Two different settings work together to inﬂ uence the length of time the Model 3100 is on full power: The AUTO OFF setting

(ENABLE vs. DISABLE) and the POWER setting (HIGH, MEDIUM, and LOW - HIGH setting uses more battery power, LOW setting

uses less battery power). To increase battery life, ENABLE the Auto Off feature and select the LOW power setting.
