8.3.11 How do I access the user adjustable controls?

CAUTION: DUE TO THE PRESENCE OF STATIC SENSITIVE COMPONENTS WITHIN THE
UNIT, ALL INTERNAL CAMERA OPERATIONS SHOULD BE PERFORMED ONLY BY
TRAINED TECHNICIANS AT AN ESD FREE WORKSTATION ! PLEASE CONSULT THE DVC
COMPANY BEFORE PROCEEDING; SOME INTERNAL OPERATIONS MAY VOID THE
WARRANTY !

NOTE: DISCONNECT THE CAMERA POWER BEFORE ATTEMPTING THE FOLLOWING
STEPS

In order to access the user adjustable controls within the camera:
Remove the camera cover:

8.3.11.1 Removal of Camera Cover:

Use a 1/16” hex socket driver for the following steps:

1) Remove the three #4-40 screws that hold the connector side panel to the back cover. Do NOT
remove the #4-40 screw that holds the connector side panel to the optical front plate.

2) Remove the #4-40 screw on the non-connector side panel that holds the non-connector side
panel to the optical front plate. Gently slide the back cover and the non-connector side panel off
as a single piece.

Note: The following steps are NOT required for normal access to camera adjustments.

8.3.11.2 Removal of Connector Side Panel:

1) Using a 3/16” nut driver, remove the two hex nuts that hold the DB-37 connector to the
connector side panel.

2) Using a suitable wrench, remove the hex nut and lock washer holding the BNC connector to
the panel.

3) Using a 1/16” hex socket driver, remove the #4-40 screw that holds the connector side panel
to the optical front plate.

4) The connector side panel can now be removed; it continues to be attached to the circuit
boards via the internal power supply cable.

Note: In order to access the video processor section, the optical front plate (attached to
the C-mount lens adapter) needs to be removed from the video board.

8.3.11.3 Removal of the Optical Front Plate:

1) Place the unit with the lens side down on a flat surface.

2) Using a 3/32” hex nut driver, remove the four black socket head cap screws that hold the
video board to the optical front plate. Note that after the screws are removed, the video board is
held to the optical front plate by the CCD sensor pins and the CCD sensor socket on the video
board.
