MAINTENANCE INFORMATION
Replacement Units
If any part of the beam detector set needs to be
replaced for reasons of damage or malfunction, the
transmitter, receiver and interface can all be ordered
separately.
As a result of product enhancements, however, some
older issues of interface or receiver are not compatible
with new units and it is not possible to replace older
versions with the enhanced version separately. In such
cases, both interface and receiver must be replaced if
a new receiver is to be installed.
The transmitter is not affected.
