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 horizon­tal 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.

(4.5 inch)

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 non­reflecting, 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
address, even when the displayed address is correct. Use the
numeric keys to enter the address.

Position of DIP switches and baud rate codes :

Baud Rate for communication with a
computer

The communication speed between the projector and the computer
has 8 possible settings. With DIP Switch No. 6, No.7 and No.8 of the
8 DIP switches on the controller board, labelled as ‘Baud rate code
(sum)’, it is possible to select the baud rate (communication speed).
Each DIP switch has its own decimal value. The sum of the values
associated to those DIP switches gives the baud rate code. Each
baud rate code corresponds an communication speed.

Password mode

With DIP Switch No.5 of the second set of 8 DIP switches on the
controller board, the projector adjustments can be protected with a
password. When the password feature is enabled, the user has to
enter a password before he can enter the adjustment mode (For more
information about password setting and reprogramming the pass­word, see Installation Adjustment).

When the password menus are disabled (adjust mode is unpro­tected), the adjust mode can be selected by pressing the <ADJUST>
key. This position of the DIP switch is useful for qualified service
technicians because they do not need a password to enter the adjust
mode.

Position of DIP Switch No.5 :

ON : password mode enabled.
OFF : password mode disabled.

Factory preset password mode : OFF.

Factory preset baud rate = 9600
