3.5.5
Antenna Distance - Metal Bodies
Influence of the magnetic field in the vicinity of the antenna by a metal body results in shorter reading
distances and can even cause failure of reading functionality. The electro-magnetic field is short-
circuited in the metallic environment.
WARNING
To maximize the antenna when mounting, we recommend surface cable mounting with a spacer
frame
The read/write quality of the antenna should be checked in all cases
Often an air gap in the conductive body is sufficient to weaken the magnetic sufficiently so that the
antenna is no longer materially influenced

Display and Signal Elements
The registration units are equipped with a two-color, red/green illuminating symbol and a buzzer.
The buzzers provide acoustic signaling of the access decision
The red/green illuminating symbol indicates the operating state and access decision
The keypad lights up brightly when a PIN code input is required
The detailed signaling of all registration units during the different booking processes is described in
the documentation
