Electromagnetic Interference (EMI)

To reduce electromagnetic interference emissions (possible interference problems with handheld telephones), check the date of manufacture of the CPU (517A27) units. If they were manufactured before April, 1993, replace them with a later version.

!CAUTION:

■For the control unit, do not use an AC outlet that is controlled by a wall switch or some other switch.

■Use an approved ground (AC receptacle for 3-prong plug).

■Do not install the control unit outdoors.

■Do not place the control unit near extreme heat (furnaces, heaters, attics, or direct sunlight).

■Do not expose the control unit to devices that generate electrical interference (such as arc welders or motors).
