Congratulations on the purchase of your new
3M™Littmann

ClassicIII™Stethoscope.
The Littmann Classic III stethoscope provides high
acoustic sensitivity combined with exceptional
versatility. Its innovative design offers a tunable,
single-piece diaphragm on each side of the
chestpiece; the large side can be used for adult
patients, while the small side is especially useful for
pediatric assessment. Plus, the pediatric side of the
chestpiece can be converted to a traditional bell by
replacing the tunable diaphragm with the nonchill
bell sleeve included with your purchase. For more
information, visit www.littmann.com.

Instructions forUse
Place the Stethoscope in YourEars
The stethoscope headset is angled to complement
the anatomy of the typical ear canal and is designed
to provide a comfortable, acoustically sealed fit. The
eartips should point in a forward direction as you
insert them into yourears.
Adjust the Headset Tension
If necessary, you can adjust the tension in the
headset to ensure a tight, yet comfortable fit in
yourears.
To reduce the spring tension in
the headset, pull the eartubes
apart. Repeat until the desired
tension isachieved.
To increase the spring tension
in the headset, squeeze the
eartubes together. Repeat until
the desired tension isachieved.

Select the Active Side of theChestpiece
The Littmann ClassicIII stethoscope features
a two-sided chestpiece. Only one side of the
chestpiece is acoustically active at any one time,
which is identified by a mark on the stem. Rotate the
chestpiece to change which side isactive.
Littmann Tunable Diaphragm - Listen to Low and
High FrequencySounds
Both sides of the chestpiece are equipped with the
proprietary Littmann tunable diaphragm that enables
you to emphasize either low or high frequency
sounds by simply adjusting the pressure applied to
thepatient.
Low frequencies: To
emphasize lower frequency
sounds, use light pressure
against thepatient.
High frequencies: To
emphasize higher frequency
sounds, use firm pressure
against thepatient.
Convert to a Traditional OpenBell
The small side of the chestpiece
can be used with the Littmann
tunable diaphragm or it can be
converted to a traditional open
bell with the nonchill sleeve
included with yourpurchase.
To remove the Littmann tunable
diaphragm, pinch the rim of the
diaphragm with your thumb and
index fingernails; pull and lift the
diaphragm from thechestpiece.
To assemble the nonchill bell
sleeve, place one side of the
sleeve on the edge of the
chestpiece and stretch it over
and around the chestpieceedge.
To re-assemble the Littmann
tunable diaphragm, remove
the nonchill bell sleeve. Insert
the flexible edge of the tunable
diaphragm into the groove
of the rim and slowly roll
the rim around and over the
chestpieceedge.

Cleaning, Disinfection andStorage
Clean your stethoscope in-between each patient
with either a 70% isopropyl alcohol wipe or using
a disposable wipe with soap and water. It is a best
practice to use a disposable wipe when cleaning the
stethoscope to remove organicmaterial.
A 2% bleach solution may be used to disinfect your
stethoscope. However, stethoscopes that contain
red pigments in the tubing color (Burgundy, Pink,
Plum, Peach, Raspberry, Orange, etc) experience
slight discoloration after exposure to bleach. Due to
the destructive nature of bleach, only use a bleach
solution on a limited basis and/or whennecessary.
The tunable diaphragms, nonchill bell sleeve and
eartips may be removed for thorough cleaning
(ensure all parts and surfaces are dry before
reassembly). To remove the eartips from the headset,
pull firmly. To assemble the eartips, push the small
side of the eartip firmly onto the eartube until it
snaps fully intoplace.
Do not immerse your stethoscope in anyliquid.
Do not subject your stethoscope to any
sterilizationprocess.
Avoid storing your stethoscope in extremeheat.
