Tips for arranging the antenna:
• Locate the antenna as far from metal elements as possible (con-
necting wires, bracket rings, etc.) in order to prevent interferences,
• Metal surfaces in the direct vicinity of the antenna (e.g. flush
mounted metal boxes, metal door frames) may impair signal
reception!
•
Do not
cut or shorten the antenna - its length is perfectly matched
to the band in which the system operates.
• Make sure no part of the antenna sticks out of the wall switch box.
