Advice:
• Due to the digital safety encryption the operating range
may vary. If necessary, the module aerial can be installed
outside the building in order to achieve a larger operating
range. For this an extension kit, protection category IP 65,
is required (not part of the supply package).
• If traffic light control Control 300 is used (additional
equipment), a multi-channel hand transmitter together with a
multi-channel receiver is required.
