1SAFETY INSTRUCTIONS AND WARNINGS
NOTICEONSAFETY
Projectors are built in accordance with the requirements of the
international safety standards UL 1950 and CSA C22.2 No. 950,
which are the safety standards of information technology
equipment including electrical business equipment.
These safety standards impose important requirements on the
use of safety critical components, materials and isolation, in order
to protect the user or operator against the risk of electric shock
and energy hazard, and having access to live parts.
Safety standards also impose to the internal and external
temperature variations, radiation levels, mechanical stability and
strength, enclosure construction and protection against risk of
fire.
Simulated single fault condition testing ensures the safety of the
equipment to the user even when the equipment's normal
operation fails.
The lightning flash with an arrowhead within a
triangle is intended to tell the user that parts inside
this product risk electrical shock to persons.
The exclamation point within a triangle is intended
to tell the user that important operating and/or
servicing instructions are included in the technical
documentation for this equipment.
SAFETYWARNINGS
After re-assembly of the set, always m\perform an AC test on all
exposed metallic parts of the cabinet to be sure that set is safe to
operate without danger of electrical shock. DO NOT USE A LINE
ISOLATIONTRANSFORMERDURINGTHISTEST.UseanAC
voltmeter having 5000 ohms per volt or more sensitivity in the
following manner: Connect a 1500 ohm, 10 watt resistor,
paralleled by a 0.15 mfd 150V AC type capacitor between a
known good earth ground (water pipe, conduit, etc.) and the
exposed metallic parts, one at a time. Measure the AC voltage
across the combination of 1500 ohm resistor and 0.15 mfd
capacitor. Reverse the AC plug by using a non-polarized adaptor
and repeat AC voltage measurements for each exposed metallic
part. Voltage measured must not exceed 5.25 volts RMS. This
corresponds to 3.5 milliamp AC. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected
immediately.

thinner or benzine, or abrasive cleaners, since these will damage
the cabinet.
To ensure the highest optical performance and resolution, the
projection lenses are specially treated with an anti-reflective coating,
therefore : avoid touching the lens. To remove dust on the lens, use

On AC Power
1. This product should be operated from an AC power source
only.
This product is designed to operate from either a nominal
system voltage of 120V or 240V.
However, this product has been shipped from the factory
equipped with a standard three conductor North American
power supply cordset for connection to a 15 A, 125 V, 60 Hz
branch circuit receptacle outlet.
If you are not sure of the type of AC power available, consult
your dealer or local power company.
If the power supply is not the correct one, consult your dealer.
2.THISEQUIPMENTMUSTBEGROUNDED(EARTHED)viathe
supplied 3 conductor AC power cable. (If the supplied power
cable is not the correct one, consult your dealer.)
3. Do not allow anything to rest on the power cord. Do not locate
this product where people will walk on the cord. To disconnect
the cord, pull it out by the plug. Never pull the cord itself.
4. If an extension cord is used with this product, make sure that
the total of the ampere ratings on the products plugged into the
extension cord does not exceed the extension cord ampere
rating. Also make sure that the total of all products plugged into
the wall outlet does not exceed 15 amperes.
On installation
*Beforeoperatingyourprojector pleasereadthis manualthoroughly,
and retain it for future reference.
* Installation and preliminary adjustments should be performed by
qualifiedZENITHpersonnelorauthorizedZENITHservice dealers.
* Do not place this projector on an unstable cart, stand, or table. The
projector may fall, causing serious damage to it.
* Do not use this projector near water.
* Use only the power cord supplied with your projector. While
appearing to be similar, other power cords have not been safety
tested at the factory and may not be used to power the projector.
For a replacement power cord, contact your dealer.
* Slots and openings in the cabinet and the sides are provided for
ventilation; to ensure reliable operation of the projector and to
protect it from overheating, these openings must not be blocked or
covered. The openings should never be blocked by placing the
product on a bed, sofa, rug, or other similar surface. This product
shouldneverbeplaced near or overaradiatororheat register. This
projector should not be placed in a built-in installation or enclosure
unless proper ventilation is provided.
On Cleaning
Unplug this product from the wall outlet before cleaning. Do
not use liquid cleaners or aerosol cleaners. Use a damp cloth
for cleaning.

3INSTALLATIONGUIDELINES
Installationguidelines
Carefulconsiderationofthingssuchasimagesize,ambientlight
level, projector placement and type of screen to use are critical
to optimize the use of the projection system.
Environment
Do not install the projection system in a site near heat sources such
as radiators or air ducts, or in a place subject to direct sunlight,
excessive dust or humidity. Be aware that room heat rises to the
ceiling; Make sure the temperature near the installation site is not
excessive.
What about ambient light ?
The ambient light level of any room is made up of direct or indirect
sunlightand thelight fixturesintheroom.Theamountofambientlight
will determine how bright the image will appear. So, avoid direct light
on the screen as much as possible.
Windows that face the screen should be covered by opaque drapery
while the set is being viewed. It is desirable to install the projecting
systemina roomwhosewalls andfloorare ofnon-reflectingmaterial.
The use of recessed ceiling lights and a method of dimming those
lightsto anacceptable levelisalsoimportant.Toomuchambientlight
results in a ‘wash out’ of the projected image. This appears as less
contrast between the darkest and lightest parts of the image. With
biggerscreens, the‘wash out’becomes moreimportant. Asageneral
rule, darken the room to the point where there is just sufficient light to
read or write comfortably. Spot lighting is desirable for illuminating
small areas so that interference with the screen is minimal. What image size? How big should the image
be?
The projector is designed for projecting an image width from 1.4m
(4.6') to 6m (20') with an aspect ratio of 4 to 3. It leaves the factory,
adjusted as a ceiling/front projector for a screen width of 2.4m (7.8').
Changing the image size from the factory preset size requires a
realignment of the projector.
Which screen type?
There are two major categories of screens used for projection
equipment. Those used for front projected images and those for rear
projection applications.
Screens are rated by how much light they reflect (or transmit in case
of rear projection systems) given a determined amount of light
projectedtowardthem.The‘GAIN’ofascreenisthetermused. Front
and rear screens are both rated in terms of gain. The gain of screens
range from a white matte screen with a gain of 1 (x1) to a brushed
aluminizedscreenwithagain of 10 (x10) or more. Anotherimportant
consideration is the degree the screen's gain varies with the horizon-
tal and vertical viewing angle. The choice between higher and lower
gain screens is largely a matter of personal preference.
In considering the type of screen to choose, determine where the
viewers will be located and go for the highest gain screen possible.
A high gain screen will provide a brighter picture but reduce the
viewing angle.
For more information about screens, contact your local screen
supplier.
