Note: 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 with the equipment is operated in its installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed and used in
accordance with the product manual, may cause harmful interference to radio communications. If
this equipment does cause harmful interference, the user will be required to correct the
interference.
Due to the phenomena being observed and the material properties being measured, this
equipment does radiate radio frequency energy while in the active test mode. Care should be taken
to insure this radio frequency energy causes no harm to individuals or other nearby equipment.
