Avoidance of Exposure to Electromagnetic Field
(EMF) Emissions
Extremely Low Frequency (ELF) Emissions
(50Hz (Europe) or 60Hz (US))
Notices:
a. Since Toshiba desktop PCs are 50Hz or 60Hz alternating current (AC)
devices, the power cord and power supply of this computer may emit
low levels of EMF energy in the ELF range.
The intensity level of those ELF emissions, however, even in close
proximity to the power supply and its AC power cord, is relatively
low in comparison to those of other common household appliances.
In addition, that intensity level rapidly falls off further with distance.
The minute levels of EMF energy in the ELF range that are emitted by
the power supply and its AC power cord pose no known health
hazards to human beings.
b. Toshiba CRT monitors use a cathode ray tube and require the
generation of a vertical sweep-frequency in the 50 to 110 Hz (ELF)
range. Consequently, the CRT monitor unit is an emitter of stray EMF
energy in the ELF range, as are all CRT monitors.
The intensity level of ELF energy are relatively low, however, in
comparison to those of other common household appliances, and
rapidly fall off further with distance.
The intensity levels of stray EMF energy in the ELF range that are
emitted by this CRT monitor pose no known health hazards to
human beings.
Very Low Frequency (VLF) Emissions (30,000Hz to 66,000Hz)
Notice: Toshiba CRT monitors use a cathode ray tube, and require the
generation of a horizontal sweep-frequency in the 30,000 to 66,000Hz (VLF)
range. Consequently, the CRT monitor unit is an emitter of stray EMF energy
in the VLF range, as are all CRT monitors.
The allowable levels of stray VLF 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)), to prevent interference with the
operation of other nearby electronic devices.
Toshiba CRT monitors have therefore been equipped with internal
shielding, to significantly reduce the stray emission of EMF energy in the
VLF range.
The minute levels of stray EMF energy in the VLF range that are in fact
being emitted by this CRT monitor unit fall off rapidly with distance and
pose no known health hazards to human beings.
