7. Monitor Patient Heart Rate
The Model 3100 detects and displays an acoustic-based heart rate when presented with consistent heart sounds (heart rate
variation < 10%). It takes five seconds to compute the initial heart rate and updates are provided every two seconds. Prior
to the initial reading, the display shows two dashes (--). For heart rates outside a range of 30-199 bpm, the display will also
show two dashes (--).
The acoustic-based heart rate display functions best when the Model 3100 is placed near the apex of the patient’s heart and
can be monitored while using any filter mode and/or volume level. If the heart rate changes from consistent to inconsistent or
if there is excessive ambient noise, patient movement or lung sounds during auscultation, the heart rate display number will
display two dashes (--).
8. Monitor Battery Life
Battery life is indicated by an icon in the LCD display.
The Model 3100 comes with a AA Alkaline battery.This battery will last for approximately 60 hours of continuous use. In a
typical clinical setting, this represents about three months.
As the alkaline battery life depletes, the icon will change as follows:
The battery icon begins to blink when only a few hours of battery capacity remains.
CAUTION: When the battery is completely depleted the scope becomes inoperable. No sound will be transmitted without
a functioning battery.

MAINTENANCE & WARRANTY
Cleaning
Cleaning of stethoscope should be done between each patient use.
Cleaning the Chestpiece
Under normal conditions, it is unnecessary to remove the diaphragm for cleaning. The diaphragm can easily be cleaned by
using an alcohol wipe. If however, it is necessary to remove the diaphragm, carefully follow the instructions below:
• Diaphragm Removal: With power off and diaphragm side up, using a thumbnail, lift the underside portion of the
diaphragm out of its designated groove, and peel it off of the chestpiece. The groove that holds the diaphragm in
place can be cleaned by sliding the edge of an alcohol swab around the groove. All parts of the chestpiece can be
wiped down with alcohol. IMPORTANT: The stethoscope should not be immersed in any solution. Excess liquid used
in the cleaning process may result in moisture getting into the internal components.
• Diaphragm Reassembly: Once the diaphragm is completely dry, insert the diaphragm into the groove of the rim,
starting at one point, and run your finger around the diaphragm until it is seated back in the groove.
Cleaning Other Parts of the Stethoscope
Eartips, eartubes, plastic tubing and chestpiece can be wiped clean with alcohol. Eartips may be removed for a more
thorough cleaning.
