water. Dry all parts and surfaces thoroughly before
reassembly.
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.
This will facilitate assembly
and maintain smooth and quiet
low/high frequency alternation.
Snap the diaphragm with your
fingers to remove excess talc.
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. If necessary, flex the
assembly by pinching the outer
rim edge between the thumb
and fingers. Repeat this flexing
procedure after rotating the
assembly one quarter.
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 eartubes for
thorough cleaning.
NOTE: Do not immerse your stethoscope in any liquid
or subject it to steam sterilization. If
disinfection
is
required, the stethoscope
may be wiped with a 70%
isopropyl alcohol solution.
