CHARGING THE READER BATTERY
As mentioned above (LED Indicator), the Flash reader may indicate low battery at power up by
showing red for two seconds then turn solid green. The first time this happens, there will
probably be sufficient battery available for several more card swipes, but the battery should be
charged soon. If the low battery warning is ignored and the battery gets too low, the reader will
refuse to power up until it has been charged.
Charge the reader by connecting it to any USB port on a running system or a compatible 5VDC
source. For best results, allow the battery to charge fully (until the LED goes to steady amber)
before using the reader again.
