up to a maximum range of 30 metres. Occasionally house construction and materials can reduce this
communication range and it is advisable, where possible, to try and avoid directing communication through
metal frames or solid concrete walls
A. Mounted 1 m above the floor.
1 m
B. Not above radiator/heat source. C. Not in direct sunlight.
