58 VX 680 INSTALLATION GUIDE
Smart Battery
Does Not Charge
The VX 680 smart battery must initially receive a full charge to ensure proper
operation.
Spare Battery in
Base Station
Does Not Charge
When the spare battery is installed in the base for charging, the Base LED will
flash amber if the battery is charging, or stay solid green if the battery is fully
charged. If the battery is not charged and the LED does not flash amber, check
the contacts on the battery and in the terminal base to make sure they are clean.
Also, try charging a known good battery to see if the problem is with the base or
with the battery. If the problem persists, contact your local VeriFone
representative.
Blank Display
When the VX 680 terminal display screen does not show correct or clearly
readable information:
• The battery pack may not be connected properly. Remove and reinstall the
battery pack.
• Check terminal power connection.
• Remove and reapply power to the terminal.
• If the problem persists, contact your local VeriFone service provider.
• Allow the VX 680 terminal to remain connected to the power pack for 6 hours
to ensure the battery receives a full charge.
• Li-ion batteries are not affected by shallow charging. Furthermore, when the
terminal has no external power source or battery the coin cell battery provides
power to the security circuit.
• Uninstalling the battery and unplugging the terminal 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 VX 680 terminal off when not in use. If
the terminal will not be used for an extended period of time, keep the Li-ion
battery inserted in the terminal, and power up the terminal periodically to
check the battery charge. 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 power cable to the terminal
and plugging the power pack into a wall outlet.
• The VX 680 terminal automatically shuts off when the smart battery reaches
the critically low charge state. If this occurs, the smart battery must recharge
a minimum of 1/2 hour before it can power the terminal. It may take several
recharge attempts to reset the safety circuit when charging a smart battery
that has been discharged below this critical state.
