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.

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

Correct

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.

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

Incorrect

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.
