Setup help of the readers of the second generation

After turning on the reader (connection to the power supply) and the following startup phase,
the reader automatically changes to the "Setup" mode. The antenna (reader internal or
external) is also turned on.
In this status "search for transponders" the reader scans the antenna field for transponders
with all HF protocols (RF300, ISO 15693, ISO 14443). If a transponder is recognized in the
antenna field of the reader only the HF protocol of the recognized transponder type is used
and there is a change in the status to "Show quality". In this status you obtain direct
feedback of the communication with the transponder via the LED. If no transponder is
recognized for a longer period of time, the reader changes back to the "Search for
transponders" status.
When a "RESET" command is received, the reader changes back to the normal operation as
known from the RF300.
