Effective Range

To ensure proper function of the remote control follow the steps below:

  1. The remote control must be held at an angle within 30° perpendicular to the projector’s IR remote control sensor(s).
  2. The distance between the remote control and the sensor(s) should not exceed 8 m (26 ft.)

Replacing the Batteries

  1. To open the battery cover, turn the remote control over to view its back, open the cover in the direction of the arrow.
  2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative.
  3. Refit the cover by aligning it with the base and pushing it back down into position. Stop when it clicks into place.
NOTE:
  • Avoid leaving the remote control and batteries in excessive heat or a humid environment.
  • Replace only with the same or equivalent type recommended by the battery manufacturer.
  • If the battery is drained or if you will not be using the remote control for an extended period of time, remove the battery to avoid damage to the remote control.
  • Dispose of used batteries according to the manufacturer’s instructions and local environment regulations for your region.

Using the 3D Function

This portable cinema features a 3D function which enables you to enjoy 3D movies, videos, and sporting events in a more realistic way by presenting the depth of the images. You need to wear a pair of 3D glasses to view 3D images. If the 3D signal is input from an HDMI 1.4a compatible device, the portable cinema detects the signal for 3D Sync information and once detected, it projects images in 3D format automatically.

To activate 3D functions:

  1. When playing videos, press OK and the video control bar will pop up.
  2. Select the 3D settings icon, the 3D Settings menu is displayed in the right bottom corner.
  3. Highlight 3D self detect and change to Auto.
NOTE:
When the 3D Sync function is on:
  • The brightness level of the projected image will decrease.
  • The Color Mode cannot be adjusted.
  • If you discover the inversion of the 3D image depth, set the 3D Sync Invert function to ON to correct the problem.

Image Setting Menu

Menu Option Description
Aspect Ratio The Aspect Ratio is the ratio of the image width to the image height. With the advent of digital signal processing, digital display devices, like this projector, can dynamically stretch and scale the image output to a different aspect than that of the image input signal.


Auto
Scales an image proportionally to fit the projector’s native resolution in its horizontal width. This is suitable for the incoming image which is neither 4:3 nor 16:9 and you want to make the most use of the screen without altering the image’s aspect ratio.

4:3
Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 images like computer monitors, standard definition TV, and 4:3 aspect DVD movies, as it displays them without aspect alteration.

16:9
Scales an image so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for images which are already in a 16:9 aspect, like high definition TV.

Auto Keystone Provides a rectangular screen image by automatically adjusting the keystone number when there is a trapezoidal screen image caused by the tilting of the projector.
V Key Stone Keystone can be adjusted manually from -40 to 40.
Brightness The higher the value, the brighter the image. Lower values will result in a darker image.
Projector Brightness.png
Contrast Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment.
Projector Contrast.png

Display Mode Menu

Using the Projector Safely

Please read the following Safety Precautions before you start using the projector.

