Battery Behavior
(No Power
Cable)
When provided with external power, the VX 600 device charges its internal battery
to 90%. No transactions are allowed while the VX 600 charges its battery, but the
iPhone can be operated on its own battery power. When the VX 600 battery
reaches 90% charge, the VX 600 provides pass-through power to the installed
iPhone, and transactions can be executed using the iPhone and VX 600. At any
time, you can override these defaults and enable pass-through power to the
iPhone by pressing the Enter+3 key combination, but this causes the VX 600 to
enter Sleep Mode.
When operating on battery alone, the VX 600 device cable allows for pass-
through power to the iPhone as long as the VX 600 battery exceeds 80% charge.
NOTE
•
The VX 600 device operates on battery power or AC power. The battery
charger in the device is active whenever the power pack is connected. Both
the batteries in the device as well as in the iPhone are charged by PC power
or the external power pack.
• Lithium-ion polymer batteries are not affected by shallow charging. When the
device has no external power source or smart battery, the coin cell battery
procides power to the security circuit.
• When the VX 600 device is in Hibernation Mode or whenever the iPhone
enters its own Hibernation Mode, all pass-through power is disabled.
