To select auto off power management: Select the AUTO OFF option in the SETUP menu. Use the (-) and (+) buttons to scroll
through the list of options. Press and release the (M) button to select. The factory default is ENABLE.
Two different settings work together to infl uence 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).
