For certain applications it may be recommended to take
out the filter by means of a special tool which can be
ordered from AVT under the following number:
E9020001.
Taking out the filter requires special care. Ask your
dealer to help you if you are not confident with the
procedure.

ALL CAMERAS
Do not touch the shield of the camera cable con-
nected to a computer and the ground terminal of the
lines at the same time.
Use only DC power supplies with insulated cases.
These are identified by having only two power connec-
tors.
Although IEEE 1394a and 1394b are functionally plug
and play, the physical ports may be damaged by exces-
sive ESD (electrostatic discharge), when connected
under powered conditions. It is good practice to ensure
proper grounding of computer case and camera case to
the same ground potential, before plugging the camera
cable into the port of the computer. This ensures that
no excessive difference of electrical potential exists
between computer and camera.
If you feel uncomfortable with the previous advice or if
you have no knowledge about the connectivity of an
installation, we strongly recommend powering down
all systems before connecting or disconnecting a
camera.
