Dimensions of the desk:
- Mobile desk: W2, H3, and L2
- Immobile desk: W2, H3, L2 and W1 (need to leave enough space to move the device on the desk) 4) Image of the projection The wall for the projection should be larger than the area of your desired image size.

192.3cm / 75.7in. 3) Area of the desk (L2 x W2): 53.3 x 55cm / 21.0 x 21.7in. 4) Area for the wall (L3 x H4): 221.4 x 192.3 cm / 87.2 x 75.7in. 1) Conversion figures may have been rounded up or down. 2) Leave plenty of space around and under the projector for ventilation, and keep the vents unblocked in all directions. 3) Position the projector within reach of a grounded electrical outlet or extension cord. 4) The image size increases as the projector gets farther from the wall. Please move the desk for placing the projector as the distance requires. 5) For H3, a recommended value is provided for a better experience since you would feel it comfortable watching from the sofa when the image center is at 1.3m / 51.2in high. You can change it as per actual needs. INSTALLING THE PROJECTOR Place the projector on the desk, move to the appropriate distance for the desired image size when keeping the device in parallel with the wall. Connect the projector to power, press the Power Button on the device or remote to turn it on. Follow the instructions to go through the wizard, including the following operations:
1) Pair with remote control 2) Choose a language 3) Network settings 4) Select the installation method 07/08 FUNCTIONS 1. MOTION DETECTION There are two PIR motion sensors at the front of the projector; when it detects human approaching, the projector will lower the brightness of the laser light in case of any harm to our eyes.

ROUTINE MAINTENANCE Please wipe clean the shell and top cover of the projector routinely with the cleaning cloth equipped or others for professional use. Do not apply abrasive detergent, solvent or other coarse chemicals to avoid scrapes. Before cleaning, unplug the power cord from the socket. Leave plenty of space around the vents for heat dissipation. Do not place anything blocking the speaker for better sound. Dismantling the device will not only fail the warranty but may also cause harm to your or others safety.

The principle of the ALPD technology?
Throw ratio and ultra-short throw?
Need to prepare a screen?
For its beautiful color, high brightness, and long life. Advanced laser-powered phosphor display
(ALPD) is a large-format display technology and the critical technology for laser display. With laser and luminescent material made of rare earth, it can provide a high color gamut for laser TVs, up to 90% of that for human eyes, which is far higher the 62% of the LED products performing the best in this aspect on the market currently. The most updated laser source technology ALPD3.0 improves the efficiency by the optical design and the reliability by the structure design and material development. The light source has a super long life span of 20,000 hours, and has been used accumulatively for 100,000 hours. Throw ratio is the ratio of the distance from the lens to the screen to the screen width. The smaller the ratio is, the larger screen it can be with a same distance. For example, for a 100 SD image, a ratio of 0.233 needs a distance of 516mm between the lens and the screen, when a 1.00 ratio needs 2215mm. A projector with a throw ratio lower than 0.3 can be regarded as an ultra-short throw one. A screen is not a must. The projector can be used for any flat surface. For better performance, please apply to a flat wall with only one color, and a white wall is preferred. Also, using a recommended screen can provide the best experience. Motion detection not working?
Support 3D function?
Make sure the sensor is not blocked and the function is active in settings. Yes, you need a pair of DLP Link 3D glasses. Remote control not working?
Cannot play files in the USB drive?
No signal after connecting a device by the HDMI port?
No sounds?
Not clear image?
Keystone correction function?
How to choose the audio output?
1) Make sure the remote is loaded with batteries energized;
2) On the Bluetooth setting interface, check whether the remote is connected; otherwise, connect it again. 1) It may be of invalid format that the projector does not support. 2) Backup the files to your computer, format the USB drive, transfer the files back to the drive, and plug the drive into the projector to play again. There are 3 HDMI ports on the projector. Please make sure you connected to the correct one, the HDMI wire is good, and the HDMI device is power on. Check whether the correct audio output (built-in speaker / external speaker) is selected for audio setting, and whether its muted. 1) Make sure the video is high definition originally. 2) Check the projector is in focus: go to Settings
-> Display -> Electric Focus to adjust the focus. Supports improving the image distortion problem by software; but the function can only work to some degree and will impact the clarity of the image. Therefore, youre recommended to eliminate or reduce the distortion by physical means. When connecting to a speaker, in the settings you can see two output options: PCM and RAW. 1) For PCM output, the audio source is decoded. It features wide compatibility, meaning working with almost all types of speakers; but the sound quality would be compromised. 2) For RAW output, no decoding is involved for the audio output, thus retaining the original sound (as long as the speaker connected supports the decoding of the audio). Generally RAW output is the optimal choice. 23/24 TROUBLESHOOTING Problem Solution The device cannot show image or theres an anomaly. Android system just broke down. Remote control got disconnected;
or cannot power on the device wireless because its not paired. The system prompts a message of high temperature and the device shuts off automatically. The device cannot be powered on. Android system is stuck. Power off the device, unplug the power cord. Plug it again after 1min and power on the device. Power off the device, unplug the power cord. Plug it again after 1min and power on the device. Power off the device, unplug the power cord. Plug it again after 1min and power on the device with the button on the device. Then press the Return and Menu buttons at the same time to pair the remote again. Make sure the device is working in a proper ambient temperature (within the devices working temperature range) and that the vents are not blocked. Restart the device. Check whether the device is connected to power properly and that the socket connects to electricity. Press the Power button on the device to start. 1) Too many system cache: please free up space on Android and delete rarely used apps. 2) Network problem: check whether your network supports watching video online; theoretically, a bandwidth of 8M or higher can provide 1080p videos without getting stuck. 3) Power off the device, unplug the power cord. Plug it again after 1min and power on the device. WARRANTY We will provide you with after-sales service based on specific local policies.
