10.20. Protective film for touchscreen (optional)
An optional protective film is available for resistive touchscreens (all DLT-V83 devices).
This film protects the touchscreen against scratches during extreme use.
NOTICE: Physical damage
Do not attach the protective film to damaged or worn out touchscreens. Air bubbles
can get trapped and cause malfunctions.
The ordered protective film is normally attached to the DLT-V83 touchscreen at the
factory.
If the film must be attached by the customer or replaced:
Turn off the DLT-V83.
Use a neutral glass cleaner without ammonia or isopropyl alcohol applied to a lint-
free cloth.
Wipe off the touchscreen with it.
Then use distilled water to remove any residual glass cleaner.
NOTICE: Physical damage
Never use any kind of chemical solvent, acidic or alkali solution.
Do not use any abrasive glass cleaner or cloths that could scratch the touchscreen.
Make sure that the surface of the touchscreen is free of dust and other particles.
Position the protective film with the adhesive side facing downwards tight at one
corner of the viewing window.
Carefully press on the foil.
Then using a wiper (wooden wiper) to push out any air bubbles to the corners.
