These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio 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 his own
expense. The following techniques of reducing the interference
problems are applied easily.
1. Disconnect the Controller from its power source to verify that it
is or is not the source of the interference.
2. If the Controller is connected into the same outlet as the device
with which it is interfering, try another outlet.
3. Move the Controller and SS7 sc sensor away from the device
receiving the interference.
4. Reposition the device receiving the interference.
5. Try combinations of the above.
