Taking Care of Your M9020
Location Guidelines
•
Keep the M9020 at least 13 cm (5 inches) away from electrical appliances
that can generate a strong magnetic field such as a TV, refrigerator, motor,
or a large audio speaker.
General Guidelines
•
Do not place heavy objects on top of the device as this may damage the
display.
•
To maximize the life of the backlight in the display, allow the backlight to
automatically turn off as a result of power management. Avoid using a
screen saver or other software that prevents the power management from
working.
Cleaning Guidelines
•
Use a soft cloth moistened with water or a non-alkaline detergent to wipe
the exterior of the M9020.
•
Gently wipe the display with a soft, lint-free cloth. Do not use alcohol or
detergent on the display.
Touchscreen Guidelines
• Use your finger or the included stylus on the display. Using a sharp or
metallic object may cause scratches and damage the display, thereby
causing errors.
•
Use a soft cloth to remove dirt on the display. The touchscreen surface has
a special protective coating that prevents dirt from sticking to it. Not using
a soft cloth may cause damage to the special protective coating on the
touchscreen surface. To clean off hard to remove dirt, blow some steam on
the particular area and gently wipe away using a soft cloth.
•
Do not use excessive force on the display. Avoid placing objects on top of
the display as this may cause the glass to break.
When there is a noticeable discrepancy in the operation of the touchscreen
function (stylus touch does not correlate to the proper location on the screen),
recalibrate the touchscreen display (see “Calibrating the Screen” on page
2-3).
