When mounting the read/write head, make sure there are no metallic substances
within 10 mm of the head. Metal in the vicinity of the SLK's antenna would greatly
reduce the potential transmission distance between the SLK and the MDT or prevent
the transmission of data altogether.

3.3 Antenna orientation

The read/write head contains a ferrite antenna under the dark, semi-transparent cap
on the mounting frame of the SLK. The antenna generates the electromagnetic HF
field for exchanging data with the MDT.
For data transmission without interruption, the antenna and the MDT must be within
a certain distance from one another (see Fig. 9).
The antenna comes mounted such that the SLK can communicate with the MDT
on the workpiece pallet given standard installation on the section profile of Bosch
transfer systems.
To adjust to special mounting situations, the antenna can be carefully removed and
replaced 90° vertically by removing the cap. This could be necessary if the MDT is
mounted on the underside of a workpiece pallet and the SLK needs to be mounted
in a space-saving vertical position.
