snapped firmly into place. To remove, pull
firmly on the eartip.
Removing the Diaphragm and
Cleaning the Chestpiece:
With the diaphragm side
up, push the rim at the
apex with both thumbs
and roll the rim off the
edge of the chestpiece.
Remove the diaphragm
from the rim and clean
parts in soapy water or
wipe with alcohol. Wipe chestpiece surfaces
with alcohol or soapy water. Dry all parts and
surfaces thoroughly before reassembling.
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 then align the
rim and diaphragm as a
unit. This will facilitate
assembly and maintain
smooth and quiet
low/high frequency
alternation. Snap the
diaphragm with your
fingers to remove excess
talcum powder. 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.
Refer to illustration for
correct assembly of the
non-chill rim and
diaphragm. If necessary,
flex the assembly by
pinching the outer rim
edge between the thumb
and fingers. 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 ear-tubes
for thorough cleaning.
