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.

■

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).
