Light & Motion VX2000 - Manual (Page 8)

Using Manual Focus
The Bluefin VX2000 FAR/-, NEAR/+ and MOM.AF buttons will switch the
camcorder from auto to manual focus.
One technique is to toggle the FAR and NEAR buttons until the subject is in
focus. Because this method is slow, we recommend the following technique.
1) While in auto focus, point the camera toward a solid object equidistant
to the actual subject you are trying to shoot (ie fin or boat bottom). This
allows the camcorder to achieve an actual focus.
2)
Press and release the MOM. AF button to lock the focus distance.
3) Re-orient the camcorder toward the actual subject.
4) Use the FAR and NEAR buttons to fine tune the focus.
5) Press REC / PHOTO when subject is in focus.
Replacing Handle Batteries
The battery life of your Smart Grip Handles will vary depending on usage
and technique. But eventually the handle batteries will exhaust.
Replacing the handle batteries is an easy procedure. However, pay special
attention to the wear of the O-ring and to the orientation of the batteries.
1) Using a hex key, remove the two hex screws on the back of the handle
(ref. fig. 13).
2) Remove the Handle Cap from the handle assembly (ref. fig. 13)
3) Remove old batteries from handle board.
4) Install new 1/3 N batteries into the handle board (Refer. fig. 14)
The +/- position of the batteries is critical. If batteries are
installed backwards, they will damage the handle board.
5) Service Handle Cap O-ring or replace with a new O-ring.
3) After frequent diving or if O-rings appear dirty, remove O-rings and clean
the grooves. To remove O-rings, use finger pressure or the rounded edge of
a plastic card to lift the O-ring out of the groove. The Rear Plate and Monitor
Back feature cutouts in the bottom corners to assist in O-ring removal.
Never use a metal object to remove an o-ring. It may cause
damage to the O-ring and mating surface.
4) To check O-rings for damage, place the o-ring between the index finger and
thumb. Then pull the O-ring through your fingers, feeling for any debris or
wear.
5) If O-rings are dirty, it is best to replace them. Washing dirty o-rings with soap
and water is not recommended. Soap breaks down the lubricants and will
compromise the integrity of the seal.
6) Properly greased O-rings will help maintain sealing integrity and minimize
O-ring degradation. Use enough grease to lubricate the O-ring thoroughly,
but not so much that it will attract additional debris.
7) Clean the groove with a lint free swab or the folded edge of a paper towel.
8) All of the front optic ports for the housing also utilize two O-ring seals. Also
check these seals every time the optic is removed.
O-ring Replacement Kit (part # 802-0163 )kit includes:
Two O-rings each for the Rear Plate and for front optic
Smart Grip O-ring and Battery Kit (part # 802-0117)
O-ring and battery set for one Smart Grip.
O-rings used for the Rear Plate, Monitor Back and all
optics are different sizes. Be sure to replace the appropriate
O-ring in its respective groove.
Focus Techniques
The camcorder’s auto focus works well for most video and Memory
Stick capture conditions. However, the properties of water can prevent
the camcorder from accurately judging distance. To overcome this, Light
& Motion has integrated manual focus ability into most housing
configurations.
Look for camcorder icons to appear in the view finder or
Monitor Back. This will identify when the camcorder is
operating in auto or manual mode. Refer to camcorder
manual for icon interpretation.
