Instructions for Use:

The stethoscope is controlled by a single button on the

top of the chestpiece and has four activation points

identified as follows:

Button symbol Function

Bell filter button

Single Tone

Diaphragm filter button

Double Tone

Increase volume button (Single tone

representing volume increase each

time button depressed)

Decrease volume button (Single tone

representing volume decrease each

time button depressed)

Turning on the Stethoscope

The device may be activated by pushing one of the

two filter-mode button

(The specific identifying filter tone will be

heard upon activation)

Operation

Select the frequency mode desired for auscultation by

pushing either the bell or diaphragm filter symbol (this

is accomplished when activating the stethoscope

initially). Adjust the volume to the desired level by

pushing either the plus or minus symbol. At the 4th

volume level, the stethoscope is set to the approximate

gain of a typical acoustic stethoscope.

You can change the preset volume level by holding

down the volume button at the desired volume until you

hear a double tone signal. The stethoscope will start at

that volume level each time the scope is turned on until

you program it differently. Changing the volume during

auscultation will not affect the preset volume setting

you have established.

Auscultate as you would using an acoustic stethoscope.

It is important to find a comfortable grip that allows you

to hold the stethoscope in a secure but relaxed manner.

Use the bell and diaphragm modes to accentuate or

attenuate different heart and body sounds. Low

frequency sounds have a tendency to mask or obscure

the high frequency sounds. Adjust volume control as

necessary.

Headset Positioning

Your new Littmann Electronic

Stethoscope is designed to give

you a very comfortable,

acoustically sealed ear fit. Notice

that the eartubes are permanently

set at an angle to accommodate

Correct

the typical anatomy of the ear

canal. The eartips should point in

a forward direction as you insert

them into your ear canals.

Incorrect

To reduce spring tension in the

headset, hold each eartube at the

bend near the eartip and gradually

pull apart until fully extended (180

degrees).

Reduce Tension

To increase spring tension, grasp

the headset with one hand where

the eartubes enter the plastic

tubing and squeeze until the

plastic tubing on one eartube

touches the other. Repeat as

necessary.

Increase Tension

For maximum acoustic performance, comfortable

patented Littmann Soft-Sealing Eartips are provided

with your stethoscope.

The 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 tight. To

remove, pull firmly on the eartip.

Additional Littmann eartips are available. To order,

contact your Littmann Stethoscope distributor or the 3M

Health Care Service Center.

Turning Off the Stethoscope

The stethoscope will automatically turn itself off after 3

minutes of no button activation. You can also turn the

scope off manually by depressing either filter mode

button and holding it down until you hear a diminishing

triple tone.

Battery Life

The battery will last for approximately 200 hours of

continuous use. In a typical clinical setting, this

represents about six months. When the Low Battery

Indicator Tone is heard, sufficient battery power remains

for approximately 2 hours of normal auscultation

activities. When the battery is completely depleted the

scope becomes inoperable. It is important to remember

that there is no acoustic (non-amplified) mode available

in the Littmann Electronic Stethoscope. When the

battery is finally exhausted, the stethoscope will not

operate.
