Operation
Touchscreen
The touch screen is a high-resolution colour screen that
responds to finger touch. Please note that light pressure is fully
adequate to achieve the desired reaction.
Although the screen is very robust and long-lived, please ensure
that it is not scratched and that it does not get into contact with
corrosive fluids (e.g. Chloriliquide (Sodium Hypochlorite), pH-
Plus, pH-Minus, Bayrosoft
®
etc.).
To clean the screen, use a mild cleaner on a soft cloth. Always
wipe it with a damp cloth after cleaning.
Do not touch the screen of the device with anything else but the
finger. Any contact with other objects such as pens, knives or
nails may cause scratches or other damages of the surface.
Any damage caused by misapplication will result in loss of
warranty!
