Operating considerations
Microphone
The microphone is supplied with a “flexible contacts protective band”. The band prevents interaction of the
mouth with the connectors.
The dynamic microphone is encapsulated and protected by a hydrophobic membrane. The microphone is
waterproof and is designed to handle operating under pressure. If the POD is removed underwater the micro-
phone WILL NOT suffer any damage. However, continuing to descend WITHOUT the POD sealed to the mask
of a distance greater than 33 fsw/10m may damage the microphone.
Ascending at a rate greater than 33 FSW/10m with an exposed microphone (POD not on the mask) can also
cause damage to the microphone. An ascent rate of 33 FSW/10m or slower will allow the expanding gas to
vent properly through the membrane, causing no damage to the microphone element.
Earphones
It is designed to work underwater so the best quality is achieved when the unit is submerged.
Post Dive
The communicator and microphone should be rinsed with fresh water (immersed, not a strong “flow of water”)
after each dive and should be placed in a well-ventilated area that is not exposed to direct sunlight to dry. D-
Mic does not have a polarity restriction when assembled on the PTT contacts. Be careful to unscrew the two
screws before removing it. Clean the contacts and lubricate them on a timely base.
