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:

These are identified by having only two power connec-

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.
