Avoidance Of Exposure To Emf Emissions - Toshiba PA3454U-1DV2 - External USB 2.0 DVD Super Multi Drive User Manual

B. AVOIDANCE OF EXPOSURE TO EMF
EMISSIONS
Radio Frequency (RF) Emissions
Maintaining a Safe Work Environment
(a) External DVD SuperMulti Drives generate digital
timing pulses at frequencies within the RF range,
and consequently may emit minute levels of stray
EMF emissions in the RF range.
As a result, all desk-top and External DVD
SuperMulti Drives are required to comply with the
US Federal Communications Commission (FCC)
Standards for "Class B" digital devices, the
Canadian Interference-Causing Equipment
Regulations and the European Community
Standards.
("Class B" digital devices are authorized for use in
residential environments and are not permitted to
intentionally emit RF energy. Nevertheless, they
are permitted to unintentionally emit low levels of
RF energy, as a result of the generation of digital
timing pulses by their clock oscillator circuits).
(b) The allowable levels of RF energy that may be
emitted by External DVD SuperMulti Drives are
severely limited in their intensity by the existing
FCC Regulations (47 CFR Section 15.109 (a)),
Canadian ICE Regulations and European
Community Standard N55022, to prevent
interference with reception on nearby radio and
T.V. receivers.
External DVD SuperMulti Drives have therefore
been equipped with internal shielding, to
significantly reduce the stray emission of RF
energy.
