Safety precautions
Mounting to a firm place
As the unit rotates at high speed, mount it on a
firm place with sufficient strength to support
the vibration and weight of the unit
Mass:Approx. 1.9 k g (VN-V685U/VN-V686BU)
:Approx. 5.5 k g (VN-V686WPBU)
If the strength is weak, the vibration will cause
fuzzy images on the monitor screen. In the
worst scenario, the camera may even fall off
and hit somebody, resulting in serious
accidents.
Mounting the camera correctly with
the designated clamping brackets
Always use the designated clamping brackets.
Be sure to connect the fall prevention wire and
tighten the fixing screws or nuts securely.

Hz/60 Hz. Supplying a power beyond the rated
value may result in failures and in the worst
scenario, smoking and fire.
This unit is able to divert lightning conduction
to itself and the connecting cables to a certain
extent but this is not 100 % guaranteed. For
installation locations that are likely to suffer
lightning strikes, be sure to take appropriate
measures such as adding arrestor to the
connecting cables.
Consult your dealer as special technique is
