Recommended separation distances between portable and mobile RF communications
equipment and the ECG80A Electrocardiograph (ECG)
The ECG80A Electrocardiograph (ECG) is intended for use in the electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the ECG80A
Electrocardiograph (ECG) can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters)
and the ECG80A 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
distanced in meters (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 l At 80MHz and 800MHz, 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.
