Depth Control (Up | Hold | Down); Camera (Front | Rear) - VideoRay PRO 3 User Manual

VideoRay Pro 3 User's Manual
A unique and extremely valuable characteristic of the VideoRay is the "user selectable" mode of the third
axis control. The third axis mode can be set for any one of the following functions:
1) No Function – In this mode, the third axis does not perform any function. This is the default mode
when the VideoRay is powered on.
2) Depth Control Mode - rotating the joystick clockwise causes the VideoRay to dive, rotating
counterclockwise causes it to rise. The rate of depth change is proportional to the amount the knob
is rotated. In this mode, the joystick knob takes the place of the Depth Control knob, although the
Depth Control knob does not return to center with a spring the way the joystick does.
3) Camera Tilt Mode - rotating the knob counterclockwise tilts the camera up, clockwise tilts it down.
This takes the place of the Tilt switch, and is therefore not proportional. In other words, rotating the
joystick more will not cause the camera to tilt faster.
4) Lights Mode - rotating the knob counterclockwise decreases the brightness of the lights, rotating it
clockwise increases the brightness. The amount the knob is rotated determines the rate of change -
when centered the brightness level is held constant.
5) Manipulator Mode - rotating the knob counterclockwise opens the manipulator, rotating it clockwise
closes the manipulator.
Momentarily engage the Auxiliary switch to "On" to change the mode of the third axis. The mode cycles
from "No Function" through the four additional functions in the order they are listed above. The newly
selected third axis mode is briefly superimposed on the video display after switching functions.
Note: When the third axis mode is active, the corresponding control switch or knob for that function is
disabled.

DEPTH CONTROL (Up | Hold | Down)

A Depth Control knob on the left-hand side of the controller controls the vertical thruster. Rotating the
knob from the center detent position controls the rate of dive or ascent. Rotating the knob toward "Down"
increases the depth. Rotating the knob toward "Up" causes the VideoRay to move toward the surface.
VideoRay should be ballasted to always float upwards, so continuous downward thrust is necessary to dive
or to maintain a constant depth. When using Automatic Depth Control, the controller will maintain a
constant depth for you. Auto Depth Control is by default set to "Off" when the VideoRay Pro 3 is powered
up.
Automatic Depth Control (Auto-Depth)
When Auto-Depth is on and the Depth Control knob is centered on "Hold," the vertical thruster will
attempt to maintain a constant depth. Rotating the Depth Control knob away from the center position will
cause the VideoRay to rise or dive. Centering the knob again will then maintain the new depth. There may
be some "bounce" or overshoot after adjusting the depth when Auto-Depth is activated. Usually, waiting a
few seconds is all that is needed for the new depth to stabilize.
To activate or disable the Auto-Depth function, momentarily engage the Auxiliary switch to the "Off"
position. The newly selected on or off state of the Auto-Depth will be briefly superimposed on the video
display after toggling the Auxiliary switch. With Auto-Depth off, the Depth Control knob directly and
proportionally controls the amount of vertical thruster "up" or "down" power. When the knob is centered,
there will be no thrust and the VideoRay will rise or sink depending up on the ballast setting and the
presence of any vertical water currents.

CAMERA (Front | Rear)

This switch selects between the front and rear camera. Only one camera may be monitored at any time.
When selecting the camera, light control will automatically switch between the forward and rear lights as
appropriate.
