Adjusting Touch Panel Angle
You can slide the touch panel to adjust the angle so that it is easy to
use.
Use of a touch panel protection sheet is recommended if this product is
used in an environment where users' hands are easily soiled by sand,
dirt, etc.
CAUTION:
Do not place heavy objects on the touch panel. The touch panel may
be damaged because it uses glass.
Do not push or scrub the touch panel. Also, do not push it with a sharp
pointed object.
