Recommended separation distances between
portable and mobile RF communications equipment and the Arm Blood Pressure Monitor.
The
Arm
Blood Pressure Monitor
i
s
intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the
Arm
Blood Pressure Monitor
can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the
Arm
Blood Pressure Monitor
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.
