3. Operating Instructions
3.1. Power On/Off
To power on the device, press the main button located on the top of the unit. Press the button again to cycle through vibration modes or to power off the device by holding it down.
3.2. Vibration Modes
The FLIP ZERO EV offers 5 distinct vibration settings: Low, High, Pulse, Alternating, and Random. Press the button on the slide arms to cycle through these modes and find your preferred sensation. Each mode provides a unique pattern of stimulation.

3.3. Vacuum Suction
To enhance sensation, squeeze the pressure pads on the sides of the device. This action creates a strong vacuum suction effect, which can be combined with the core vibrations for an intensified experience. Release the pads to reduce suction.

4. Maintenance
4.1. Cleaning
The FLIP ZERO EV features a flip-open design for thorough cleaning. After each use, open the device and rinse it under running water. The device is completely waterproof, allowing for easy and hygienic cleaning. Use mild soap if desired, and ensure all lubricant residue is removed.
4.2. Drying
After cleaning, the device can be dried by standing it in either of the two shown positions on its stand, allowing for optimal air circulation. It can also accommodate charging while air drying. Ensure the device is completely dry before closing and storing.

The device's flip-open design allows it to be placed on its stand for efficient air drying after cleaning.
4.3. Storage
Store the device in a clean, dry place away from direct sunlight and extreme temperatures. The flip-open design aids in hygienic storage, preventing moisture buildup.
5. Troubleshooting
- Device Not Turning On/Vibrating: Ensure the device is fully charged. If the issue persists, try cleaning the charging contacts and re-attempting to charge.
- Weak Vibrations: Check the battery level and recharge if necessary. Ensure the device is properly assembled after cleaning, as improper assembly can affect vibration intensity.
- Difficulty with Insertion/Too Tight: Apply a generous amount of water-based lubricant to both the interior of the device and yourself. Slowly insert to allow the lubricant to spread evenly. The device is designed for a snug fit, but excessive force should not be required.
- Loud Operation: Some operational noise is normal, especially with vibration. If the noise is unusually loud or accompanied by malfunction, ensure the device is correctly assembled and free from obstructions.
- Latching Mechanism Issues: The plastic latches are designed for secure closure. Handle with care during opening and closing to prevent damage. If a latch breaks, the device may still be usable, but the vacuum seal might be compromised.
