Battery Does
not Charge
The Verifone Carbon Mobile 5 battery must initially receive a full charge to
ensure proper operation.
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.
• 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.
