Packing/Unpacking
Inspect the shipping container for evidence of damage
immediately after receipt. If the shipping container or
cushioning material is damaged, it should be kept until
the contents of the shipment have been checked for
completeness and the units have been checked
mechanically and electrically.
The shipping container should be placed upright and
opened from the top. Remove the cushioning material
and lift out the contents.
The contents of the shipment should be checked
against the packing list. If the contents are incomplete,
if there is mechanical damage or defect, or if the units
do not perform correctly when unpacked, notify your
Thomson Multimedia Broadcast Solutions sales or
service centre within eight days. If the shipping
container shows signs of damage or stress, notify the
carrier as well.
If a unit is being returned to Thomson Multimedia
Broadcast Solutions for servicing, try to use the
containers and materials of the original packaging.
Attach a tag indicating the type of service required,
return address, model number, full serial number and
the return number which will be supplied by your
Thomson Multimedia Broadcast Solutions service
centre.
If the original packing can no longer be used, the
following general instructions should be used for
repacking with commercially available materials:
a. Wrap unit in heavy paper or plastic.
b. Use strong shipping container.
c. Use a layer of shock-absorbing material around all
sides of the unit to provide firm cushioning and
prevent movement inside container.
d. Seal shipping container securely.
e. Mark shipping container FRAGILE to ensure careful
handling.
Hardware Customization
The camera head is delivered in a ready-to-use state,
however, there are occasions when it might be
necessary to re-adjust some functions after, for
example, fitting a new lens.
A large number of functions can be set-up using the
control facilities of the menu system. In addition to this
software set-up there are some functions which can be
selected or adjusted internally in the camera.
Refer to the next chapters for instructions.
Lens matching
When a camera is supplied with a lens it is not
necessary to perform any of the following adjustments
as the lens is already matched to the camera. However,
if you wish to change to a different type of lens or the
lens is not supplied with your camera, back focus,
white shading and auto iris adjustment procedures
may have to be performed.
• Colour balance.
If required, perform the gain adjustment of the
preprocessor board and/or white shading adjustment
procedures, described in section 4.
• Auto Iris Adjustment
If a different lens either works too slow or overshoots
too much with the auto iris control, adjust the
potentiometer on the lens to obtain acceptable
operation. Refer to the lens documentation.
• Back Focus Adjustment
To adjust the back focus of the lens refer to the
documentation of the lens.
