Recommended separation distances between portable and mobile RF
communications equipment and the EQUIPMENT or SYSTEM
portable and mobile RF communications equipment and the 12-channel Electrocardiograph
The 12-channel electrocardiograph is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the 12-channel
electrocardiograph can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the 12-
channel electrocardiograph 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 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 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.
