This allowance is typically enough for a frame wall with non-
metallic siding; however certain materials can reduce range
even further. Metal siding, stucco, and some types of glass
can reduce signal range by as much as ¾ or more, compared
to the ½ reduction typical of most obstructions. It is possible to
receive a signal through these materials, however maximum
range will be much less due to their tendency to absorb or
reflect a much larger portion of the sensor’s signal.
Note:
When opening the battery cover make sure that the batteries do
not spring free from the contacts since this will cause start and
transmission problems.
Battery Change:
It is recommended to replace the batteries in the unit
approximately every 3 years to ensure optimum accuracy.
