Safety instructions
This chapter describes safety instructions/cautions valid for all AVT camera
families and special safety instructions/cautions depending on the camera
family/model used.
General safety instructions
Note
L
There are no switches or parts inside the camera that
require adjustment. The guarantee becomes void upon
opening the camera casing.
If the product is disassembled, reworked or repaired by
other than a recommended service person, AVT or its
suppliers will take no responsibility for the subsequent
performance or quality of the camera.
•The camera does not generate dangerous voltages inter-
nally. However, because the IEEE 1394a and 1394b
standard permit cable power distribution at voltages
higher than 24 V, please note that various country-
specific regulations apply.
Note
L
•All color models are equipped with an optical filter to
eliminate the influence of infrared light hitting the
sensor. Please be advised that, as a side effect, this fil-
ter reduces sensitivity in the visible spectrum. The opti-
cal filter is part of the back focus ring, which is
threaded into the C-Mount.
B/w models are delivered with a sensor protection
glass mounted in the back focus ring to ensure maxi-
mum sensitivity. In certain applications and depending
on the lighting source and optics, the use of either IR
blocking or IR passing filter may be required to improve
the image quality.
