To select the side in operation, hold the chestpiece stem in one
hand and rotate the chestpiece with the other hand until a click
is felt and heard. A light tap on the diaphragm or bell will help
determine which side is in operation as well.

Chestpiece Key

ADC®’s proprietary chestpiece design and slotted key allows
you to tighten the pediatric or adult assembly as securely as
you like (to reduce risk of loss) without fear of being unable to disassemble the rim in order
to replace a worn or broken diaphragm (a problem that often plagues less costly Sprague
scopes).

Replacing the Diaphragm

To replace a diaphragm, remove the desired
assembly by gripping the assembly firmly
and turning counterclockwise.

To loosen the diaphragm rim, insert the key
into the two slots located within the
threaded portion, located on the underside of the assembly. While holding the rim steady,
turn the key counterclockwise to loosen the rim. Remove worn diaphragm and replace with
new. Reassemble rim, and tighten by turning key clockwise until tight.

Then reassemble diaphragm rim back onto chestpiece drum by turning clockwise until tight.

Adjusting the Binaurals

To obtain the most comfortable acoustically sealed aural fit,
rotate each binaural tube approximately 15° forward, towards
the bridge of your nose. Simply twist each tube where it en­ters the tubing.

Adjusting the Spring Tension in the Binaurals

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 gradually until
desired tension is obtained. To increase the tension, grip the bin­aurals in the hand and squeeze the binaural tubes together gradu­ally. Caution: Excessive adjustment of the spring tension could
weaken the spring.
