Route the wiring around the inside perimeter of the cabinet. It should not cross the
circuit board where it could induce noise into the sensitive microelectronics or pick
up unwanted RF noise from the high speed circuits. See Figure 3-1 for an
example.
High frequency noise, such as that produced by the inductive reactance of a speaker
or bell, can also be reduced by running the wire through ferrite shield beads or by
wrapping it around a ferrite toroid.

Note: All circuits are power limited except the battery and AC cabling. Maintain 1/4 inch spacing be-
tween high and low voltage circuits and between power-limited and non-power limited circuits.
