Checking Battery Level

Battery level is indicated by LEDs on the 0-10 volume scale when the unit is manually turned off. As the LEDs scroll from left to right, the location on the volume scale where the lights stop scrolling indicates the charge that remains in the battery. For example, a stethoscope that is fully charged will scroll all the way to the 10 on the volume scale.

To manually shut off your stethoscope, simultaneously press and hold the "alt" and "minus" keys (the Quick Reference Guide provides a diagram labelling each button). The LEDs will then scroll from 0 to 10 on the volume scale and before the stethoscope shuts off.
