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 3100 will be powered on when contact is detected on the
diaphragm or by button activation. Otherwise, the Model 3100 will completely power off after the period of time determined
by the POWER setting (see below).

10. Other Operating Considerations
Operating range is -22º to 104ºF (-30º to 40ºC), 15 to 93% relative humidity.
Storage and transport range is -40º to 131ºF (-40º to 55ºC), 15 to 93% relative humidity.
To extend the life of your stethoscope, avoid extreme heat, cold, solvents and oils. Remove the battery whenever the
stethoscope will not be used for several months.
If you plan to use the stethoscope below 0ºF (-18ºC) you should use a lithium battery to insure proper function.
Failure to follow care and maintenance recommendations could result in damage to the internal components of the Littmann
Electronic Stethoscope. Internal damage could cause malfunction of the product, ranging from a slight decrease in auditory
response to complete failure of the product.
If you experience any problems with the electronic stethoscope, do not attempt to repair it yourself. Please notify our 3M
Health Care Service Center for directions on shipping and receiving.
