CAUTION:
-
Check to ensure that the wiring is correct.

DO NOT run all the transmission cable for
the central station along the power line
and other transmission cables, or
malfunction may occur due to the noise,
etc. If the transmission cable for the
central station is required to be run along
the power line and other transmission
cables, separate the cable more than
15cm away from other cables, or run the
