power source, you could estimate that one 12V on-board could
mn
4-5 magazines and the VR42 for 4-5 hours.
In
order to con-
serve battery life, get into the habit
of
shutting off the assist when
not in use.
The VR46, on the other hand, because
of
its color, frame-store
and timecode capabilities, draws
730-750ma, which translates
into approximately 2 to 2.5 hours
of
operation from one 12V
l.8ah on-board battery. For this reason, it is recommended to
use a battery block or AC power supply when using the VR46
for long periods of time.
14.7lnstalling the CCD Heads
Under normal circurnstances,
if
you own a VR42 or VR46 CCD
assist, you will not need to deal with the removal and/or installa-
tion
of
the CCD head. The head and its accompanying relay lens
are designed to remain within the camera body whether the assist
is being used or not.
In sorne instances, however, such as the renting or sharing
of
a
unit among a few cameras, it would be necessary to remove
and install this head.
The installation and removal
of
the VR46 color head assembly is
somewhat involved and considered a shop operation. It is recom-
mended that this procedure
be
performed by a qualified techni-
ciano
The VR42, however, is much more sttaightforward; the
following is the procedure for its installation.
1 - Unscrew the four allen screws as indicated in the diagram on
page 41 and remove the
PBX coyer plate and mbber gasket. On
the cover plate, you'lI notice a plastic plug which is press-fit into
the coyer plate. Remove this plug by pushing it to the inside
of
the plate.
If
it is very tight, use a pencil eraser to
do
the job.
2 - Remove the four screws which hold the CCD cover onto the
battery side
of
the camera and carefully remove the CCD cover.
If
you do not own a VR42, you may have a fiat plate in place
of
the CCD coyer.
3 - Check that the exposed lens
of
the CCD head assembly is
free
of
dust particles.
If
necessary, clean this surface with
