frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at the user’s own expense. The following techniques
of reducing the interference problems are applied easily.
1. Disconnect the equipment from it’s power source to verify that it is or is not the
source of the interference.
