9. GUIDANCE AND MANUFACTURER’S DECLARATION
Recommended separation distance between portable and mobile RF communications
equipment
and the OMRON BP742CANN including AC-adapter
OMRON BP742CANN including AC-adapter is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of this OMRON
BP742CANN including AC-adapter can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the
OMRON BP742CANN including AC-adapter 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
