CHAPTER 8
Maintenance
The VX 520 terminal has no user-maintainable parts.
Clean the
Terminal
To clean the terminal, use a clean cloth slightly dampened with water and a drop
or two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.
Smart Card
Reader
Do not attempt to clean the smart card reader. Doing so may void any warranty.
For smart card reader service, contact your VeriFone distributor or service
provider.
Never use thinner, trichloroethylene, or ketone-based solvents – they may cause
deterioration of plastic or rubber parts.
Do not spray cleaners or other solutions directly onto the keypad or terminal
display.
