Q: 

The mouse cursor can only move left & right during operation (it could 

be caused by low battery or the optical sensor’s data error).   

y

 

A: 

Please take out one of batteries and put it back for a power reset and 

then redo the connect procedure.   

y

 

Q: 

The mouse does not work after waking up from power off mode by 

pressing the connect button once.   

y

 

A: 

This might be caused by imprecisely depressing the connect button to 

wake up the mouse. Users can gain back normal operation by pressing 
connect button on the mouse first, and then pressing the one on the 
receiver. As soon as the LED inside the receiver starts flashing, the 
mouse is ready to operate.

not function on reflective, reflective pattern or non-visible detail surfaces! 

 

2. Reducing Interference with Other Wireless Devices 

 

y

  Reducing Interference with Other Wireless Devices: All 27MHz 

radio-based devices are subject to interference from other 27MHz 
radio-based devices, such as cordless telephones, cordless baby monitors, 
and cordless toys. It may help to move the receiver unit and the base unit 
of other wireless devices (such as cordless telephone cradle) as far apart 
as possible. You may need to try several times for a location that is best in 
your operating environment.   

y

  Move the receiver and the mouse closer to each other so that the 

receiver is relatively shorter in distance to the mouse than to other 
27MHz transmitters. You may need to re-establish the “connection”.   

Note:

 Avoid using this device on a metal surface because a large surface of iron, 

aluminum, copper, or other metal may act like a shielding to the RF antenna of 
the mouse and the receiver.   

3. Interference with other RF wireless mouse 

 

If the interference comes from other same model of RF wireless mice, please 
“Setting up connection between mouse and receiver” of the installation guide 
to switch to a new RF channel. A new identification code is also generated
