This document provides essential steps for setting up and operating your Hisense 120L5H Laser TV. It covers physical installation, image alignment, remote control pairing, and basic troubleshooting. Always ensure the device is placed on a stable surface with adequate ventilation.

Device description and setup
The Laser TV console features a lens with a laser, eye protection sensor, power button, and air vents. Before powering on, ensure all necessary cables (HDMI, Ethernet, audio) are connected to the rear ports. The device requires at least 20 cm of free space on the sides and 5 cm at the back for proper airflow.

Installation and connection
For optimal performance, follow these steps:

- Place the console on a stable, flat surface.
- Connect the power cord and necessary external devices (e.g., set-top box, game console) to the HDMI ports.
- Connect to the internet via Ethernet cable or built-in Wi-Fi.
- Plug the power cord into a wall outlet and press the power button.
Image adjustment
Use the geometric correction features to align the projected 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 Geometric Correction: Use the remote control navigation buttons to adjust individual points to fit the screen perfectly.
Remote control
To pair the remote, keep it within 3 meters of the console and press any button (except power or mic). If pairing fails, hold the menu button to initiate the process. Ensure batteries are inserted correctly and not mixed with old ones.
Maintenance and safety
- Do not look directly into the lens while the device is on.
- Clean the lens only with professional optical cleaning tools.
- If the device is moved from a cold to a warm environment, wait at least one hour before turning it on to avoid condensation.
- Keep the device away from moisture, dust, and heat sources.
