A three-position switch is located on the backup alarm. The three positions on the switch are HIGH position, LOW position and MEDIUM position. The three-position switch regulates the volume of the alarm.
The alarm is set from the factory at the highest sound level. The setting should remain on the HIGH position, unless the job site requires a lower sound level.
