Problem Solution

(Open Pluggable Specification) standard is
connected to the machine, the control panel
buttons will not work until the controller is
completely shut down. Wait until shutdown is
complete.
The remote control does not work • Check for incorrect battery orientation.
• Check for dead batteries.
• Check your distance and angle from the
machine.
• Check whether remote control is properly
being pointed at the remote control sensor
window of the display.
• Check for any obstacle between the remote
control and the remote control sensor
window.
• Check that the remote control sensor
window is not under strong fluorescent
lighting, or in direct sunlight.
• Check for any devices (computer or
personal digital assistant, PDA) nearby that
transmit infrared signals which may cause
interference to signal transmission between
the remote control and the machine. Turn off
the infrared function of these devices.
An abnormal sound is heard from the area
surrounding the output/input terminals on the
back of the display
Quickly press and release the power button on
the right side of the display. When the machine
shuts down, press the power button again to
restart the machine. If any of these actions do not
fix the problem, contact your service
representative.
