Instruments which bear the Underwriters Laboratories, Inc.
label should be interconnected with accessories that have the
proper electrical compatibility and are listed as meeting the
requirements of the UL Medical and Dental Equipment
Standard. Connection of accessories not meeting these
requirements may result in electrical leakage currents in
excess of those allowed by the standard and present a potential
electrical shock hazard to the person being tested.
Any program aimed at obtaining reliable measurements
of otoacoustic emissions should be staffed and supervised
by appropriately-trained individuals.
