Operating Instructions
Switching Between Devices
The Rapoo M308 allows you to connect to up to three devices (one 2.4G wireless and two Bluetooth devices) and switch between them.
- Briefly press the mode switch button to cycle through the connected devices: 2.4G (green light), Bluetooth 1 (blue light), Bluetooth 2 (blue light).
- The indicator light will briefly illuminate in the corresponding color to confirm the selected mode.
DPI Adjustment
Press the DPI button (usually located behind the scroll wheel) to cycle through different DPI settings. This changes the cursor speed and sensitivity. The indicator light may flash to show the current DPI level (e.g., one flash for low DPI, two for medium, etc.).
Maintenance
- Cleaning: Use a soft, dry cloth to clean the mouse. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the device.
- Battery Replacement: When the mouse performance degrades or the indicator light signals low battery, replace the two AA batteries following the installation steps.
- Storage: When not in use for extended periods, turn off the mouse to conserve battery life. Store the USB receiver inside the mouse to prevent loss.
Troubleshooting
- Mouse not responding:
- Check if the mouse is turned on.
- Ensure batteries are correctly installed and not depleted. Replace if necessary.
- For 2.4G connection, ensure the USB receiver is securely plugged into a working USB port. Try a different USB port.
- For Bluetooth connection, ensure the mouse is in the correct Bluetooth mode (BT1 or BT2) and successfully paired with your device. Re-pair if needed.
- Cursor movement is erratic or slow:
- Clean the optical sensor on the underside of the mouse.
- Ensure you are using the mouse on a suitable surface (non-reflective, non-transparent).
- Adjust the DPI setting using the DPI button.
- Cannot switch between devices:
- Ensure all devices are properly connected (2.4G receiver plugged in, Bluetooth devices paired).
