Getting Started

Screen requirements

The ViewSonic PJ820 projects images onto flat screens. However, the brightness and viewable range varies with each type of screen. Selecting a screen with characteristics that are suitable for the intended use is important.

Screen Type

Polarized screen

White screen

Silver screen

FRONT Reflective Screens

Ceiling

Screen Characteristics

Because the surface of the screen has been treated to make it polarized, it will only reflect light from a single direction. Consequently, if you use such a screen with an LCD projector, a clear image can be obtained even in bright rooms because the screen hardly reflects any extraneous light.

This type of screen can be seen from anywhere, so there are no limits on the viewing position. However, the surrounding walls should be darkened as in a movie theater, otherwise a clear picture cannot be obtained.

This type of screen is recommended when the projector is suspended from the ceiling. This type of screen gives a picture 2-4 times brighter than a white screen. A variety of types are available from different manufacturers, and each type has different brightness characteristics. Some also have restrictions on the possible range of viewing positions.

Beaded screen

Maximum brightness

Flexible translucent screen

Rigid-type translucent screen

REAR Translucent

Screens

Maximum brightness

Reduced brightness

Care should be taken with screens that have a high gain, as these types of screen can cause color distortion at the left and right edges.

This type of screen is recommended when the projector is placed on the floor. This type of screen is similar to the silver screen, except that no color distortion occurs at the left and right edges. Moreover, most of the light is reflected at the same angle as the angle of incidence.

Floor

This type of screen is made of PVC (polyvinyl chloride). It has the same characteristics as silver screens, but sometimes has hot spots.

This type of screen is made of acrylic plastic. It is extremely durable and has excellent optical characteristics. It performs the same as silver screens.

Getting Started

ViewSonic PJ820

Standard setup positions

The illustrations and standard setup dimensions below help you determine where to set up the projector. Distance L from the projector to the screen and the height H do not vary, regardless whether the floor, table or ceiling are used to set up the projector, or whether a front or rear projection screen is used.

L: Projection distance H: Height from lower edge of projected image to center of lens

Standard setup dimensions

The further away the projector is from the screen, the bigger the picture is (image as shown in the table below). See also the table of screen requirements in this chapter with descriptions of various types of screens. These descriptions will help you determine whether to set up in front of or behind the screen and where to set up in the room. The projector uses a x 1.5 electronic zoom lens for adjusting the projection distance. You can also move the lens up or down. For instructions on adjusting the lens, the front of the projector, and focusing the image, see the Chapter 2 Operation. When the projector is not completely vertical with the screen and horizontal to the floor, the projected image distorts. The values in the table below are approximate.

Getting Started

System configuration

• Turn off the power supply of each system component before connecting any of the components.

• Read the instruction manual for each system component before connecting it.

• If there is a lot of jitter in the video signal input from the video source, the picture on the screen may

flicker. In such cases, it will be necessary to connect a TBC (time base corrector).

• The projector can be connected to video signal sources which output VIDEO, S-VIDEO and analog RGB

signals (0.6-8.0 Vp-p synchronized signals).

• The projector has built-in speakers. However, you will need to connect a separate audio system to the

AUDIO OUT terminal if your needs specify high sound volumes. No sound will come out of the projector’s built-in speaker while the AUDIO OUT terminal is being used.

Connecting to audio-visual equipment

In the above diagram, if the S-VIDEO IN and VIDEO IN connectors are both used at the same time, the SVIDEO IN signal input has priority. To view the signal being input to the VIDEO IN connector, disconnect the plug from the S-VIDEO IN connector.

Only one audio signal input is available for S-VIDEO or VIDEO signals. Select one or the other.

If the video signal source is connected using a cable with a BNC junction plug, use a BNC/RCA adapter to convert the pin jack.

If an audio system is connected to the AUDIO OUT connector, the sound volume balance and muting can be controlled by the Remote Control Unit which is supplied with the projector. However, if the volume is set to “0”, no audio signal will be output from the AUDIO OUT connector.

Changing the input source

You can select both the video and the corresponding audio signal input sources by pressing the INPUT button on the projector or the Remote Control Unit. The input source you select appears on the screen for approximately five seconds.

Projector Remote Control Unit

The video signal from the input signal source which is connected to the S-VIDEO/VIDEO IN connector appears.

The audio from the video source needs to be connected to the AUDIO IN (L-R) connectors for S-VIDEO/VIDEO input (page 8). However, only one audio input is available at one time. If you wish to change the audio input source, you will need to remove and insert the appropriate plugs.

The signal for RGB1 will be projected. The audio output will be the signal which is connected for RGB 1.

The signal for RGB 2 will be projected. The audio output will be the signal connected for RGB 2.

NOTE: The mode name for the currently-selected signal or the name of the signal format will be displayed directly underneath the on-screen display of the input signal source

The on-screen display of the selected input source normally appears when projection starts, and also when the input source is being switched. However, if the input display setting (INPUT DISP) has been turned off, this on-screen display will not appear.

If the S-VIDEO IN and VIDEO IN connectors are both connected, the S-VIDEO input will automatically be given priority. If you wish to view the signal being input to the VIDEO IN connector, disconnect the plug from the S-VIDEO IN connector.

If the picture is not projected normally when an RGB signal is being input, you will need to switch the signal mode to match the input signal.

If S-VIDEO or VIDEO has been selected as the input signal source, it may be necessary to select the correct format which corresponds to the input signal.

