This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. 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 1720E sensor away from the device receiving the
interference.
4. Reposition the device receiving the interference.
5. Try combinations of the above.
