Step 1
Make sure that the tether is connected correctly as this
will affect the buoyancy and trim of the LBV.
Step 2
Place the LBV in the same type of water in which it will
be operated, i.e. fresh, salt or brackish water. While
holding the handle or bumper frame, turn the LBV upside
down and agitate the LBV to release any trapped air.
Step 3
Place the lead weight strip found in the basic spares kit
(BSK) on the bumper frame to achieve the desired
buoyancy. You may have to cut the strips to fine adjust
the trim. Make sure that the LBV is level left to right and
fore to aft.
Step 4
Once the LBV is neutral, straighten the lead strips and
attach to the lower portion of the bumper frame using
M5x10 button head screws. Be sure to place in the
same relative position to ensure that the LBV is properly
set up left to right and fore to aft.

Calibrating
Compass
The LBV is fitted with a magnetic compass that is designed to provide basic heading
data. It should be noted that the sensor is fixed inside the LBV and therefore is
susceptible to varying environmental conditions. If the LBV is pitching up and down the
sensor will lose accuracy. Tilting the camera will also affect the heading display. To
ensure that the heading sensor provides the most accurate data, proper calibration is
critical.
Place the LBV either on a flat smooth stable surface or in still water. It is important that,
during calibration, the LBV does not pitch up or down. Access the calibration menu as
follows:
•

Press 5 (Main Menu)
•
Press 2 (Calibrate)

Press 4 (Compass)
