Using the Projector Safely
Please read the following Safety Precautions before you start using the projector.
|
CAUTION: Possibly hazardous optical radiation is emitted from this product. As with any bright light source, do not stare into the beam, RG2 IEC 62471-5:2015
|
Glossary of Terms
Aspect Ratio
- Refers to the ratio of the image width to the image height.
- Maximizes the brightness of the projected image. This mode is ideal for environments where extra-high brightness is required, such as using the projector in well lit rooms.
Brightness
- Adjusts background black levels of the screen image.
- Synchronizes power on/off operation via HDMI connection. That is, if a device that also supports CEC function is connected to the HDMI input of the projector, when the projector’s power is turned off, the power of the connected device will also be turned off automatically. When the power of the connected device is turned on, the projector’s power will be turned on automatically.
Color
- Adjusts the color saturation.
Color Temperature
- Allows users to select specific color temperature settings to further customize their viewing experience.
Contrast
- Adjusts the difference between the image background (black level) and the foreground (white level).
- Manually improve the clarity of the projected image.
- Allows the user to manually select the greyscale curve of the projector.
- Audio/Video interface used to transmit video and audio via a single cable.
HDMI Range
- Allows the user to select HDMI greyscale range between 0~255 (full range) , 16~240 (limited range) or Auto by the signal type detected.
HDR (High-Dynamic Range)
- Keeps the brightness level and enhances details on the dark level.
High Altitude Mode
- Optional mode for users who live in an environment between 1,500 m and 3,000 m above sea level, and the temperature is between 5° C and 25° C. Activating it will improve projector cooling and performance.
- Displays the timing mode (video signal input), the projector model number, the serial number, and the ViewSonic® website URL.
Input Select
- Toggles between the various input options that are available for the projector.
- The distortion of an image caused by projecting it onto an angled surface.
- Use Normal or Eco mode to adjust the brightness level and power consumption.
- A Picture Mode appropriate for playing colorful movies, video clips from digital cameras, or DVs through the PC input. Best for a low light environment.
- Adjusts the picture quality of the monitor.
Troubleshooting Common Problems
Why doesn't the projector turn on?
Solution 1 ► Ensure the power cord is properly attached to the projector and to the power outlet.
Solution 2 ► If the cooling process has not completed, please wait until it has finished then try to turn on the projector again.
Solution 3 ► If the above does not work, try another power outlet or another electrical device with the same power outlet.
Solution 4 ► Check that the battery has remaining power, or needs external power.
Why is there no picture?
Solution 1 ► Ensure the video source cable is connected properly, and that the video source is turned on.
Solution 2 ► If the input source is not selected automatically, select the correct source with the Source key on either the projector or the remote control.
What should I do if the image is blurry?
Solution 1 ► Adjusting the Focus Ring will help correctly focus the projection lens.
Solution 2 ► Ensure the projector and screen are aligned properly. If necessary, adjust the height of the projector as well as the projection angle and direction.
Why is the remote control not working?
Solution 1 ► Ensure there are no obstacles between the remote control and projector; and that they are within 8 m (26 ft) of each other.
Solution 2 ► The batteries may be out of power, please check and replace if necessary.
What should I do if the projector freezes or doesn't respond?
Solution ► 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.
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.
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.
