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 binaurals 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 (Non Cardiology Models
ONLY
)
All ADSCOPES
®
(except 600 Platinum Cardiology,601 Convertible Cardiology, 602 Cardiol-
ogy and 606 Cardiology-Lite models)
are equipped with 22” tubing for conven-
ience.
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 after heating
before handling.
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.
To replace the Snap-on (PVC) Rim
: Snap off the rim and re-
move the worn diaphragm. Replace with new diaphragm and reat-
tach rim by gently stretching rim until the chestpiece edge inserts
fully in the track within the rim.
