When  the  product  appears  to  be 

malfunctioning

When the mouse pointer on the screen does not 

„

„

move, or moves unstably, when the mouse is moved

 It is possible that the reflectivity of the surface on which 

this product is being used is not suitable for an optical 
mouse. Use this product on a mouse pad that is designed 
for use with optical mice.

When the mouse was connected to the USB port, it is 
possible that the standard Windows mouse driver did 
not install correctly and that this product is detected as 
an unknown device by Windows®. This product is usually 
detected as a USB human interface device. If it is detected 
as an unknown device, see “Removing an unknown device,” 
and after removing the device from Device Manager, 
repeat “Step 2 - Connecting the Mouse” on the front of this 
sheet.

It is possible that the driver is conflicting with another 
driver such as that for a laptop touch pad. To use this 
product correctly, you must delete the touch pad driver. 
However, if you delete this driver, you may not be able to 
use the touch pad or touch pad functions. Contact the PC 
manufacturer for more details.

The wheel moves, but the mouse cursor does not

„

„

In certain applications that do not support the scrolling 

function, the mouse cursor will not move when you move 
the wheel.

When the computer is turned off while the mouse is 

„

„

connected, the optical sensor unit is still illuminated

If a computer uses standby power, an optical sensor may be 

illuminated depending on the computer’s specifications. 
This is due to the design of the computer and does not 
mean that the mouse is faulty. Either disconnect the 
mouse from the computer or disconnect the computer’s 
power cable from the power outlet. Contact the computer 
manufacturer for how to stop the supply of standby power 
to the mouse without removing the computer’s power 
cable from the power outlet. (With some computers it is 
not possible to stop the supply of standby power.)

Removing an unknown device

If the standard Windows mouse driver did not install correctly 
and this product is detected as an unknown device, remove the 
unknown device from Device Manager, and then  repeat “Step 2 - 
Connecting the Mouse” on the front of this sheet.

If there are multiple unknown devices, before 

 

removing a device, check that it is actually this 
product. Disconnect the receiver unit and check 
which unknown device disappears. The device that 
disappears is this product.
If the unknown device does not disappear even 

 

after you have deleted the driver following the 
instructions below, it is possible that there is 
something wrong with the PC. Contact the PC 
manufacturer.

With the product connected to the PC, follow the procedure 
below to remove the unknown device.
