keyboard. Then quickly press and hold the keyboard’s ESC key
for at least 5 seconds. This allows the keyboard to select a

USB wireless transceiver. This allows the transceiver to detect
the selected frequencies (channels) of the keyboard and
mouse.
If either the mouse or keyboard does not work, both devices may
have inadvertently selected the same channel. Try to repeat the
above steps and try to enable the mouse before the keyboard
instead. You may need to attempt this a few times before both
devices function correctly.
Note: The wireless set works in the same frequency range as your microwave,
wireless phone, and/or other wireless devices such as IEEE802.11b. Adjacent radio
interferences may severely affect the quality of signals. Try to isolate and minimize
the source of interference. Try to select a different channel if either device’s
performance is less than satisfactory.
