Maintenance and Cleaning

This section describes the Maintenance and Cleaning procedures for the Verifone M400. The Verifone M400 has no user-maintainable parts. It can, however, be cleaned.

General Care

Your terminal device is a product of superior design and craftsmanship and should be treated with care. The following suggestions will help you protect your warranty coverage.

• Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can contain minerals that will corrode electronic circuits. If your device does get wet, switch off the power, and allow the device to dry completely before replacing it.
• Do not use or store the device in dusty and dirty areas. Its moving parts and electronic components can be damaged.
• Do not store the device in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.
• Do not store the device in cold areas. Moisture can form inside the device and damage electronic circuit boards when the device returns to its normal temperature.
• Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and fine mechanics.
• Do not paint the device. Paint can clog the moving parts and prevent proper operation.
• Keep the device free from any small and loose items (such as paper clips, staples, or coins) that could accidentally get inside it through an opening, such as the SD card reader slot or the primary smart card reader slot.
• Do not attempt to open the device other than as instructed in this guide. This device has security features that protect it from tampering. For example, the file content will be deleted if the device’s outer casing is opened.

These suggestions apply equally to your terminal device, or any of its attachments or accessories. If your device is not working properly, take it to the nearest authorized service facility for servicing or replacement. For your safety, have this device serviced only by a Verifone-authorized service provider.

Surface Cleaning

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.

Never use thinner, trichloroethylene, or ketone-based solvents – they can deteriorate plastic or rubber parts.

Do not spray cleaners or other solutions directly onto the keypad or display.

Magnetic Card Reader

Dirt accumulation can lead to MSR reading problems unless you clean the Magnetic Stripe Reader (MSR) on a regular basis (daily to once a week, depending on usage). Clean the MSR using commercially available card reader cleaning cards or using recommended Verifone MSR-cleaning card (PN 02746-02).

If using a commercially available cleaning card use ONLY an approved MSR cleaning card made specifically for POS MSR Card reader terminals or Petroleum MSR card readers.

Smart Card Reader

Do not attempt to clean the Smart Card Reader (SCR). Doing so may void any warranty. For smart card reader service, contact your Verifone distributor or service provider.

If you find foreign objects in the SCR, send your terminal to a Verifone authorized repair center.

Do not use Verifone’s recommended MSR-cleaning card (PN 02746-02) or commercially available card reader cleaning cards with the SCR.
