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.

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.

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

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 = Totaldistancebetweenprojectorandceiling(Ceilingmounted)
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 = Perpendiculardistancebetweenscreenandprojector'smount.
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.

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
enterapasswordbeforehecanentertheadjustmentmode(Formore
information about password setting and reprogramming the pass-
word, see Installation Adjustment).
When the password menus are disabled (adjust mode is unpro-
tected), 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
More information about computer communication with the ZENITH
PRO 1200X is available in the Projector Control Software manual.
