Subject:
New Microphone for Kirby Morgan Masks and Helmets

Products Affected:
KMDSI Masks, Helmets and all communications sets and assemblies.

KMDSI masks and helmets will soon ship with a new microphone. The microphone we used for many years is no longer available. We have found a new supplier who will build the microphones to Kirby Morgan’s specifications. The microphone will be of equal quality and durability.

KMDSI supplied microphones provide long life and high reliability. They work especially well in the damp and humid environments encountered in diving. These microphones outperform inferior cardboard speakers, which is essential in the demanding world of the commercial diver.

Parts that will be affected by this change include the following items:

• 515-009 Microphone

• 515-020 Microphone, SL27, EXO BR & Standard

• 515-029 Microphone Assembly (KM helmets)

• 315-017 Microphone Assembly, EXO Original

• and all communications sets and assemblies.
