Ensure surface is flat and clutter-free; no direct overhead light.
Confirm correct touch mode (touch vs. pen) is selected.

Other Common Issues

Projected image is blurry

Use the Focus button with +/- to fine-tune. Start by adjusting one direction until blurry, then reverse until sharp.

Why does the screen flicker when recording with a phone camera?

This is a normal physical phenomenon. AiLight’s eye-friendly lighting, spectrum, and flicker rate are not perfectly synchronized with most camera shutter speeds—though it’s completely harmless to the human eye. To resolve it:

Set your camera’s shutter speed to 1/60s;
Use the Blackmagic Cam app (iOS & Android) and ensure its shutter speed is also set to 1/60s.

Will my learning data be lost?

Core progress data (reports, learning history) is securely stored in the cloud—recoverable even after device replacement.
Some local app data (e.g., learning levels) may reset after factory restore—depends on the app. Repeating lessons reinforces memory.
