4.11.2 To change the UPS O/P frequency at DC start

When the frequency value is blinking, push any selection button, △ or ▽, for 1 second to change

the frequency setting! The setting will keep changing every 2 seconds if you keep pushing the

button. Push two selection buttons at the same time for next setting, or leave the LCD blinking

without pushing any button for 30 seconds to end the setting.

4.11.3 To change the UPS rated voltage

When the voltage value is blinking, push any selection button for 1 second to change the rated

voltage. Keep pushing the button until the required voltage blinking. Then, push two selection

buttons at the same time for next setting, or leave the LCD blinking for 30 seconds to end the

setting.

4.11.4 To change the Auto-turn-on setting at the recovery of utility power

The method of changing the setting is similar to that of voltage setting. If you don’t need

Auto-turn-on function, please select “oFF”. To select “On” is for immediate auto turning on at the

recovery of utility power. While the “On.S” means auto turning on with safety mode. Sometimes,

when battery is empty after blackout, the auto turn-on function will have very short backup time if

blackout happened again following with a short time recovery. To select “On.S” will provide

Auto-turn-on only when the battery is charged for, at least, 30% of its capacity.
