The alarm will sound if the clamps are placed on the wrong poles of the battery. When the clamps are taken off the wrong battery poles the alarm will stop.
The alert will also sound if the unit detects excessive moisture. If the unit detects excessive moisture inside, the alarm will continue until the battery is completely run down. We suggest activating the work light to help run the battery down completely, once it has, make sure that the unit is in a dry place and allow it to sit for another 24 hours to make sure all components are dry before recharging unit.
