How to use

To use the mouse over Bluetooth, enable Bluetooth on your computer or tablet, put the mouse in pairing mode according to the manufacturer's pairing procedure, and select the device from the system Bluetooth list. To use via the USB receiver, insert the receiver into an available USB port; the system should recognize the mouse automatically without additional drivers in most modern operating systems. Replace batteries when cursor responsiveness diminishes or the device indicates low power.

Usage recommendations

For reliable tracking, use the mouse on a flat, non-reflective surface or a mouse pad. When switching between devices frequently, keep the USB receiver accessible and remember to disconnect or re-pair the Bluetooth connection on devices that should not remain linked. Store the mouse in a padded compartment during transport to avoid mechanical wear.
