13 Precautions
• Do not connect the AC Power Cord to a voltage transformer or inverter.
Connecting the AC Power Cord to a voltage transformer for overseas travel
or an inverter for use in an automobile may cause heat to build up in the AC
Adaptor and may cause burns or a malfunction.
LCD screen
• Red, blue or green spots (bright spots) or black spots (dark spots) may appear
in certain locations on the LCD screen. The appearance of such spots is a
normal occurrence associated with LCD screens and is not a sign of a
malfunction. LCD screens are made using highly precise technology.
However, a very small number of dark pixels or continuously lit pixels exist
on each screen. Also, a distorted image may remain on the screen for several
seconds after the system has been turned off.
• Direct exposure to sunlight may damage the system's LCD screen.
• When using the system in a cold environment, you may notice shadows on
the graphics or the screen may appear darker than usual. This is not a
malfunction, and the screen will return to normal when the temperature rises.
• Do not leave still images displayed on the screen for an extended period of
time. This may cause a faint image to be left permanently on the screen.
