The installation of an X10-based system in an apartment unit is complete. The apartment
complex uses shared services to supply each unitwith electric power, natural gas, and water. To
protect the equipment, all A/V components and computers are connectedto the A/C wiring by
using surge suppressors. The client calls and states that someof the devices are operating
erratically and spontaneously from any of the X10 controllers. The equipment is operating
manually and other devices are operating normally. To remedy this problem, the technician
should.
