Instructions for Use
Changing Frequencies Using the
Tunable Diaphragm
Your Littmann Select Stethoscope is equipped with a
patented tunable diaphragm that enables you to listen to
both low and high frequency sounds without turning
over the chestpiece.
Low frequencies: To
listen to low frequency
sounds (traditional bell
mode) use very light skin
contact.
High frequencies: To
listen to higher frequency
sounds (traditional
diaphragm mode), press
firmly on the chestpiece.
To listen to low and high frequency sounds without
removing and repositioning the chestpiece simply
alternate between light and firm pressure on the
chestpiece.
Headset Adjustment
Your new Littmann stethoscope
is designed to provide a
comfortable, acoustically sealed
ear fit. Notice that the eartubes
are set to accommodate the
typical anatomy of the ear
canal. The eartips should point
in a forward direction as you
insert them into your ear canals.
To reduce spring tension in the
headset, hold each eartube at
the bend near the eartip and
gradually pull apart until fully
extended.
To increase spring tension,
grasp the headset with one
hand where the eartubes enter
the tubing and squeeze until the
tubing on one eartube touches
the other. Repeat as necessary.
This stethoscope utilizes a
unique design for attaching the
eartip to the eartube. The
eartips are pushed on to the end
of the eartube and snapped
firmly into place. To remove,
pull firmly on the eartip.

Removing the Diaphragm and
Cleaning the Chestpiece
With the diaphragm side up,
grasp the rim with the thumbs
and index fingers of both
hands and roll the rim off the
edge of the chestpiece.
Remove the diaphragm from
the rim and clean the parts in
soapy water or wipe with alcohol. Chestpiece surfaces
can be wiped with alcohol or soapy water. Dry all parts
and surfaces thoroughly before reassembly.
Assembly and Replacement of the
Tunable Diaphragm
Using your fingertip, apply a
small amount of talcum powder
to the inside surface of the
flexible edge of the diaphragm.
This will facilitate assembly
and maintain smooth and quiet
low/high frequency alternation. Snap the diaphragm
with your fingers to remove excess talc.
Insert the flexible edge of the
diaphragm into the groove of
the rim. This is best
accomplished by starting with
the rim positioned above the
legible side of the diaphragm.
Visually examine the ring to ensure that the flexible
edge is smoothly engaged inside the rim. If necessary,
flex the assembly by pinching the outer rim edge
between the thumb and fingers.
Repeat this flexing procedure
after rotating the assembly one
quarter.
To attach the rim/diaphragm
assembly to the chestpiece,
engage the groove of the rim
(with the diaphragm attached)
around the chestpiece at one
point and hold it in place with
your thumbs.
Slowly roll the rim around and
over the chestpiece edge using
both thumbs, moving in
opposite directions around the
chestpiece.
Visually inspect the edge where
the diaphragm engages the rim
for uniform containment.
Minor adjustments may be
made by slightly pulling and
rolling the rim away from the
diaphragm, allowing the diaphragm to slip into position.
General Use and Maintenance
• Avoid extreme heat, cold, solvents, and oils.
• The entire stethoscope can be wiped clean with
alcohol or soapy water.
