Press this button to confirm selection in UPS setting mode.
Select Button
Press this button to change the LCD message for input voltage, input frequency, battery
