WARNING
Ifthisunitistobeconnectedtoanon-power
limited 24 volt dc supply, the National Electrical
Code (NFPA70) requires that those leads be
separated from other classes of wiring connected
to this unit.
CAUTION
Crosstalk,interference,orhumcanbeinduced
in signal lines, causing poor audio output or
confusing messages, which interferes with the
capabilityofthisequipment.Donotinstallpower
lines in the same conduit as signal lines.

AR2000-P and AR2000-Z.
WARNING
It is important that the communication lines
be properly connected to their respective
communication port. Failure to connect the
cables properly will damage the devices and
possibly render them inoperable.
