Battery Features
The e280 device uses a single cell Li-ion battery. The internal logic of the battery
prevents both overcharging and undercharging (a fault condition in which the
battery level goes well below the minimum acceptable charge and the battery
becomes unusable).
The following are features of the battery:
•Single Li-ion cell.
•A safety circuit that:
•Prevents cell damage from overcharge, over-discharge, or overheating.
•Activates when the battery is left in an unused device for extended
periods.
•Charge the e280 device for eight hours before initial use.
•The e280 device comes with an extra battery that will power the security
circuit of the device in case, the device is tampered and the main battery fails
to charge. This extra battery has a life of 2 yrs.
•Ensure not to store the device for more than 1 week without charging, else
the secondary battery gets discharged in turn reducing the life of the battery.
Battery Behavior
(No Power Pack)
Manual Startup
Manual Shutdown
•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 e280 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 the USB-C end of the power pack to the device and plugging the
other end of the power pack into a wall outlet.
The device shifts to power pack mode and starts up automatically when the e280
is connected to a non-battery power source, regardless of the battery charge
state.
Hold the start button for about 10 seconds until the device displays the startup
screen.
Once the device is powered up, Verifone ADK MAC screen is displayed.
Hold the start button for about 10 seconds until the device is switched OFF.

Terminal Power
Pack
Connect the e280 device to the provided USB cable and insert the other end into
any USB charger head for initial charging.
Using an incorrectly rated power supply may damage the device or cause it not
to work as specified. Before troubleshooting, ensure that the power supply being
used to power the device matches the requirements specified on the bottom of
the device. (See
Specifications for detailed power supply specifications.) You can
use any standard USB charger.
Do not plug the power pack into an outdoor outlet or operate the device outdoors.
During a transaction, disconnecting the power by unplugging the device from a
wall power while at very low battery charge may cause transaction data files not
yet stored in the device memory to be lost.

attempts to reset the safety circuit when charging a battery that has been
discharged below this critical state.

readers.
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

Battery Does Not
Charge
The e280 battery must initially receive a full charge to ensure proper operation.
•Allow the e280 device to remain connected to the power pack for eight hours
to ensure the battery receives a full charge.
•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 e280 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 e280 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.

Transactions
Fail to Process
When the e280 device display screen does not show correct or clearly readable
information:
•Battery connection is not available to the user.
•If the display doesn't turn on, press and hold the power key for 8-10 seconds.
•Plug the charger.
•If the problem persists, contact your local Verifone service provider.
There are several reasons why the device may not be processing transactions.
Use the following steps to troubleshoot failures.
Check the Magnetic Card Reader
•Perform a test transaction using one or more different magnetic stripe cards to
ensure the problem is not a defective card.
•Ensure that you are swiping cards properly. With the e280 card reader, the
black magnetic stripe on the card should face down and outward (see Figure
6).
•Process a transaction manually. If the manual transaction works, the problem
may be a defective card reader.
