1.1 Safety messages
WARNING
Failure to follow safe installation and servicing guidelines could result in
death or serious injury.
Ensure the transmitter is installed by qualified personnel and in accordance
with applicable code of practice.

WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.
