headphones) is used near the Display. Move the
infrared communication equipment away from the
Display until the noise is eliminated
Possible Solution
• You may use the super password (2580).
• If a setting option appears in gray, this indicates that
the settings option is unavailable in current input
mode.
• When the Display is in use, there is a natural rise
in temperature, causing the cabinet to expand
or contract and may be accompanied by a slight
creaking noise. This is not a malfunction.
• During the timing of USB device detection (i.e. when
the Display is turned on with USB device connected,
or when you plug in USB device during Display
working),the Display may not act by remote control
buttons in such case. Wait some time, then it is OK.
• Disconnect the power cord and wait for a few
seconds. Then re-plug the power cord and turn on
the Display again
