Radio Frequency (RF) Emissions

Notice: All personal computers generate digital timing pulses at
frequencies within the RF range, and consequently may emit minute
levels of stray EMF energy in the RF range.

As a result, all desktop PCs have been certified by the US Federal
Communications Commission (FCC), by Industry Canada Requirements
(ICES: Interference-Causing Equipment Standards) and by European
Regulations and Standards (VDE, et al.) as being “Class B” digital devices.
(“Class B” digital devices are authorised 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.)

The allowable levels of RF energy that may be emitted by Toshiba
desktop PCs are severely limited in their intensity by existing FCC
Regulations, (47 CFR Section 15.109(a)), and by ICES and European
Standards (EN55022) to prevent interference with reception on nearby
radio and T.V. receivers.

Toshiba desktop PCs have therefore been equipped with internal
shielding, to significantly reduce stray emissions of RF energy.

Because FCC Regulations and ICES and European Standards for “Class B”
digital devices severely limit the levels of RF energy that may be emitted
by a Toshiba desktop PC, the resulting emissions also fall well within the
allowable limits that have been adopted by OSHA in 29 CFR Section
1910.97, and that have been adopted by the promulgators of all other
known regulations and standards that relate to the emission of EMF
energy in the RF range.

Consequently, the minute levels of EMF energy in the RF range that are
emitted by Toshiba desktop PCs comply with all existing regulations and
standards, and pose no known health hazards to human beings.
