LEDs 1, 3, and 4 are turned ON for approximately four seconds after the hardware initialization has completed, then the application code is initialized. The amount of time the application takes to initialize depends on the size of the database, about 3 seconds without a card database. Each 10,000 cards will add about 3 seconds to the application initialization. When LEDs 1, 2, 3 and 4 flash at the same time, data is being read from or written to flash memory, do not cycle power when in this state. If the sequence stops or repeats, perform the Bulk Erase Configuration Memory procedure. If clearing the memory does not correct the initialization problem, contact technical support.
