Smart - UPS AU750 ERROR cant use the system

Anonymous user · ‎2021-06-29

well I recently bought this item and when i hook it up to a battery and I press the power button/test it lights up and beeps a few times and then it stops and nothing happens. I plugged A small fan to the back to see if it could power the fan but nothing happened.
