Installation and Ventilation
Proper installation is critical for performance and safety:
- Ventilation: Ensure at least 20 cm of free space on the sides and 5 cm on the back for air circulation. Do not block air vents.
- Mounting: Use only manufacturer-recommended cabinets or stands. Never place the unit on unstable surfaces.
- Power: Connect to a mains socket with a protective earthing connection. Ensure the power plug is easily accessible.
Adjusting the Projected Image
The Laser TV includes geometric correction features to align the image with your screen:
- Auto Geometric Correction: Use the mobile app to scan the QR code and follow on-screen instructions to align the grid.
- Manual Correction: Use the remote control to adjust focus and position points to fit the projected image into the screen frame.
- Levelling: Use the levelling feet to adjust the console height and angle until the image is parallel to the screen.
Remote Control Usage
The remote control uses infrared for standard operation and Bluetooth for advanced features. To pair the remote, keep it within 3 meters of the Laser TV and press any button (except power and mic). If the remote is unresponsive, check the batteries and ensure they are installed correctly.

Troubleshooting: If you experience issues, try turning the device off and on again. Check all cable connections, ensure the antenna is positioned correctly, and verify that the input source is selected properly. If the picture is black and white, unplug the device for 60 seconds and check color saturation settings.
