Assembly and Replacement of the
Tunable Diaphragm (Pediatric side)
Remove the bell sleeve. Separate the stiff diaphragm
with flexible surround from the nonchill rim. Start by
placing the diaphragm on the pediatric side of the
chestpiece. Smooth the surface of the flexible part of
the diaphragm by rubbing your finger around the edge
of the diaphragm, making sure that the flexible portion
fits into the groove of the chestpiece. Engage the
groove of the rim around the chestpiece edge at one
point and hold it in place with your thumbs. Slowly roll
the rim around and over the chestpiece edge by using
both thumbs, moving in opposite directions around the
chestpiece.
Visually inspect the edge where the diaphragm engages
the rim for uniform containment. If necessary, remove
the rim, smooth the surface, and repeat application
procedure.
Conversion to Traditional Bell:
The pediatric side of the chestpiece can be converted to
a traditional bell. After removing the tunable
diaphragm, replace it with the nonchill bell sleeve
included in the spare parts box. Slip the bell sleeve
over the edge of the bell and fit it into place.
