Maintenance
Cleaning
The LELO SONA 3 Cruise is 100% waterproof, making it easy to clean. After each use, wash the device with warm water and a mild, toy-safe soap or a specialized toy cleaner. Rinse thoroughly and pat dry with a lint-free cloth.
Storage
Store your device in the provided satin pouch in a clean, dry place away from direct sunlight and extreme temperatures. Avoid storing it with other toys made of different materials to prevent damage or degradation.
Troubleshooting
- Device Not Turning On or Holding Charge: Ensure the device is fully charged for the recommended 2 hours before use. If the issue persists, verify the charging cable and power source are functioning correctly. If problems continue, contact customer support.
- Unusual Noise During Operation: If you hear a 'slurping' sound, it may indicate incorrect positioning or pressure. Adjust the device's placement and apply firm but relaxed pressure to resolve this. The device is designed to be quiet when used correctly.
- Cruise Control Behavior: The Cruise Control feature automatically increases intensity when pressed firmly against the body to maintain a consistent experience. This may result in noticeable jumps in intensity. If you prefer a more constant low setting, you may need to adjust pressure or cycle through modes to reset the intensity.
- Over-sensitivity After Use: Some users may experience temporary over-sensitivity. If this occurs, allow sufficient time for your body to adjust before next use. Consider using lower intensity settings.
