Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
Portable and mobile RF communications
equipment should be used no closer to any
part of the diode laser Medical system,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter. Recommended separation
distance
where
P
is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey,
a
should be less than the compliance
level in each frequency range.
b
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the diode laser Medical
system is used exceeds the applicable RF compliance level above, the diode laser Medical
system should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the diode laser
Medical system.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
