Hot-plug precautions
• Although FireWire devices can theoretically be hot-
plugged without powering down equipment, we
strongly recommend turning the computer power off,
before connecting a digital camera to it via a FireWire
cable.
• Static electricity or slight plug misalignment during
insertion may short-circuit and damage components.
• The physical ports may be damaged by excessive ESD
(electrostatic discharge), when connected under pow-
ered 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.
Screw-lock precautions
• Also, all AVT 1394b camera and cables have industrial
screw-lock fasteners, to insure a tight electrical con-
nection that is resistant to vibration and gravity.
• We strongly recommend using only 1394b adapter
cards with screw-locks.
Caution
a
• Mount/dismount lenses and filters in a dust-free envi-
ronment, and do not use compressed air (which can
push dust into cameras and lenses).
• Use only optical quality tissue/cloth if you must clean
a lens or filter.
Ask your dealer if you are not familiar with these procedures.
