Maintaining a safe work environment
As a result, all desk-top and external hard drives are required to comply with the US Federal
Communications Commission (FCC) Standards digital devices, the Canadian Interference-
Causing Equipment Regulations and the European Community Standards.
(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 hard 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.
Freecom external hard drives have therefore been equipped with internal shielding, to
significantly reduce the stray emission of RF energy.
Nevertheless, airlines may prohibit the use of all external hard drives (and any other portable
electronic devices that could emit stray RF energy) during takeoffs and landings, because
of possible interference with the reception of signals by airborne electronic navigation
devices.
c. FCC regulations, ICES, and European Standards digital devices severely limit the levels of
RF energy that may be emitted by a external hard drive.
The resulting emissions therefore also fall well within the allowable limits that have been adopted
by OSHA in 29 CFR 1910.97, and that have been adopted by the promulgators of all other know
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 Freecom
external hard drives comply with all existing regulations and standards, and pose no known
health hazards to human beings.
