3. Connect: Open your phone's Wi-Fi settings and connect to the network named "AY-201-xxxx" or similar.

• The 1cm Rule: Because this is a macro camera, the image will be blurriest if you are too far away. Keep the tip exactly 1cm to 2cm away from the tooth for perfect focus.

• Anti-Fog: If the lens fogs up due to breath, briefly warm the tip in your hand or use an anti-fog wipe before inserting it into the mouth.

• Hygiene: Always wipe the lens with a 75% alcohol swab before and after use. Use the provided plastic sleeves if sharing the device with others.
