IMMUNITY TEST
IEC 60601 TEST LEVEL
3 Vrms
Conducted RF
150kHz to 80MHz
IEC 61000-4-6
3V/m
Radiated RF
80MHz to 2.5GHz
Field strengths from transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, A M and F M 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 filed strength in the location in which the
TheraFace PRO is used exceeds the applicable RF compliance level above. The TheraFace PRO should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary,such as reorienting or relocating the higi Station.Overthe frequency range 150kHz to 80 MHz, filed strengths should be less than 3V/m.
COMPLIANCE LEVEL
3V
Portable and mobile RF communications equipment should be used no closer to any part of the
higi Station, including cables, than the recommended separation distance calculated from the
equation application 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).b
Field strengths form fixed RF transmitters, as determined by an electromagnetic site survey, a
should be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1At 80 MHz and 8 0 0 MHz, the higher frequency range applies.
3V/m
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is affected by absorption
and reflection from structures,objects and people.
