Important Information

This Laser TV is designed for video and audio signal rendering in home or office environments. For your safety and optimal performance, read all instructions before installation. The device uses a laser module; do not look directly into the lens while the device is on, as laser light may damage your eyes.

Installation and Setup

Safety Precautions:

• Ensure the device is placed on a stable surface.
• Maintain at least 20 cm of free space on the sides and 5 cm on the back for proper ventilation.
• Do not block air vents or place the device in narrow, enclosed spaces.
• Connect all cables (HDMI, Antenna, LAN) to the ports on the back before positioning the unit.
• Two people are recommended when moving the device to protect the lens.

Connections:

• Connect the power cord to a wall outlet and press the Power button.
• Use the provided USB extension cable for easier access to USB ports.
• For network connectivity, use the LAN port or the built-in Wireless LAN Adapter.

Adjusting the Projected Image

The Laser TV features geometric correction to align the image with your screen:

• Auto Geometric Correction: Ensure the device and your mobile device are on the same wireless network. Use the levelling feet to position the unit, then scan the QR code on the screen with your mobile device to start the automatic process.
• Manual Geometric Correction: Use the remote control buttons to select and adjust points to fit the image to the screen.
• Physical Adjustment: Use the wrench to rotate the feet to adjust the height and tilt of the console until the image is parallel with the screen.

Remote Control

Battery Installation: Slide the back cover open, insert two AA or AAA batteries, and close the cover. Do not mix old and new batteries or different battery types.

Pairing: After powering on, keep the remote close to the Laser TV and press any button (except power and mic) to pair. If pairing fails, press and hold the Menu button.
