for gain control, VERT and HORIZ. These correspond respectively to surfacing, diving
and horizontal controls. The amount of power available can be anywhere from 10% to
the full 100%. Reducing the amount of available power to the thrusters gives the user
more control of the LBV.
NOTE
: When the LBV is powered up the default thruster gain is 50% showing
a 5 for V and H.

Trim
The trim function holds the thruster controls automatically. When the vertical thruster or
lateral thrusters are being operated, the trim key can be pressed to hold that input.
For example: If you are descending down to 50 meters, set the down thruster gain to
100%. Rotate the vertical thruster control knob to the dive position. Press the trim key
and center the vertical thruster control knob. The LBV will continue to dive until the trim
key is pressed again.

Auto
Functions
Auto Heading and depth are just as they sound. By pressing either of the keys, the LBV
will hold depth or maintain heading. A green LED above each key will illuminate to
show that the auto function is on. An important item to remember is that for this function
to operate correctly, the LBV must be on a stable heading and or at depth when the
function is selected.
Auto Depth
When a desired depth is obtained, press the Auto Depth key. The LBV will maintain the
depth as desired. Auto Depth is typically left on as the override is operating the vertical
thruster control knob. Usually the operator prefers that the LBV maintain depth making
piloting easier.
NOTE
: In order for Auto Depth to work properly, the LBV must be as close to
NEUTRALLY buoyant as possible.
Auto Heading
Enabling Auto Heading will make the LBV hold the compass heading displayed at the
time the Auto Heading key is pressed. Rotating the joystick will override the Auto
Heading. Pressing the Auto Heading key a second time will turn the function off.

Limitations

complicated or rough. Be aware of the following conditions:
