A/B requires regular attention and maintenance for
proper function. Clear two-way speech communica-
tions between the diver and surface crew is one of
the most important capabilities of surface-supplied
diving operations.
8.9.2 Earphone Inspection
To service the earphones, first remove the head cush-
ion from the helmet. The earphones can be carefully
pulled out of the retainers in the helmet shell for
inspection and disassembly.
1) Remove the (clear) cover first and slide it along the
wire to get it out of the way. Remove the earphone
protector and then peel back the (black) rear cover.
2) Check the wire connections. They should be solid.
3) Check the mylar diaphragm. If the mylar is torn
or loose, replace the entire unit, see "8.9.4 Earphone
Removal and Replacement" on page 135.
4) If the rubber covers are worn or damaged, replace
them also.
To gain access to the earphones, you must first remove
the head cushion.
Remove the earphones from the retainers to inspect
the speaker cones.
Check the earphones regularly, especially if water
has entered your helmet.
