Operating Instructions
1. Power On/Off
Press the power button on the projector or the remote control to turn the unit on or off.
2. Adjusting Focus (Electric Focus)
The AY3 features electric focus for clear images. Use the dedicated focus buttons (F+ / F-) on the remote control to adjust the image sharpness. This allows for quick adjustments without physically moving the projector.

3. Auto Keystone Correction
The projector automatically corrects vertical trapezoidal distortion, ensuring a straight and sharp image within approximately 3 seconds. Manual vertical correction is also possible via the remote control.

Maintenance
1. Cleaning the Lens
Use a soft, lint-free cloth specifically designed for optical lenses to gently wipe the projector lens. Avoid using abrasive cleaners or cloths that could scratch the lens.
2. Cleaning Vents
Regularly check and clean the projector's ventilation openings to prevent dust buildup, which can affect performance and lead to overheating. Use a soft brush or compressed air to remove dust.
3. Storage
When not in use, store the projector in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, consider using the original packaging or a protective case.
