SE-601 Series Electrocardiograph User Manual EMC Information
- 76 -
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 SE-601 series
electrocardiograph
is used exceeds the applicable RF compliance level above, SE-601 series
electrocardiograph
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating SE-601
series electrocardiograph.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
c
The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765
MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz
to 40.70 MHz. The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0
MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz,
14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99
MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
