Setup Guide
1. Physical Placement
Position the projector on a flat, stable surface or mount it securely. Ensure there is sufficient space around the projector for proper airflow. Adjust the projector's height and angle using the adjustable feet to achieve the desired image position on your screen or wall.
2. Connecting Devices

- HDMI: Connect one end of the HDMI cable to the HDMI port on your source device and the other end to the HDMI input port on the projector.
- Power: Connect the power cord to the projector's power inlet and then plug it into a grounded electrical outlet.
Operating Instructions
1. Powering On/Off
- To Power On: Press the Power button on the projector's control panel or the remote control. The power indicator light will illuminate, and the projector will begin its startup sequence.
- To Power Off: Press the Power button again. A confirmation message may appear. Press the Power button once more to confirm shutdown. The projector will enter a cooling cycle before completely shutting down. Do not unplug the projector during the cooling cycle.
2. Input Source Selection
Use the "Input" or "Source" button on the projector or remote control to cycle through available input sources (e.g., HDMI, VGA). Select the input corresponding to your connected device.
3. Image Adjustment
- Focus: Rotate the focus ring on the projector lens until the image appears sharp and clear.
- Zoom: Adjust the zoom ring on the projector lens to change the size of the projected image.
- Keystone Correction: If the image appears trapezoidal, use the keystone correction function (usually accessible via the menu or dedicated buttons on the projector/remote) to square the image.
- Menu Navigation: Use the menu buttons on the projector or remote to access settings for brightness, contrast, color, aspect ratio, and other display options.
Maintenance
1. Lamp Replacement
The projector lamp has a finite lifespan. When the lamp indicator light illuminates or the image becomes dim, it's time to replace the lamp. Refer to the projector's service manual or contact a qualified technician for lamp replacement procedures. Always use genuine replacement lamps.
2. Air Filter Cleaning
Regularly clean the air filter to prevent dust buildup, which can lead to overheating and reduced performance. The cleaning frequency depends on the operating environment. To clean, remove the filter cover, gently remove the filter, and use a soft brush or vacuum cleaner to remove dust. Reinstall the filter and cover securely.
