Adjusting the Spring Tension in the Headset
To reduce the tension, grip the binaurals firmly
using both hands with fingers at the center of the
“Y” in the tubing,
thumbs at each side where
the tubing branches out. Flex bin
aurals gradu-
ally until the desired tension is obtained.
To increase the tension, grip the binaurals in the
hand and squeeze the binaural tubes together
gradually.
CAUTION: Excessive adjustment could weaken the spring.
Shortening the Tube Length (Clinician Models ONLY)
Clinician Series Adscopes are equipped with 22” tubing.
If a shorter length is desired, remove the chestpiece from
tubing. Cut tubing to desired length with a sharp single edge
razor on a hard surface. To soften tubing, use a hair dryer on
a low heat setting for approximately one minute, and reinsert
chestpiece stem in tubing.
CAUTION: Allow tubing to cool before using.
Replacing the Diaphragm
Select ADSCOPES
®
are equipped with up to two ultrasensitive, yet
extremely durable diaphragms. It is unlikely that they will ever
need replacement.
Snap-on (PVC) Rim: Snap off the rim and remove the worn di-
aphragm. Replace with new diaphragm and reattach rim by gently
stretching rim until the chestpiece edge inserts fully in the track
within the rim.
Threaded (Metal) Rim: Turn rim counterclockwise to remove.
Replace with new diaphragm and reattach rim by turning clock-
wise until tight to re-assemble.
