Chapter 7 Troubleshooting
Clean the Display
A protective overlay can help extend the life of the terminal and make it easier
to clean the display. Table 4 on pag e 17
provides catalog numbers for overlays.
To clean the display, follow these steps.
1. Disconnect power from the terminal at the power source.
2. To clean the display and to prevent scratches, use a clean sponge or soft
cloth with mild soap or detergent.
3. Dry the display with a chamois or moist cellulose sponge to avoid water
spots.
Remove Paint and Grease
Follow these steps to remove paint or grease from the bezel that is properly
mounted in a NEMA, UL Type, or IP rated enclosure.
1. Rub lightly with isopropyl alcohol (70% concentration).
2. To remove residue, use a mild soap or detergent solution.
3. Rinse with clean water.
Equipment Wash Downs
ATTENTION: Do not use abrasive cleaners or solvents, they can damage the
display. Do not scrub or use brushes.
Do not apply cleaning solution directly on the screen of the terminal. The
solution can drip or seep onto the gasket. Apply cleaning solution to a clean
sponge or soft cloth, and gently wipe the screen to remove the dirt and grime.
ATTENTION: Do not use a high-pressure washer for cleaning the front bezel
of the terminal. A high-pressure washer can damage the terminal.
Do not use a high-pressure washer for cleaning vented enclosures. Water can
enter the enclosure and damage the terminal and other equipment.
It is possible for screen objects to activate during equipment wash-downs if the
terminal is turned on.
