Regular Cleaning

7.1.1 Cleaning the Display

When the surface or the frame of the display gets dirty, soak a soft cloth in water
with a neutral detergent, wring the cloth tightly, and wipe the display.
• Do not use paint thinner, organic solvents, or a strong acid compound to clean the unit.
• Do not use hard or pointed objects to operate the touch-screen panel, since it can dam-
age the panel surface.

7.1.2 Installation Gasket Check/Replacement

The installation gasket protects the GP and improves its water resistance. For
instructions on installing the GP's gasket, refer to
A gasket which has been used for a long period of time may have
scratches or dirt on it, and could have lost much of its water resis-
tance. Be sure to change the gasket periodically (or when scratches or
dirt become visible).

3. Changing the Backlight
1) Each of the GP's corners has 4 ribs that
hold the installation gasket in place. Push
the gasket into the side of the GP, so that
it is held by all 4 ribs.
• The gasket is flexible, but not
elastic, and may tear if
stretched too far. Do not
stretch the gasket around
the ribs, only push.
• Be sure the gasket's seam
is not inserted into any of
the unit's corners, only in
the straight sections of the
groove. Inserting it into a
corner may lead to its
Seam eventually tearing.
