RMATION 2 1 22 DESCRIPTION VideoRay Explorer is a submersible Remotely Operated Vehicle ROV designed to take advantage of its portability and size Set up and vehicle control are simple and intuitive enabling VideoRay to be easily carried deployed and operated by one person VideoRay can go anywhere powered from AC or battery pack and inverter Operation of the VideoRay is quickly mastered after only a few practice flights Connection to a video monitor provides the operator with a view of everything the VideoRay sees VideoRay s pressure housings are machined from marine grade aluminum and protected by an anodized finish The vehicle is equipped with a forward camera two lights and three thrusters VideoRay carries no batteries it is completely powered and controlled from the surface through a small diameter tether The VideoRay power supply plugs into any standard grounded 100 240 Volts AC 50 60 Hz power source For operational safety the joystick control vehicle and tether carry a maximum voltage of 48 Volts DC OPERATING ENVIRONMENT VideoRay ROV Medium Fresh or Salt Water Operating Temperature 32 122 F 0 50 C VideoRay Power Supply Controller Caution While VideoRay is designed to be operated in water the Power Supply Controller is splash resistant and should not be subject to excessive water spray or rain when opened The Power Supply Controller case is watertight only when closed August
20. above it is always a good idea to consider where the tether lies as VideoRay moves through the water or along the bottom The following tips may assist in dealing with and or avoiding tether problems 1 Don t feed out unnecessary tether When flying VideoRay back along its tether haul in the slack line to avoid leaving a loop behind the vehicle 2 Avoid weaving in and around fixed objects like pilings rocks and anchors When operating in possibly fouled areas it is advisable to remain on the surface until VideoRay is approximately above your intended dive objective 7 4 FREEING A SNAGGED TETHER 1 Do not try to rip a snagged tether free In the event VideoRay s tether becomes snagged treat the situation as a challenge rather than a disaster Fly the VideoRay along the tether to determine the location of the snag If the problem area can be located visually using the vehicle appropriate corrective action can be taken 2 If the problem area cannot be located using VideoRay s camera try pulling gently on the tether Turn the vehicle power off and pull from different angles and directions if possible 3 In the event the tether cannot be otherwise freed it may be necessary to have a diver retrieve it manually In that event turn off the system power and unplug it from its power source 7 5 BALLAST SETUP VideoRay is configured at the factory to be neutrally buoyant in fresh water Depending upon the water conditions including sa
