Guidance and manufacturer's declaration – electromagnetic immunity
The model ECG600G Electrocardiograph(ECG) is intended for use in the electromagnetic
environment
specified
Electrocardiograph(ECG) should assure that it is used in such an environment.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is affected by absorption
and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
a
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 model ECG600G Electrocardiograph(ECG) is used exceeds the
applicable RF compliance level above, the model ECG600G Electrocardiograph(ECG) should be
observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the model ECG600G Electrocardiograph(ECG).
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
