SAFETY INSTRUCTIONS AND WARNINGS

NOTICE ON SAFETY

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.

SAFETY WARNINGS

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

ISOLATION TRANSFORMER DURING THIS TEST. Use an AC

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.

INSTALLATION GUIDELINES

Installation guidelines

Careful consideration of things such as image size, ambient light

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

sunlight and the light fixtures in the room. The amount of ambient light

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

system in a room whose walls and floor are of non-reflecting material.

The use of recessed ceiling lights and a method of dimming those

lights to an acceptable level is also important. Too much ambient light

results in a ‘wash out’ of the projected image. This appears as less

contrast between the darkest and lightest parts of the image. With

bigger screens, the ‘wash out’ becomes more important. As a general

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

projected toward them. The ‘GAIN’ of a screen is the term used. 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

aluminized screen with a gain of 10 (x10) or more. Another important

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.

Where to install the projector ?

To indicate a correct installation position it is necessary to know :

• The distance from projector to ceiling in case of Ceiling

mounted or the distance from projector to floor in case of Table

mounted;

• The distance from projector to screen.

To find the correct position for the projector, use the following

formulas:

Abbreviations used in the calculations and the drawings :

• Install the projector water levelled in both directions

• Install the projector perpendicular to the screen

Top view

PD[inch] = 1.269 x SW[inch] + 7.12

A[inch] = 0.12 x SW[inch] - 9.70

In metric :

In inch :

PD[cm] = SW[cm] x 1.1358 + 18.53[cm]

A[cm] = SW[cm] x 0.142 - 25.26[cm]

B = Distance between ceiling and top of the screen (Ceiling

mounted) or distance between floor and bottom of the screen

(Table mounted).

A = Correction Value, extra value to be added to B to obtain the

correct installation position (In some cases the A value can be

negative).

CD = Total distance between projector and ceiling (Ceiling mounted)

or total distance between projector and floor (Table mounted).

CD = A + B.

Ceiling Mounted : when the result is negative, enlarge the

distance between ceiling and top of the screen, mount screen

lower, until CD becomes zero or positive.

Table Mounted : when the result is negative, enlarge the

distance between floor and bottom of the screen, mount

screen higher, until CD becomes zero or positive.

SW= Screen width.

PD = Perpendicular distance between screen and projector's mount.

To obtain the right values, you can make use of the new option

included in the Installation Adjustment Mode to let the projector

calculate the parameters automatically. Please refer to Chapter 8 for

details.

Mounting Configuration

Ceiling Mount

To install the ZENITH PRO 1200x in the Ceiling configuration, use

ZENITH'S Ceiling Mount Kit (PJR1200CE). Installation instructions

are included with this kit.

Table Mount

ZENITH offers a heavy-duty projection table with adjustable height

which allows the projector to be correctly positioned perfectly to the

installation requirements.

On illumination

In order to obtain the best quality for the projected image, it is essential

that the ambient light which is allowed to fall on the screen be kept

to an absolute minimum.

When installing the projector and screen, care must be taken to avoid

exposure to ambient light directly on the screen. Avoid adverse

illumination on the screen from direct sunlight or fluorescent lighting

fixtures.

The use of controlled ambient lighting, such as incandescent spot

light or a dimmer, is recommended for proper room illumination.

Where possible, care should also be taken to ensure that the floors

and walls of the room in which the projector is to be installed are non-

reflecting, dark surfaces. Brighter surfaces will tend to reflect and

diffuse the ambient light and hence reduce the contrast of the

projected image on the screen.

Setting the address is a hardware SETUP of your projector which

must be done during installation. Use the 8 DIP switches provided on

the controller board labelled 'Projector Address'.

Each DIP switch has its own decimal value. The sum of the values

associated to those DIP switches gives the address. As shown in the

table, if Switch No. 1 is set to ON, it represents a decimal value of 128,

Switch No.2 for 64, Switch No.3 for 32, and so forth.

In the given example, the projector address is set to 202 :

DIP switch No. : 1 2 3 4 5 6 7 8

Position ON/OFF : 1 1 0 0 1 0 1 0

Sum : 1x128 + 1x64 + 0x32 + 0x16 + 1x8 + 0x4 + 1x2 + 0x1 = 202

Factory preset address = 0

Note :

When the address button on the RCU is pressed, the projector will

display its own address on the screen. Once the address button is

pressed, to continue using your RCU, it is necessary to enter an
