Recommended separation distances between portable and
mobile RF communications equipment and the A&D unit
The model Wireless dynamic multi-parameter holter is intended for use in an
electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of The model Dynamic ECG recorder
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and The model Wireless dynamic multi-parameter holter 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.
