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.

• Eartips can be removed from the eartubes for

thorough cleaning.

NOTE: Do not immerse your stethoscope in any liquid

or subject it to steam sterilization. If disinfection is

required, the stethoscope may be wiped with a 70%

isopropyl alcohol solution.
