• Manual . If you wish to manually adjust the power to suit current
conditions, you can adjust the power level between 0% and
100%, in 10% increments. Lower power levels are normally used
in depth ranges less than 8 ft. (2.4 m) and higher power levels are
typically selected for depths greater than 12 ft. (3.7 m).
