To loosen the diaphragm rim, insert the key into the two slots on 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 it with a new one. Reassemble
the rim and tighten by turning key clockwise until tight. Then re-
assemble diaphragm rim back onto chestpiece drum by turning
clockwise until it is tight.
Orientation of the Headset
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 base of the binaural, thumbs at each side just
before the binaurals meet the tubing. Flex binaural spring
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.
