5.3 PRE-DIVE INSPECTION

A Pre-dive check should to be carried out prior to every dive.

1) Visually inspect the vehicle to ensure that the propellers are free of tangles and that the

vehicle is in operational condition. Check the propeller guards for damage and / or

misalignment.

2) Check the tether for scrapes, nicks or other visible damage.

3) Ensure that all fasteners are in place and secure.

4) Ensure that the VideoRay has been properly ballasted for the water conditions in which

you plan to dive, and that the ballast is secure. The VideoRay comes from the factory

ballasted for fresh water although water properties may vary locally and cause a need

for re-ballasting the VideoRay. See Section 7.5 for information on Ballast Setup.

5) Ensure that all cables are properly connected and the tether connectors are screwed

together to avoid separation and loss of the VideoRay ROV.

6) Power up the system by engaging the Main Power switch to the "On" position. The

monitor should automatically power up, but if it does not, there is a power button on the

monitor that may need to be pressed.

7) Using the joystick, displace it in all directions to test the port and starboard thrusters.

CAUTION! Do not operate the thrusters for more that 20 seconds when the VideoRay

ROV is out of the water. Prolonged operation in a dry environment will result in

damage to motor shaft seals.

8) Using the Depth Control knob, rotate it to test the vertical thruster. Return the knob to

the neutral position.

9) Verify that both lights are working by rotating the joystick toward "Bright", and then

returning the knob to the "Dim" position.

CAUTION! Do not operate the lights for more than 60 seconds when the VideoRay

ROV is out of the water. Doing so may cause overheating and damage the unit.

10) Test the camera tilt and focus functions. The Tilt and Focus switches are spring-loaded

momentary contact type switches and will return to the neutral position when pressure

is released. All switches, except the Main Power switch, work in this way.

11) Check the camera and monitor operation. If you are using a VCR, check that the

recording and playback functions are operational.

12) Power down the system until you are ready to launch the VideoRay.

CAUTION! Be certain that the tether connectors are securely connected and screwed

together to avoid separation and loss of the VideoRay ROV.

1) Power up the VideoRay.
