3.2 Mouse DPI Adjustment
The mouse offers three adjustable DPI (Dots Per Inch) levels to control cursor sensitivity: 800, 1200, and 1600 DPI. This allows you to customize the mouse's responsiveness to your preference.
- To change the DPI, press the DPI button (usually located near the scroll wheel). Each press will cycle through the available DPI settings.

4. Maintenance
4.1 Cleaning

- Ensure no liquid enters the device openings.
4.2 Battery Care
- Charge the devices regularly to maintain optimal battery health.
- Avoid fully discharging the battery frequently.
- Store the devices in a cool, dry place when not in use for extended periods.
5. Troubleshooting
5.1 Keyboard/Mouse Not Connecting
- Check Power: Ensure both the keyboard and mouse are turned ON and have sufficient battery charge. Recharge if necessary.
- Re-pair Bluetooth:
- Turn off the device's Bluetooth.
- On your host device (iPad, tablet), forget or remove "Bluetooth 3.0 Keyboard" or the mouse from your Bluetooth device list.
- Restart your host device.
- Turn on the keyboard/mouse and put it into pairing mode (press CONNECT for keyboard, switch to Bluetooth mode for mouse).
- Turn on Bluetooth on your host device and attempt to pair again.
- 2.4G Mouse Connection: If using the 2.4G USB receiver for the mouse, ensure the receiver is securely plugged into a USB port and the mouse is switched to 2.4G mode. Try a different USB port.
