• Please use the projector with a soft brush. Do not use rigid accessories, such as a crevice cleaning tool, to avoid damage to the projector.

Notes on Fire and Electric Shock

• Make sure of adequate ventilation and blocked outlet to avoid heat accumulation within the projector.
• Prevent foreign objects from falling into the projector, such as paper clips and paper scraps, do not attempt to retrieve any such object Do not insert any metal object, such as an iron wire or a screwdriver, into the projector. Make sure to immediately turn off the power and ask qualified professional maintenance personnel to remove any object falling into the projector.
• Do not place any liquid on the projector.

Moving

• Please use soft package materials and attach the lens cover to protect the lens when moving the projector. Also, do not impose severe mechanical vibration on the projector.

High Temperature Warning

• During and after the projection, the temperature near the outlet will rise, therefore touching may cause burns. Do not peep at the lens, or it may cause severe eye injury.

Installed Away from Walls

• Please leave at least 30cm from the wall to maintain the projector’s performance and reliability.

Names and Functions of Projector Components

Equipment Connection and Equipment

Attentions:
Noise or image quality degradation may occur due to using a cable longer than that supplied with the product,or extending the RGB cable.We recommend to use a noise eliminator or other devices for long cables. Please consult with the installer or other professionals.
To obtain the clearest video,set the personal computer’s output frequency to 60 Hz.

Technical Points

What ‘ s RGB Port ?
The Port sends the video signal to a monitor or other devices . Three colors , R ( Red ), G ( Green ) and B ( Blue ), are respectively independent and transmitted as analogsignals by the system . What the personal computer displays is represented by RGB color space . All colors can be reproduced by the combination of the three colors .
These Ports mainly use mini D – Sub 15-core standard , which stipulates their shapes , while the control signals and others for signal synthesis are in synchronous transmission with RGB color signals .
What frequency are supported ?
The supported frequency is a term , indicating the scanning frequency width supported by the projector . Scanning frequency is the speed of the display drawing the screen .  he number of lines drawn in a second is called horizontal scanning frequency , and the number of screens redrawn in a second is called vertical scanning frequency . The more the scanning frequency , the higher the resolution , the more the number of colors expressed at the same time , and the less liable the display fiickers . For example , the display With the vertical scanning frequency of 70 Hz can draw 70 times of screen in a second .
Attentions:
The projection image may be incorrect though the image on LCD is correct as both the laptop LCD and the projector are displaying images . Please stop the synchronous display of the laptop and try only external output display in this case .
:Signal Flow Direction

Equipment Connection and Materials

There are various output modes of external output signals, depending on the personal computer manufacturer. See the following table for details.

Attentions:
Note: The contents in the above table was last updated in April 2016, refer to the actual contents in the computer manual.

Get to Know the Remote Control

Attentions:
Please be careful when operating the remote control .
Do not drop or tread on the remote control , or splash any kind of liquid into the remote control .
Do not place the remote control near a heat source , n a place exposed to direct sunlight or in a damp room .

How to Install and Debug a Projector Quickly

Installation and Debugging

1. Install the Projector
   You can choose to place the projector on the horizontal place or attach it to a hanging bracket. ! Attentions:
