The voice function needs to be initialized and used online. Use 1. Pay attention to heat dissipation To maintain the performance and reliability of the projector, please leave at least 30cm of space between the projector and surrounding objects. 30cm 30cm 30cm 2. Pay attention to your eyes The projector has high brightness. Please do not look directly or avoid using the projector to illuminate people's eyes, as it may cause vision damage. Functional use Projection method Settings - Projection - Projection Settings - Projection Method Refer to the following figure for reference and debugging 1. Formal front projection 2.lifting front projection Note: 1. When using the lifting method, provided that there is a curtain, the projector cannot be higher than the upper edge of the screen, otherwise it will affect the image effect or trapezoidal correction. 2. It's necessary to install the projector on the symmetrical center line of the screen, with a side and overhead projection angle of no more than 15 degrees, to avoid causing trapezoidal distortion of the projected image. 3. During the installation process, avoid operating with electricity to avoid electric shock hazards or projector circuit malfunctions. 4. When the newly installed projector is turned on for the first time, the image may appear trapezoidal distortion and blurring at the top and bottom. Please refer to the "Projection Settings" settings for adjustment. Functional use 1. Projection setting The new factory projector has made the following presets for several core settings that affect the image There are four projection methods to choose from, including "formal front projection, lifting front projection, formal back projection, and lifting front projection." The preset is " formal front projection". The projection screen can be freely scaled. The preset "autofocus" function is turned on, and the image projected by the projector will be automatically adjusted to the clearest. The preset "automatic trapezoidal correction" function is turned on, and the image projected by the projector will be automatically corrected. To meet the needs of most viewing projector scenes, the "automatic obstacle avoidance" function is preset to be turned off. In situations with a screen, following the prompts can automatically fill the entire screen with the image Note: 1. When automatic trapezoidal correction is turned on, automatic obstacle avoidance can only be turned on. 2. When the automatic entry screen is turned on, the automatic obstacle avoidance cannot be turned on, and the automatic trapezoid will be turned off. 3. The trapezoidal effect of each machine is limited by its angle (horizontal, vertical, rolling angle). If the angle exceeds the limit, the trapezoidal effect becomes abnormal. In this case, it is necessary to follow the previous instructions. Adjust the position of the projector. 4. When triggered, there should be no obstacles blocking the front of the machine camera, which will affect the trapezoidal and focusing effects. If this situation occurs, generally, just trigger it again 2. Obstacle avoidance and entry precautions: Automatic obstacle avoidance requires that obstacles cannot exceed two or more squares on the chessboard on the screen, that is, obstacles cannot be within the red box in the following picture. Precautions: To increase recognition accuracy, please use a screen with a black border. When entering the screen, it is important to ensure that all four corners of the screen are within the white area of the screen, and the corners circled are shown in the following figure. Functional use 3. Manual focusing During the use of the projector, slight movement may cause slight virtual focus. The amplitude of the movement before and after the virtual focus does not trigger automatic focusing of the projector, and manual focusing of the image is required. Press the "F+" or "F -" keys on the remote control to adjust the lens focus. Tap or hold the focus button until the image is clear (as shown below) Focus key 4.WIFI connection Functional use 4.
