CHAPTER 4
Maintenance
The VX 675 terminal and Base Stations have no user-serviceable parts.
Cleaning the
Terminal
To clean the terminal and Base Station, 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.
Terminal
Contacts
Gently swab the contacts with alcohol or contact cleaner to remove the dirt. It is
important that the exposed contacts of the VX 675 battery stay clean and unbent.
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.
CAUTION
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.
CAUTION
Avoid touching the contacts of the VX 675 battery and the recessed area on the
terminal. Finger oils tarnish contacts, causing bad connections. When operating
on battery power and experiencing a high occurrence of bad or incomplete data
transfers, clean the contacts.
