ADSCOPE
®
combination stethoscopes you can se-
lect the use of either the diaphragm for monitoring high fre-
quency sounds, or the open bell for monitoring low frequency
response.
To select a side, hold the chestpiece valve stem in one hand
and rotate the chestpiece 180° with the other hand until it
“clicks” into place. The stem has an engraved dot, confirming
the activated side when it faces either the bell or diaphragm.
To confirm which side is activated, tap lightly on one side,
then the other, to hear which provides the positive response.
Converting the Chestpiece (601, 608 Only)
The 601 and 608 chestpiece drums accommodate 2 dif-
ferent chestpiece attachments of your choice. To attach
the bell you must first remove the pediatric diaphragm
and then thread the bell clockwise until tight.
To remove pediatric diaphragm, twist in a counterclock-
wise direction.
Orientation of the Headset
The binaurals (eartubes) are angled at 15° to per-
mit a comfortable, acoustically sealed aural fit.
Eartips should point forward, towards the bridge of
the nose to fit properly.
