5 Installation
5.1 General installation instructions
When mounting several read/write heads adhere to the minimum distances
between the systems�
Flush mounting of a read/write head in metal reduces the read/write
distance�
The immediate vicinity of powerful HF emission sources such as welding
transformers or converters can affect operation of the read/write heads�
Information on the available mounting accessories is available on our website at:

5.2 Notes on ID tag mounting
If the ID tags are mounted in/on metal, the read/write distance is reduced�
For positioning the ID tags the read/write heads are marked with an
antenna symbol on the active face� It designates the middle of the
integrated antenna coil and has to correspond with the middle of the ID tag�
The orientation of the read/write head antenna axis must correspond with
the axis of the ID tag coil�
