Maintenance
The e315 device has no user-maintainable parts.
Cleaning the
Device
To clean the device, 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.
Device Contacts
Gently swab the contacts with alcohol or contact cleaner to remove the dirt.
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 device

Avoid touching the recessed area on the device. 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.
