The ON DMND option will illuminate the backlight for five seconds by depressing and releasing the power button. The DISABLE option disables the backlight at all times and will conserve power.

Two different settings work together to influence the length of time the Model 3200 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.

When the AUTO OFF feature is enabled, the stethoscope will enter standby mode after a period of time determined by the POWER setting if there is no contact detected on the diaphragm AND the buttons are not activated. When the AUTO OFF feature is disabled, the stethoscope will enter standby mode after a period of time determined by the POWER setting from the last button activation. In addition, when the AUTO OFF feature is disabled, there will be an audible alert 10 seconds prior to entering standby mode. After entering standby mode, the Model 3200 will be powered on when contact is detected on the diaphragm or by button activation. Otherwise, the Model 3200 will completely power off after the period of time determined by the POWER setting (see below).
