Troubleshooting
Question: My keyboard is not working. What should I do?
Answer: Check if the receiver is plugged in correctly to your computer's USB port. A loose connection may
result in the computer not being able to detect the device.
If your keyboard is connected to a hub or multi-port USB connector, unplug the device and plug it directly into
your computer's USB port, ensuring there is no interference caused by these devices.
Other system devices, such as PC cards, may cause conflicts that prevent your keyboard from working
properly. Check the settings of these devices and make any changes as necessary. Reboot your computer
and re-attach the keyboard.
Question: The keyboard pointer is moving abnormally. What should I do?
Answer: The likely cause of this problem is debris around or on the lens which is interfering with the optical
signal. Clean the keyboard lens with a cotton swab. Do not use any other materials or solvents to clean the
keyboard lens as this may result in damage to the lens.
If the keyboard pointer continues to move abnormally after cleaning, re-install the drivers and software.
