Maintenance

4.1 Warnings and Guidelines

The

Accurate

projection system is CSA

approved and is designed for safe and reliable

operation. However, safe operation cannot simply be assured by design; installers,
maintainers, and users must maintain a safe operating environment for the system. This
section covers warnings and guidelines, which promote the safe usage of the projector.
Please read through and understand these warnings and guidelines.

Labels and Markings>

Observe and follow all warnings and instructions marked on

the projector.

The exclamation point within the equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the projector.

The lightning flash with arrowhead symbol, within the equilateral triangle is intended to
alert the user to the presence of uninsulated ''dangerous voltage'' within the projector's
enclosure that may be of sufficient magnitude to constitute a risk of electric shock to
persons.

Projector Location

>

Operate the projector in an environment, which meets the operating range specifications
in Section 5. Do not operate the projector close to water - for example, 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 Accurate Imaging approved ceiling mount fixture.

The projector and cart combination should be used with care. Quick stops, excessive
force, and uneven surfaces may cause the

projector and cart combination to overturn.

Power Cord and Attachments>

Only use attachments or accessories recommended by Accurate. Use of others may result
in the risk of fire, shock or personal injury.

Do not allow anything to rest on the power cord. Locate the projector where the cord
cannot be abused by persons walking on it or objects rolling over it.
