2-3. OPERATING PROCEDURE--Continued
Ear Cup Pad Rotation.
Bump on the ear cup pad should be in the depression
immediately below ear. This adjustment makes certain ears
fit into and are completely covered by, the ear cup pads.
This provides the most comfortable fit and seal.
(1) Adjust tension of ear cups for maximum sound attenuation by adjusting the crossweb straps. If
proper ear cup tension cannot be obtained by fully tightening the cross web straps, add spacers at the
back of the ear cups using the ear cup spacer kit. Use pressure sensitive adhesive to hold spacers in
position. For a proper and comfortable fit, make sure that the ear cup is correctly positioned with the
button of the ear cushion indexed to the depression just below the ear. To move the button to a new
position, rotate the ear cup assembly within the cloth retension system.
(2) Rotate ear cups pads (1 and 2) to position pad bump (3 and 4) for the most comfortable fit and seal.
Ear Cup Compression.
(1) Cross Straps (1 and 2).
(a) These straps control ear cup compression and are tightened or loosened as required.
