Note: Use this command only for tuning the base antenna and not for tuning the complementary
antenna.
The output power is set to about 4 watt without any readjust. If the Reader is in the buffered read mode
it will be switched off and communication with Transponders is no longer possible. The status [0x82]
“Command not available” appears.
The antenna tuning mode is indicated by a flashing of the LED 5 with 2Hz. If an error occurred (e.g.
max. current, voltage to high or temp alarm) the LED flashes with a frequency of 8Hz. To leave the
base antenna tuning state a
5.3. [0x63] CPU Reset
has to be performed by the host.
