The threaded locking collar can be tightened to make a secure connection to the MilCom unit. TRANSDUCER ASSEMBLY The Transducer Assembly acts as the “antenna” of the unit. Transducers are replaceable.
- Page 12 RUBBER ARMORED BASE The Rubber Armored Battery Base protects the unit from impact and reduces abrasion damage as well as sliding on smooth surfaces. SEALING SCREWS The Sealing Screws are captive to the Rubber Armored Base. The Sealing Screws remain connected to the Rubber Armored Base even when fully disengaged from the Main Housing.

Page 13: Startup Guide
START-UP GUIDE Before diving, ensure the Lithium-Ion battery is fully charged. To charge the battery, remove the Earphone/Microphone (EM) cable by unscrewing the locking collar that retains the cable to the connector in a counter-clockwise direction on the top of the housing. With the collar free, grip the connector and pull straight up WITHOUT twisting to disconnect the cable. -
Page 14: Making Adjustments
MAKING ADJUSTMENTS The MilCom uses a voice menu system. This allows for adjustments of settings without the need for buttons or knobs penetrating the housing. Using a sequence of easily learned manipulations of the Push-To-Talk (PTT) button on the Earphone/Microphone Assembly allows you to control all of the features of the MilCom. -

Page 24: Understanding Wireless Underwater Communications
UNDERSTANDING WIRELESS UNDERWATER COMMUNICATIONS FACTORS THAT AFFECT WIRELESS COMMUNICATIONS There are many factors that affect the propagation of sound in water. The net result is that communication in water can be affected by local conditions and the kind and depth of dive being conducted. The following sections explain some of the factors that can affect the operating range of underwater communication: DISTANCE... - Page 25 WATER TEMPERATURE Variations in water temperature affects sound transmission most. In some areas of the ocean, the temperature changes at a fixed rate over large ranges of depth. If the temperature increases with depth, the velocity of sound increases and the sound waves will be refracted toward the surface.
- Page 26 ZONES OF SILENCE Large natural or man-made objects can block acoustical transmission under certain conditions, in much the same way that a rock blocks a fast-moving current of water. Close to the backside of the rock, in this example, the current is absent and the water seems still. A short distance away, the current is flowing again.
