The distance from the unit lens to the screen determines to the size of the projected image, therefore, you need to consider the place where you set
up the unit and screen before making connections. You also need to consider the screen size and height of the unit and screen as other important factors.
Tip
A non-glossy wall may be used as a substitute for a screen.
WARNING
• Carrying the unit
Always carry the unit in the carrying case. Ensure that the power cable and any other cables connecting to video sources are disconnected
before moving the unit. When moving the unit or when it is not in use, cover the lens with the sliding lens cap.
• Only use the unit on a solid flat level surface. If the unit falls to the ground, you may be injured and the unit may severely be damaged.
• Do not use the unit where temperatures vary greatly. The unit must be used at temperatures between 5
°
C (41
°
F) and 35
°
C (95
°
F).
• Do not expose the unit to moisture, dust, or smoke. This will harm the screen image.
• Ensure that you have adequate ventilation around the unit to allow heat dissipation. Do not cover the vents on the bottom or the side of the unit.
Installation Guidelines (normal installation)
This section explains how to determine the screen size you use. Use the following table and charts as a guide.
Optimum focal point from the lens surface is as follows:
3.9 feet - 30.8 feet / 1.2 m - 9.4 m
Notes
• The range of error is +/- 5% because the distances are calculated values.
• Move the unit to the position where the projected image is horizontally centered to the screen.
• Do not use the unit where temperatures vary greatly. The unit must be used at temperatures
between 5˚C (41˚F) and 35˚C (95˚F).
• To raise the projection position, place the unit on the stable table.
• If strong light falls on the remote sensor, the remote control may not function. Do not place the
unit in direct lightning.
• For best results, do not expose the screen to direct sunlight or strong light.
