Maintenance

VistaPro 2000 User's Manual

4-1

VistaPro 2000 is CSA approved and is designed for safe and reliable operation.
However, safe operation cannot be assured by design alone; installers,
maintainers, and users must maintain a safe operating environment for the
system. Please read through and understand the following warnings and
guidelines promoting safe usage of the projector.

WARNING

Never look directly into the projector lens.

The high brightness of this projector

(2000 ANSI lumens) could cause

permanent eye damage.

WARNING

For protection from ultraviolet radiation,

keep all projector shielding intact during operation.

Observe and follow all warnings and instructions marked on
the projector.

The exclamation point within the equilateral triangle alerts the
user to important operating and maintenance (servicing)
instructions in the literature accompanying the projector.

The lightning flash and arrowhead symbol within the
equilateral triangle alerts the user to uninsulated "dangerous
voltage" within the projector's enclosure that may be of
sufficient magnitude to constitute a risk of electric shock.

Operate the projector in an environment which meets the operating range
specifications in Section 5, Specifications. Do not operate the projector close to
water, such as near a swimming pool.

Do not place the projector on an unstable cart, stand or table. If
the projector is to be ceiling mounted, only use an
Electrohome-approved ceiling mount fixture.

A projector and cart combination should be used with care.
Sudden stops, excessive force, and uneven surfaces may cause
the projector and cart combination to overturn.
