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.
