Device Does Not Start / Does Not Display Correct Readable Information

If the device does not start:

• Ensure that the device is plugged in to a dedicated power source.
• Verify all the cable connections including the proper insertion of the power cable connector.
• If the problem persists, reach out to your local Verifone representative for assistance.

Battery Does Not Charge

The Verifone Carbon Mobile 5 battery must initially receive a full charge to ensure proper operation.

NOTE

• Allow the Verifone Carbon Mobile 5 device to remain connected to the power pack for eight hours to ensure the battery receives a full charge.
• Li-Polymer and Li-Ion batteries are not affected by shallow charging. Furthermore, when the device has no external power source or battery the coin cell battery provides power to the security circuit.
• Disconnecting and unplugging the device power pack reduce the life of the coin cell battery, which does not recharge and must be replaced if drained.
• Conserve battery power by turning the Verifone Carbon Mobile 5 device off when not in use. Do not let the battery charge fall below 10% for extended periods of time as this may permanently diminish the battery capacity. Recharge the battery by attaching USB end of the power pack to the device and plugging the other end of the power pack into a wall outlet.
• The Verifone Carbon Mobile 5 device automatically shuts off when the battery reaches the critically low charge state.
• Please charge the device once a week even when the device is not in use.

Blank Display

When the device display is blank:

• If the device display appears dark, tap the screen using stylus. If the unit is in screen-saver mode, touch the screen to activate.
• If the display does shows incorrect or unreadable information, inspect all cable connections. In case the problem persists, reach out to your local Verifone representative for assistance.

Transactions Fail to Process

Multiple factors could be causing the unit to fail in processing transactions. Utilize the following steps to troubleshoot and identify the root of the failures.

Checking Magnetic Card Reader

To check the magnetic card reader:

1. Perform a transaction using one or more distinct magnetic stripe cards to rule out the possibility of a faulty card.
2. Ensure that you are swiping cards correctly.
3. Process a transaction manually using the keypad instead of the card reader. If the manual transaction is successful and the issue persists with the card reader, it may indicate a problem with the card reader itself.
4. If the problem persists, reach out to your local Verifone representative.

Checking Smart Card Reader

To check the smart card reader:

1. Execute a transaction using various smart cards to eliminate the possibility of a faulty card.
2. Verify that the card is inserted correctly.
3. Ensure the SAM cards are appropriately inserted into the designated slots and are securely in place (refer to Installing or Replacing SAM Cards).
4. If the issue persists, get in touch with your local Verifone representative.

Checking CTLS Reader

To check the CTLS reader:

Make sure there are no obstructions between the contactless logo and the card, ensuring a clear path between the contactless reader and the actual card for a seamless transaction.
