contact to have the projector repaired.
9. Do not look straight into the projector lens during operation. It may harm your sight.
10. Do not operate the projector lamp beyond the rated lamp life. Excessive operation of lamps
beyond the rated life could cause a lamp to break on rare occasions.
11. The lamp becomes extremely hot during operation. Allow the projector to cool for approximately 45
minutes prior to removing the lamp assembly for replacement.
12. Never attempt to replace the lamp assembly until the projector has cooled down and is unplugged
from the power supply.
13. This projector is capable of displaying inverted images for ceiling mount installation. Use only a
proper ceiling mount kit for mounting.
14. THIS APPARATUS MUST BE EARTHED.
15. When installing the unit, incorporate a readily accessible disconnect device in the fixed wiring, or
connect the power plug to an easily accessible socket-outlet near the unit. If a fault should occur
during operation of the unit, operate the disconnect device to switch the power supply off, or
disconnect the power plug.
High temperature Caution
The temperature of the cabinet around and above the exhaust vents can become hot during
projector operation. Touching these areas during operation could cause burns to the hands. Do
not touch these areas. Doing so may cause burns. Pay particular attention in preventing young
children from touching these parts. Additionally, do not place any metal objects on these areas.
Due to the heat from the projector, doing so could cause an accident or personal injury.
Ceiling mounting the projector
If you intend to mount your projector on the ceiling, we strongly recommend that you use a
proper fitting projector ceiling mount kit and ensure it is securely and safely installed.
If not, there is a safety risk that the projector may fall from the ceiling due to an improper
attachment through the use of the wrong gauge or length screws.
You can purchase a proper projector ceiling mount kit from the place you purchased your
projector. We recommend that you also purchase a separate Kensington lock compatible
security cable and attach it securely to both the Kensington lock slot on the projector and the
base of the ceiling mount bracket. This will perform the secondary role of restraining the
projector should its attachment to the mounting bracket become loose.
Do not attempt to disassemble this projector. There are dangerous high voltages inside which
may cause death if you should come into contact with live parts. The only user serviceable part is
the lamp. See page 33.
Under no circumstances should you ever undo or remove any other covers. Refer servicing only to
suitably qualified professional service personnel.
Please keep the original packing for possible future shipment. If you need to pack your projector
after use, adjust the projection lens to an appropriate position, put the lens cushion around the
lens, and fit the lens cushion and projector cushion together to prevent damage during
transportation.
RG2 IEC 62471-5:2015

6 Important safety instructions
When you think service or repair is required, take the projector only to a suitably qualified
technician.
Moisture condensation
Never operate the projector immediately after moving it from a cold location to a hot location.
When the projector is exposed to such a change in temperature, moisture may condense on the
crucial internal parts. To prevent the projector from possible damage, do not use the projector for
at least 2 hours when there is a sudden change in temperature.
Avoid volatile liquids
Do not use volatile liquids, such as insecticide or certain types of cleaner, near the projector. Do
not have rubber or plastic products touching the projector for a long time. They will leave marks
on the finish. If cleaning with a chemically treated cloth, be sure to follow the cleaning product’s
safety instructions.
Disposal
This product contains the following materials which are harmful to human bodies and
environment.
• Lead, which is contained in solder.

Submenu Functions and Descriptions
Picture Mode
Selects a preset picture mode to suit your operating environment and input signal
picture type.
The preset picture modes are described as below:
• Natural: With well-balanced color saturation and contrast with a low
brightness level, this is most suitable for video images.
• Cinema: With well-balanced color saturation and contrast with a low
brightness level, this is most suitable for enjoying movies in a totally dark
environment (as you would find in a commercial cinema).
• Dynamic: Maximizes the brightness of the projected image. This mode is
suitable for environments where extra-high brightness is required, such
as using the projector in well lit rooms.
• User 1/User 2: Recalls the customized settings. After User 1/User 2 is
selected, some of the sub-menus under the DISPLAY menu can be
adjusted, according to your selected input signal.
User 1 default setting is suitable for video images. User 2 default setting is
suitable for HLG(Hybrid Log-Gamma) contents.
When HDR 10 content such as UHD-BD signal is input to the projector, it
automatically switches to the appropriate picture mode. (*Picture Mode cannot
be switched)
The following functions are only available when Picture Mode is set to User 1 or User 2.
User Mode
Settings
• Load Settings: Selects a picture mode that best suits your need for the
image quality and as a starting point, you can further fine-tune the image
based on the selections listed below.
• Rename User Mode: Select to rename the customized picture modes
(User 1 or User 2). The new name can be up to 9 characters including
English letters (A-Z, a-z), digits (0-9), and space (_).
Brightness
Adjusts the brightness of the picture. When adjusting this control, the black areas
of the picture appear just as black and details in the dark areas are visible.
The higher the value, the brighter the
picture, while the lower the value, the
darker the picture.
Contrast
Adjusts the degree of difference between dark and light areas in the picture. After
adjusting the Brightness value, adjust Contrast to set the peak white level.
The higher the value, the greater the
contrast.
Color
Adjusts the color saturation level - the amount of each color in a video picture.
Lower settings produce less saturated colors; setting to the minimum value
makes the image black and white.
If the setting is too high, colors on the image will be overpowering, which makes
the image unrealistic.
