Safety Information
- UV-C Light Safety: The UV-C self-cleaning function is designed to operate only when the bottle cap is securely closed. Do not attempt to activate the UV-C light when the cap is open, as direct exposure to UV-C light can be harmful to eyes and skin.
- Temperature Warnings: The touchscreen displays the water temperature. Pay attention to the color-coded ring: Blue (<35°C/95°F) indicates cool, Orange (36-50°C/97-122°F) indicates warm, and Red (>50°C/122°F) indicates hot. Exercise caution when consuming liquids indicated by an orange or red ring to prevent burns.
- Charging: Use only the provided magnetic charging cable. Ensure the charging port is dry before connecting the cable.
- Cleaning: The bottle is designed for hand washing only. Do not immerse the cap in water or place it in a dishwasher, as this may damage electronic components.
- Intended Use: This bottle is intended for water and other non-carbonated, non-acidic beverages. Do not use with carbonated drinks, dairy products, or fruit juices, as this may affect the self-cleaning function or bottle integrity.

3. Filling the Bottle

Operating Instructions
1. Power On/Off
The bottle's display automatically activates when touched or when the bottle is moved. There is no manual power on/off button for the display itself; it enters a low-power state when inactive.
2. Checking Water Temperature
Gently tap the touchscreen on the cap. The current water temperature will be displayed in Celsius, accompanied by a color-coded ring indicating the temperature range:
- Blue Ring: Water temperature is 35°C (95°F) or below.
- Orange Ring: Water temperature is between 36°C (97°F) and 50°C (122°F).
- Red Ring: Water temperature is above 50°C (122°F). Exercise caution.

The VSITOO S1 Pro features AI self-cleaning that learns your hydration rhythm and activates cleaning during natural downtime. You can also manually activate it:
- Ensure the bottle cap is securely closed.
- Long press the touch-sensitive area on the cap. The UV icon will begin to flicker, indicating that the self-cleaning function has been activated.
- The cleaning cycle typically lasts for a short period, using UV-C light to eliminate up to 99.9% of germs.