Troubleshooting

CARE AND SAFETY TIPS

CAUTION

●

If smoke, abnormal noise, or strange odor is present, immediately switch the projector off and call your dealer or ViewSonic Doing so in this condition could result in fire and/or electric shock.

●

Never unscrew and remove the top cover of the projector. However, to remove the small cover over the cable connections, see Chapter 1 on Getting Started. The projector contains high-voltage parts. You may receive an electric shock if you touch these parts.

For assistance call your dealer or ViewSonic® Customer Support.

Safety Precautions and Helpful Tips

Setting-up the projector

●

Place the projector in a well-ventilated area so heat from the projector will adequately dissipate.

●

Do not place anything on top of the projector.

●

Place the projector on a flat surface strong enough to support the projector's weight. Failing to do so could result in severe injury and/or damage to the projector.

®.

It is dangerous to continue using the projector.

●

Do not set up the projector directly on top of a plastic sheet or carpet. Plastic sheets can stick to the air filter, which can cause the inside of the projector to overheat and the power supply to switch off.

●

Do not cover the air filter or the air outlet, and do not put foreign objects into the projector. Doing so may cause the projector to overheat, which can cause fire, electric shock, and/ or damage to the projector.

●

Avoid setting up the projector in places which are subject to vibration or shocks. Strong motor vibration

will damage internal parts and may result in malfunctions or injury.

●

Avoid seting up the projector near high-voltage power lines or motors, which can cause electromagnetic interference.

●

If mounting the projector, ask a qualified technician do it. Improper installation can result in injury and/ or electric shock. To mount the projector on the ceiling, contact ViewSonic Ceiling Mounting Kit, Model No. CMK800.

Customer Support to order a

Power cord safety tips

●

Do not handle the power cord plug with wet hands. Doing so may cause electric shock.

●

Plug the power cord securely into the wall socket. Failing to do so may generate enough heat to cause a fire. If the plug is damaged or the wall socket plate is loose, do not use them.

●

Do not do anything that might damage the power cable, such as twisting or pulling it excessively, placing heavy objects on top of it, placing it near any source of heat, or by making modifications to it. If the power cable becomes damaged, have it repaired at an Authorized Service Center.

●

Be sure to unplug all cables before moving the projector.

●

When unplugging the power cable, hold the plug, not the cable.

ViewSonic PJ820

Care and Safety Tips

Using the projector safely

●

Do not look into the lens while the projector is being used. The strong light emitted from the projector’s lens can damage your eyes.

●

Do not put your hands, face or any objects close to the air outlet port. Doing so can result in burns and/or damage to objects.

●

Avoid exposing the projector to direct sunlight or other heat source.

●

Ensure the area around the projector is clean free of moisture, dust and oil fumes. Failing to do so can result in fire or electric shock.

●

Do not put objects on top of the projector. If an object gets inside the projector, call ViewSonic® Customer Support or an Authorized Service Center.

●

Do not remove the cover or modify it in any way. High voltages inside the projector can cause severe electric shock. For any inspection, adjustment or repair work, contact ViewSonic

Customer Support or an

Authorized Service Center.

●

Always handle the projector with care when moving it.

To get the best picture quality

●

Do not touch the surface of the lens with your bare hands. Dirt from fingerprints or anything else will be magnified and projected onto the screen.

●

When not using the projector, retract the lens and cover it with the lens cap. This prevents scratches on the lens which will lessen picture quality.

●

To ensure that the projected picture has good contrast, draw curtains or blinds over any windows, turn off any fluorescent lights near the screen, and cover floor or walls that have highly-reflective surfaces.

About condensation

●

Condensation is formation of water droplets on surfaces, such as on the cold windows that are warmed suddenly in winter. Condensation that occurs on the surfaces of lenses or the the mirror inside the projector may cause the picture to appear out of focus or may not be visible.

●

Excessive condensation causes the projector to stop functioning. Common causes of condensation are high humidity or the result of moving the projector suddenly from a cold environment into a warm one. In such cases, the projector normally resumes functioning as it becomes conditioned to the temperature of the new environment.

Care and Safety Tips

Cleaning and Maintenance

Be sure to unplug the power cord from the wall outlet before doing any cleaning or maintenance.

Cleaning the projector

●

To clean the projector housing, wipe it with a soft, dry cloth. If the housing is particularly dirty, wet the cloth in water mixed with a small amount of non-abrasive cleaner, squeeze the cloth thoroughly, and then wipe the projector housing. Then wipe the housing dry with a dry cloth.

●

To clean the lens use a photography lens blower/brush or a chamois cloth to wipe off any dust or lint.

Do not wipe the lenses with a cloth that produces lint or is covered with dust

●

Wipe the power cable regularly with a dry cloth to prevent it from becoming covered with dust.

Accumulated dust attracts humidity which could result in fire.

●

Ask an Authorized Service Center to clean inside the projector at least once a year. If dust is left to build up inside the projector without being cleaned out, fire or problems with operation can occur.

Cleaning the air filter

If the air filter becomes clogged, the internal temperature of the projector will rise. Then the TEMP indicator will flash and the projector will switch automatically to Standby Mode. If this occurs do the following:

1 Turn off the main power supply and unplug the power cord from the wall outlet. Turn off the main power

supply before unplugging the cord from the wall outlet. 2 Gently turn the projector upside down. 3 Remove the air filter cover. Hold the indents on the air filter cover with your hands and pull the air filter

unit out of the projector.
