Channel Indicators The Channel Indicators will illuminate to display the channel that has been select- ed by the Channel Select Button. Channel Select Button The Channel Select Button allows you to change the transmit and receive fre- quency of the unit. Squelch On / Off Button The Squelch On / Off Button allows you to switch the squelch functionality either on or off.

Handle In Position 3 (Approximately 180°) To power the unit on, mate up the connector of the transducer cable to the Transducer / Power On / Off Port on the panel, rotate the cable connector gently until it indexes and lock into place with the cable’s locking ring. The unit’s LEDs will illuminate and a voice will read out the current settings.
Making Adjustments The following instructions will explain how and why to change your options and settings of the MilCom Surface Station. The table below lists the factory default options. The unit will remember Channel and Scrambler settings between uses, but will default to Speaker on and Squelch On when powered on. Option Default setting Channel...

Battery Charging The MilCom Surface Station is equipped with a high-capacity rechargeable Lithium-Ion battery that is charged through the Charger connector located along the bottom row of connectors. To charge the unit, connect the provided smart charging device. The LED on the Battery Charger will illuminate red, indicating that charging is in progress.
Maintenance Routine maintenance of the MilCom Surface Station 6000S units is necessary to ensure an extended life of the equipment. Failure to properly care for and maintain the MilCom Surface Station 6000S and ancillary components could lead to flooding of the units, damage to the connectors, transducers, housings and other failures.
Replacement Part Instructions NOTICE: For all replacement parts, do not use a power drill or power driver. Doing so will damage the unit. Do not tighten screws over 6 inch-pounds (0.6 newton-meters) Volume Knob 1. Firmly grab hold of the volume knob and pull it away from the panel. It will come loose with some force.

2. Remove the panel by lifting it from the panel handles. 3. Using a dull plastic tool, carefully remove the O-Ring located in the O-ring groove under the panel. 4. Replace the O-ring with the new undamaged part. 5. Place the panel back into the case and retighten the ten panel screws and nylon washers.
Page 21
Battery Bracket & Battery 1. Remove all ten panel screws and Nylon washers and set aside. 2. Lift the panel out of the case assembly and place it face-down on a clear work table. 3. Using a Philips head screw driver, remove the four screws that secure the battery bracket to the panel assembly.
Page 22
5. Disconnect the battery from the PCB and remove the battery from the battery bracket. 6. Place the battery into the replacement battery bracket. Place the battery brack- et onto the panel assembly, lining the bracket mounting holes with the mounting holes of the PCB.

3. Replace the Transducer by rotating the locking ring. The transducer will only go on one way. 4.Reassemble transducer cage and tighten the four screws Handle assembly 1. Remove the two visible screws using a Philips head screwdriver 2. Pull the handle open and rotate the handle down two steps as shown 3.
4. Pull the handle apart as you would to rotate it. The handle will now pull free from the unit. 5.Replace handle with new part by reversing these instructions.

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 The sound intensity from a source varies inversely with the distance from the...
Page 27
WATER TEMPERATURE Variations in water temperature affect 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 28
ZONES OF SILENCE Large natural or man-made objects can block acoustical transmission under cer- tain 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.
