SYMPTOM ACTION
Check POWER indicators on the
Transmitter and Receiver. They should be
lit. If not, check the wall mount power
supply and the extension cable going from
the Transmitter to the Receiver.
Ensure that the Transmitter's video input
cable is plugged into the computer.
Ensure that the monitor's video cable is
plugged into the Receiver, that the monitor
is plugged into an AC outlet and that the
power is turned on.
Ensure that both ends of the extension
cable between the Transmitter and
Receiver are firmly seated.
Have qualified personnel check AC power
polarity and grounding at both the
computer and monitor.
Ensure that the keyboard cables are
plugged into the proper jacks and then
reboot the computer.
Re-test the keyboard by plugging it directly
into the computer. If the keyboard still
does not operate, the motherboard fuse
has probably blown and must be replaced
by qualified personnel. Verify this by trying
a known good keyboard.
Compare the power requirements of your
keyboard to the Specifications chart in this
User Guide. If LongView cannot provide
enough power for your keyboard, contact
Cybex Technical Support.
