ECG1200G Electrocardiograph - User Manual
40
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.
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 model ECG1200G Electrocardiograph(ECG) is used
exceeds
the
applicable
RF
compliance
level
above,
the
model
ECG1200G
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 ECG1200G Electrocardiograph(ECG).
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM -

Recommended separation distances between
portable and mobile RF communications equipment and the ECG-1101 Series ECG
The model ECG1200G Electrocardiograph(ECG) is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the
model ECG1200G Electrocardiograph(ECG) can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the model ECG1200G Electrocardiograph(ECG) as recommended below,
according to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above the recommended separation
distance d in metres (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
