3. Keyboard Functions

The keyboard features a standard alphanumeric layout, function keys (F1-F12), and multimedia keys. Some functions may vary depending on the connected device and its operating system.

• Right Click: Tap with two fingers or use the dedicated right-click button.
• Scrolling: Use two fingers to scroll vertically or horizontally on the touchpad.

Maintenance

1. Cleaning

To clean the keyboard, gently wipe the surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals or excessive moisture, which can damage the internal components.

2. Battery Replacement

When the keyboard's performance degrades or the indicator light signals low battery, replace the two AAA batteries. Ensure correct polarity during installation.

3. Storage

Store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.

Troubleshooting

1. Keyboard Not Responding

• Ensure the keyboard is powered on and batteries are correctly installed and charged.
• Verify the correct connection mode (RF, BT1, BT2) is selected on the keyboard.
• For RF connection, ensure the USB nano receiver is securely plugged into the device. Try a different USB port.
• For Bluetooth connection, ensure Bluetooth is enabled on your device and the keyboard is paired. Try re-pairing the keyboard.
• Move the keyboard closer to the connected device to rule out range issues.

2. Slow Response or Input Lag

• This can sometimes occur with Bluetooth connections, especially if there is interference or if the device's Bluetooth module is busy.
• Ensure no other devices are causing interference (e.g., other 2.4 GHz wireless devices).
• Try connecting via the RF nano receiver if available, as it often provides a more stable connection.
• Ensure your device's operating system and drivers are up to date.

3. Touchpad Not Working

• Ensure the keyboard is powered on and connected.
• Check if the touchpad has been accidentally disabled (some keyboards have a function key to toggle the touchpad).
• Clean the touchpad surface to remove any dirt or debris that might interfere with tracking.

4. Connectivity Issues

• If experiencing frequent disconnections, try re-pairing the Bluetooth connection or re-inserting the RF receiver.
• Ensure your device's operating system is compatible (Windows, Mac, iOS, iPadOS, Android are supported).
