Operating Instructions
1. Powering On/Off
- Press the Power button on the projector or the remote control to turn the unit on.
- Press the Power button again to turn it off.
2. Selecting Input Source
After powering on, use the Source button on the projector or remote control to cycle through available input sources (HDMI1, HDMI2, HDMI3, USB, SD, AV, VGA, YPbPr, TV).
3. Adjusting Focus and Keystone
- Focus: Rotate the lens ring on the front of the projector until the projected image is clear and sharp.
- Keystone Correction: If the image appears trapezoidal (wider at the top or bottom), use the keystone adjustment knob (usually on the top or side of the projector) to correct the vertical distortion. The H3 supports manual vertical +/- 15 degrees keystone correction.
4. Menu Navigation
Press the Menu button on the projector or remote control to access the on-screen display (OSD) menu. Use the arrow keys and OK button to navigate and adjust settings such as picture mode, sound, aspect ratio (4:3 / 16:9), and image rotation (H/V).
5. Media Playback (USB/SD)
When a USB drive or SD card is inserted, the projector can play various media formats including RMVB/MPEG4 and H.264 video. Navigate to the USB/SD input source and select your desired file.

Maintenance
1. Cleaning the Lens
Use the provided lens cleaning cloth or a soft, lint-free cloth specifically designed for optical lenses. Do not use abrasive cleaners or solvents. Gently wipe the lens in a circular motion to remove dust or smudges.
2. Cleaning the Projector Body
Wipe the exterior of the projector with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the ventilation openings.
3. Ventilation
Ensure that the ventilation windows are not blocked during operation. Proper airflow is crucial for dissipating heat and extending the life of the LED lamp. The projector features dustproof windows to minimize dust accumulation.
4. Lamp Life
The LED lamp in your Uhappy H3 projector has an estimated life of approximately 50,000 hours, significantly reducing the need for frequent lamp replacements. This contributes to energy saving and environmental protection.

Troubleshooting
No Power
- Check if the power cable is securely connected to both the projector and the electrical outlet.
- Ensure the power outlet is functional.
- Verify the fuses (two spare fuses are included in the package). If a fuse is blown, replace it with a new one.
No Image / "No Signal" Message
- Confirm that the correct input source is selected (e.g., HDMI1, VGA, AV).
- Check the connection cable between the projector and the source device. Ensure it is securely plugged in at both ends.
- Ensure the source device (e.g., laptop, DVD player) is powered on and outputting a signal.
- Try a different cable or input port if available.
Blurred Image
- Adjust the focus ring on the projector lens until the image is sharp.
- Ensure the projection distance is within the recommended range (25" - 250", best at 40" - 120").
- Clean the projector lens if it appears dirty.
Trapezoidal Image
- Adjust the keystone correction knob on the projector to square the image.
No Sound
- Check the volume level on both the projector and the source device.
- Ensure audio cables are correctly connected if using AV or YPbPr inputs. HDMI carries both video and audio.
- If using external speakers, ensure they are properly connected and powered on.
