Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM -
for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
portable and mobile RF communications equipment and the ECG-1101 Series ECG
The model ECG600G 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
ECG600G Electrocardiograph(ECG) can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and
the model ECG600G 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.
