5.1 Cleaning the Display
When the surface or frame of the display become 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
damage the panel surface.
