NOTE:
When connecting an antenna, ensure that it does not exceed the permissible limits pre-
scribed by the national regulations for radio frequency devices.
4.2. Internal Antenna ANT4
Additionally the reader is equipped with an internal antenna (ANT4). The internal antenna supports
far field transponders as well as near field transponders. The internal antenna is located in the bot-
tom left corner of the housing and is marked with an antenna symbol. The maximum read range of
the antenna in combination with a far field transponder is approx. 40 cm. In combination with a
near field transponder the maximum read range is approx. 5 cm.
