If the alarm sounds, this means that the input voltage is at or below 11 V. The bat- 1.
tery needs recharging. You should stop using the Power Inverter and recharge the
battery. If this is not done, the Inverter will shut off automatically at 10.5V.
If you are unsure if the inverter will have the proper amount of current to run your
