Battery Replacement

To insert or replace the battery,

use a coin to loosen the screw on

the underside on the neck of the

chestpiece and slide open the

battery compartment. Remove an

old battery by pushing through

the slot on the backside of the

battery compartment. Insert a

fresh battery with the positive end

toward the eartubes (the plus sign

will be visible in the battery

compartment after insertion).

Slide the compartment closed and

tighten the locking screw.

One battery is enclosed for use

with the Littmann Electronic

Stethoscope.

Use AAA alkaline batteries only

(IEC LR03, 1.5V). Carefully

follow all instructions and

warnings on the battery label and

package.

Remove the battery when the stethoscope will not be

used for several months.

General Use and Maintenance

Cleaning The Chestpiece

Under normal conditions, it is unnecessary to remove

the diaphragm for cleaning. The diaphragm can easily

be cleaned by using an alcohol wipe. If, however, it is

necessary to remove the diaphragm, carefully follow the

instructions below.

Diaphragm Removal

With diaphragm side up, using a thumbnail, lift the

underside portion of the diaphragm out of its designated

groove, and peel it off of the chestpiece. The groove that

holds the diaphragm in place can be cleaned by sliding

the edge of an alcohol swab around the groove. All parts

of the chestpiece can be wiped down with alcohol.

IMPORTANT: The stethoscope should not be immersed

in any solution. Excess liquid used in the cleaning

process can result in moisture getting into the internal

components.

Diaphragm Reassembly

Once the diaphragm is completely dry, insert the

diaphragm into the groove of the rim, starting at one

point, and run your finger around the diaphragm until it

is seated back in the groove.

Other Considerations

• To extend the life of your stethoscope, avoid extreme

heat, cold, solvents and oils.

• Eartips, eartubes, plastic tubing and chestpiece can be

wiped clean with alcohol.

• Do not immerse the stethoscope in any liquid or

subject it to any sterilization process.

• Eartips can be removed for a more thorough cleaning.

• Remove the battery whenever the stethoscope will not

be used for several months.

• Operating range 32˚ to 122˚F (0 to 50˚C), 15 to 95%

relative humidity.

Failure to follow care and maintenance

recommendations could result in damage to the internal

components of the Littmann Electronic Stethoscope.

Internal damage could cause malfunction of the product,

ranging from a slight decrease in auditory response to

complete failure of the product.

If you experience any problems with the electronic

stethoscope, do not attempt to repair it yourself. Please

notify our 3M Health Care Service Center for directions

on shipping and receiving.
