Troubleshooting
Solution
After pressing the connect
button on the transceiver,
the LED will begin flashing.
Within 1 minute, press the
connect button on the
Bluetooth keyboard and/or
Bluetooth mouse. (You must
press the connect buttons
on the transceiver, mouse,
and keyboard for at least 2
seconds.) After pairing is
complete, the Bluetooth
keyboard and/or mouse
are operating in USB
wireless mode.
Once the connect button
has been pressed on the
transceiver, it will wait 1
minute to attach to a
Bluetooth keyboard and/or
mouse.
Once the connect button
on the keyboard or mouse
is pressed, the transceiver
pairs with it and is waiting
for the second device
during the remainder of the
1 minute interval.
If the 2nd device is found
within the 1 minute interval,
the blinking will stop and
the LED will turn solid since
both devices are
discovered.
Download a new firmware
update file and use the new
file to update the firmware.
