4. Setup and Installation
4.1 Attaching the Cooler
The MEMO CX08 PRO offers two methods for attachment:
- Magnetic Suction: For devices with built-in magnetic attraction (e.g., some iPhone models) or when using the included magnetic plate. Simply align the cooler with the back of your device until it securely attaches.
- Spring Clip: For devices without magnetic capabilities or for added security. Extend the spring clips and attach the cooler to the sides of your mobile phone or tablet. The cooler is compatible with devices ranging from 62-105mm in width.

4.2 Power Connection
Connect the cooler to a power source using the provided Type-C USB cable. For optimal cooling performance, a power supply of 9V/2A or above is recommended. Below this specification, the cooler may not achieve its full cooling potential.
5. Operating Instructions
- Attach the cooler securely to the back of your mobile phone or tablet using either the magnetic or spring clip method.
- Connect the cooler to a 9V/2A (or higher) power source via the Type-C USB port.
- Turn on the power switch (if applicable, or it may activate automatically upon power connection) to initiate cooling.
- Adjust the fan speed as needed for your cooling requirements.
The cooler will immediately begin to reduce your device's temperature, providing a "frozen" sensation on the contact surface. The RGB lighting will also activate, indicating operation.

6. Precautions
- This device is intended for mobile phone and tablet use only. Do not use with other devices.
- Ensure adequate ventilation around the cooler during operation to maximize efficiency and prevent heat buildup.
- Unplug the power cord when the cooler is not in use for extended periods.
7. Maintenance
To ensure optimal and long-lasting performance of your MEMO CX08 PRO cooler, regular cleaning of the fan is recommended.
- Open the Cover: Gently rotate the upper circle of the cooler to the left to open the cover.
- Access the Fan: Insert the clip buckle end into the designated slot to fully expose the fan.
- Clean the Fan: Use a soft brush or compressed air to remove any accumulated dirt, dust, or hair from the fan blades and surrounding areas. This will help restore optimal heat dissipation performance.
- Reassemble: Once clean, reattach the cover by aligning and rotating it back into place until secure.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cooler not operating | Loose or improper power connection. | Check whether the power connection is secure and the cable is properly inserted. Ensure the power source meets the 9V/2A requirement. |
| Insufficient airflow or cooling | Fan speed too low; dust accumulation; inadequate power supply. | Try switching to a higher fan speed setting. Clean the fan as described in the Maintenance section. Verify power supply is 9V/2A or above. |
| Excessive noise during operation | Excessive dust accumulation inside the fan; obstruction. | Clean the fan thoroughly to remove any dust or obstructions. If noise persists, contact customer service. |

10. User Tips
- For maximum cooling, ensure the cooler is firmly attached to the back of your device, making good contact with the cooling plate.
- While the cooler specifies 9V/2A, using a higher amperage charger (e.g., 20V=2.25A) is generally acceptable as the device will only draw the current it needs, provided the voltage is compatible. Always ensure your power adapter is compatible and certified.
- If using the magnetic attachment, consider using the included magnetic plate for non-magnetic phones to ensure a strong and stable connection.
- Regularly check the fan for dust buildup, especially if you notice a decrease in cooling efficiency or an increase in noise.
