8.15 Communications System

8.15.1 General

The communications system in Kirby Morgan hel-

mets requires regular attention and maintenance for

proper function. Clear two way speech communica-

tions between the diver and the surface crew is one

of the most important capabilities of surface sup-

plied diving operations.

8.15.2 Earphone Inspection

To service the earphones, first remove the head

cushion from the helmet. The earphones can be

carefully pulled out of the retainers in the helmet

shell for inspection and disassembly.
1) The rubber front cover is removed first, the rear

cover is next removed. The protector is now free.
2) Check the wire connections. They should be sol-

id.

3) Check the mylar diaphragm. If the mylar is torn

or loose, replace the entire unit, preferably with a

corrosion resistant, chrome plated mylar speaker

(Part # 515-008) Although cardboard speakers are

available at a lower cost than mylar speakers, they

are a poor investment.

The components of the communications system are shown here in exploded view.
