Inserting the ballast
Proceed as follows to insert the ballast (23): (see fig. 9)
Open the HDV and extract the battery (see previous chapters).
Insert the ballast in the specific housing being careful to screw in the two yellow ballast
stop knobs (21) without forcing them.
IMPORTANT NOTE: Figure 9 illustrates the HDV in salt water settings, when using
the HDV in fresh water, the ballast (23) should be removed from the HDV, the two
knobs (21) may stay screwed into the HDV. This makes the HDV lighter and re-
establishes the correct centre of gravity for the HDV to assume the right position
underwater.

Settings and trim adjustments
You may need to adjust the float or trim settings (trim is the HDV longitudinal axis
inclination).
As for floating, the HDV is produced to slightly float in both fresh water (without using the
ballast 23) and salt water (using the ballast 23).
As for trim, you can change factory settings by moving the battery along the rods (13) fig.3.
Remove the battery, rotate the screw (21) with a 5 mm Allen key, screwing in or out to
adjust the battery position. Screwing it in, the HDV tends to position itself with the rear
sinking, unscrewing it causes the opposite. Replace the battery connect the terminal (12)
and the ring nut (11) try the HDV in the water until the desired settings are reached (see
fig. 10).
