Frequently Asked Questions - CM-407BU DEXP
How do I connect the DEXP CM-407BU mouse to my computer?
Insert the USB receiver into an available USB port. Turn on the mouse by switching the power button on the bottom. The mouse will automatically pair with the receiver. If not, press the connect button on both the mouse and the receiver. The USB receiver is stored in the battery compartment when not in use.
The mouse cursor is not moving. What should I do?
First, check that the AA battery is correctly installed and has power. Ensure the USB receiver is securely connected to a working USB port. Remove obstacles between the mouse and receiver. Try pressing the connect button to re-pair the devices. If the issue persists, restart your computer.
How do I change the battery in the CM-407BU?
Remove the battery cover on the bottom of the mouse. Insert a new AA battery with the correct polarity. Replace the cover and verify that the power switch is on. The mouse will automatically reconnect to its receiver.
Is the CM-407BU compatible with my Mac?
Yes, the mouse works with any device that supports standard USB HID, including macOS. Plug the USB receiver into your Mac and the mouse should work without additional drivers. You can configure button functions in System Preferences > Mouse.
What is the battery life of the mouse?
With normal daily use, the AA battery can last up to 12 months. Battery life varies based on usage patterns, surface, and the number of clicks performed. When the battery is low, the scroll wheel LED may flash or the cursor may become erratic.
How do I clean the mouse?
Use a dry, soft cloth to wipe the exterior and the optical sensor on the bottom. Do not use water or harsh chemicals. For the scroll wheel, gently rotate it while wiping with a cotton swab slightly dampened with rubbing alcohol. Allow it to dry completely before using.
The mouse works only at a short distance. Why?
The effective wireless range is up to 10 meters in open space. However, physical obstacles like metal surfaces or thick walls can reduce the range. Keep the USB receiver in a direct line of sight to the mouse. Also, check for interference from other 2.4 GHz devices, such as Wi-Fi routers or cordless phones.
Can I use the mouse on different surfaces?
Yes, the optical sensor works on most non-transparent surfaces, including wood, plastic, cloth, and paper. For best performance, use a mouse pad with a uniform pattern. Avoid using the mouse on glass or mirror surfaces, as these may cause erratic cursor movement.
How do I download the user manual for this mouse?
You can download the free PDF manual from the notice-facile.com website. Go to the DEXP CM-407BU page, select your language, and click the download button. The manual contains setup instructions, troubleshooting tips, and warranty information.
What should I do if the USB receiver is lost?
Contact DEXP technical support to purchase a replacement receiver. Alternatively, the mouse may support Bluetooth if your model has that feature (check the bottom label). As a temporary solution, you can use a wired mouse or RF receiver from another DEXP device with the same frequency.