  • Keep this user guide in a safe place for later reference.
  • Read all warnings and follow all instructions.
  • Allow at least 20“ (50 cm) clearance around the projector to ensure proper ventilation.
  • Place the projector in a well-ventilated area. Do not place anything on the projector that prevents heat dissipation.
  • Do not place the projector on an uneven or unstable surface. The projector may fall over, causing personal injury or projector malfunction.
  • Do not use if the projector is tilted at an angle of more than 10° degrees left or right, nor at an angle of more than 15° degrees forwards or backwards.
  • Do not look straight at the projector lens during operation. The intense light beam may damage your eyes.
  • Always open the lens shutter or remove the lens cap when the projector lamp is on.
  • Do not block the projection lens with any objects when the projector is under operation as this could cause objects to become heated and deformed or even cause a fire.
  • The lamp becomes extremely hot during operation. Allow the projector to cool for approximately 45 minutes prior to removing the lamp assembly for replacement.
  • Do not use lamps beyond the rated lamp life. Excessive use of lamps beyond the rated life could cause them to break on rare occasions.
  • Never replace the lamp assembly or any electronic component unless the projector is unplugged.
  • Do not attempt to disassemble the projector. There are dangerous high voltages inside which may cause death if you should come into contact with live parts.
  • When moving the projector, be careful not to drop or bump the projector on anything.
  • Do not place any heavy objects on the projector or connection cables.
  • Do not stand the projector on end vertically. Doing so may cause the projector to fall over, causing personal injury or projector malfunction.
  • Avoid exposing the projector to direct sunlight or other sources of sustained heat. Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may increase the temperature of the projector to dangerous levels.
  • Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If the projector does become wet, disconnect it from the power supply and call your local service center to have the projector serviced.
  • When the projector is under operation, you may sense some heated air and odor from its ventilation grill. It is a normal operation and not a defect.
  • Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide and third blade are provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet.
  • When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.
  • Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the projector.
  • In some countries, the voltage is NOT stable. This projector is designed to operate safely within a voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10 volts occur. In areas where voltage may fluctuate or cut out, it is recommended that you connect your projector through a power stabilizer, surge protector, or uninterruptable power supply (UPS).
  • If smoke, an abnormal noise, or a strange odor is present, immediately switch the projector off and call your dealer or ViewSonic®. It is dangerous to continue using the projector.
  • Use only attachments/accessories specified by the manufacturer.
  • Disconnect the power cord from the AC outlet if the projector is not being used for a long period of time.
  • Refer all servicing to qualified service personnel.

Troubleshooting Common Problems

Problem or Issue Possible Solutions
The projector does not turn on
  • Ensure the power cord is properly attached to the projector and to the power outlet.
  • If the cooling process has not completed, please wait until it has finished then try to turn on the projector again.
  • If the above does not work, try another power outlet or another electrical device with the same power outlet.
  • Check that the battery has remaining power, or needs external power.
There is no picture
  • Ensure the video source cable is connected properly, and that the video source is turned on.
  • If the input source is not selected automatically, select the correct source with the Source key on either the projector or the remote control.
The image is blurry
  • Adjusting the Focus Ring will help correctly focus the projection lens.
  • Ensure the projector and screen are aligned properly. If necessary, adjust the height of the projector as well as the projection angle and direction.
The remote control does not work
  • Ensure there are no obstacles between the remote control and projector; and that they are within 8 m (26 ft) of each other.
  • The batteries may be out of power, please check and replace if necessary.
The projector/system is frozen and will not respond
  • Using a paper clip, carefully insert it into the Reset button at the rear of the projector to reset the device.

Maintaining the Projector

General Precautions

  • Make sure the projector is turned off and the power cable is unplugged from the power outlet.
  • Never remove any parts from the projector. Contact ViewSonic® or a reseller when any part of the projector needs replacing.
  • Never spray or pour any liquid directly onto the case.
  • Handle the projector with care, as a darker-colored projector, if scuffed, may show marks more clearly than a lighter-colored projector.

Cleaning the Lens

  • Use a canister of compressed air to remove dust.
  • If the lens is still not clean, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the surface.
CAUTION: Never rub the lens with abrasive materials.

Cleaning the Case

  • Use a soft, lint-free, dry cloth to remove dirt or dust.
  • If the case is still not clean, apply a small amount of non-ammonia, non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe the surface.
CAUTION: Never use wax, alcohol, benzene, thinner, or other chemical detergents.

Storing the Projector

If you intend to store the projector for an extended period of time:

  • Ensure the temperature and humidity of the storage area are within the recommend range.
  • Retract the adjuster foot completely.
  • Remove the batteries from the remote control.
  • Pack the projector in its original packaging or equivalent.

Disclaimer

  • ViewSonic® does not recommend the use of any ammonia or alcohol-based cleaners on the lens or case. Some chemical cleaners have been reported to damage the lens and/or case of the projector.
  • ViewSonic® will not be liable for damage resulting from use of any ammonia or alcohol-based cleaners.
