3. Setup Instructions

1. Unpack the Cooling Pad: Carefully remove the cooling pad and its accessories from the packaging.
2. Connect Power: Use the provided USB-A to USB-A cable. Connect one end to a USB port on your laptop or a USB power adapter (not included) and the other end to one of the USB ports on the cooling pad. The LED fans should illuminate, indicating power.
3. Adjust Height (Optional): Flip the cooling pad over and extend the support legs to your desired ergonomic angle (5° or 21°). Ensure both legs are securely locked in place.
4. Secure Laptop: Place your laptop on the cooling pad. Pull out the two anti-slip baffles located at the front edge of the cooling pad to prevent your laptop from sliding.
5. Use Phone Holder (Optional): If desired, attach the mobile phone holder to the designated slot on the side of the cooling pad.

4. Operating Instructions

1. Power On/Off: The cooling pad powers on automatically when connected via USB. To turn off the fans, use the speed control switches.
2. Adjust Fan Speed: The cooling pad features two separate rotary switches, typically located on the side. One switch controls the three large fans, and the other controls the three small fans. Rotate the switches to increase or decrease fan speed. Turning a switch fully counter-clockwise will turn off the corresponding set of fans and their LEDs.
3. Utilize USB Ports: The two integrated USB 2.0 ports can be used to connect other USB devices such as a mouse, keyboard, or external hard drive. These ports are for data transfer and power passthrough.
4. Mobile Phone Holder: Place your smartphone in the integrated holder for convenient viewing while working or gaming.

5. Maintenance

• Cleaning: Regularly clean the metal mesh surface and fan blades to prevent dust accumulation, which can hinder cooling performance. Use a soft, dry cloth or compressed air. Ensure the cooling pad is disconnected from power before cleaning.
• Storage: When not in use, store the cooling pad in a cool, dry place away from direct sunlight and extreme temperatures. Retract the support legs and anti-slip baffles for compact storage.
• Cable Care: Handle the USB cable gently to avoid damage. Do not bend or twist it excessively.

6. Troubleshooting

• Fans Not Spinning / LEDs Not Lighting Up:
  • Ensure the USB cable is securely connected to both the cooling pad and a powered USB port.
  • Check if the fan speed control switches are turned up (not at the 'off' position).
  • Try connecting the cooling pad to a different USB port or power source.
  • Verify the USB cable is not damaged.
• Poor Cooling Performance:
  • Ensure all six fans are operating at their maximum speed.
  • Clean any dust accumulation on the metal mesh and fan blades.
  • Ensure your laptop's vents are not obstructed.
  • Position the cooling pad so that its fans align with your laptop's intake vents for optimal airflow.
• Laptop Sliding Off:
  • Ensure the anti-slip baffles at the front of the cooling pad are extended and properly supporting your laptop.
  • Verify the cooling pad is placed on a stable, flat surface.
