Precaution
!
!!
! The optical mouse can not work on a glass or mirror surface. Avoid operating this
mouse on a glossy surface; otherwise, this mouse may not operate normally.
!
!!
! For consideration of saving battery power, it is strongly recommended to operate an
optical mouse on a bright surface with fine texture to obtain lower power
consumption of the high illumination LED. A very dark surface will cause higher
power consumption.
!
!!
! For optimal performance, mouse should be no more than 5M away from receiver.
!
!!
! For a better transmission distance, avoid using this device on a metal plate or
desktop because a large surface of iron, aluminum, copper and other metal will act
as a shield or ground to the RF antenna of the mouse and receiver. Operating on a
metal surface may shorten the transmission distance.
!
!!
! If your notebook computer has a metal (contains Al or Mg) case, the metal housing
of the LCD panel will isolate partial radiation of the RF signal from the mouse. This
could possibly result in reducing the distance of transmission when you operate the
mouse right in front of the notebook and when the receiver is connected on the back
of the notebook. However, the RF mouse should work properly while you are
operating the mouse just beside your desktop computer.
