Recommended separation distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,7 GHz
Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in metres (m).
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
Recommended separation distance between
portable and mobile RF communications equipment and the Receiver(HR321),
Receiver(HR320)
The Receiver(HR321), Receiver(HR320) is intended for use in an electromagnetic environment (for
home healthcare) in which radiated RF disturbances are controlled. The customer or the user of the
Receiver(HR321), Receiver(HR320) can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and
the Receiver(HR321), Receiver(HR320) as recommended below, according to the maximum output
power of the communications equipment.
