Troubleshooting
The response of the touch panel is slow.
Some parts of the screen do not respond.
A different place is touched.
• Isthescreenexposedtodirectsunlightorotherstrong
light? The touch panel uses infrared rays and thus may not
operate correctly.
• Isthereanobstaclebetweentheinfraredtransmitter/
receiver and the touch pen or your finger? An obstacle will
prevent correct operation. If your fingers or a sleeve are too
close to the screen, correct operation will not be possible.
• Istheinfraredtransmitter/receiverdirty?Gentlywipeoff
any dirt with a soft cloth.
• Ifthetouchpanelistouchedwithasmalltiplessthanabout
5/16 inch (8 mm) x 5/16 inch (8 mm), the touch may not
be detected by infrared and correct operation will not take
place.
• WhenstartingyourcomputerorconnectingtheUSBcable,
do not touch the touch panel. If you touch the touch panel,
this may be detected as an element failure in the infrared
transmitter/receiver and incorrect operation will result.
The monitor makes a cracking sound.
• Youmayoccasionallyhearacrackingsoundfromthe
monitor. This happens when the cabinet slightly expands
and contracts according to change in temperature. This
does not affect the monitor’s performance.
