GUIDANCE AND MANUFACTURER'S DECLARATION
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless)
telephones and land mobile radio, AM and FM radio broadcast, and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the OMRON BP710CANN is used exceeds the applicable RF
compliance level above, the OMRON BP710CANN should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the OMRON BP710CANN.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance between portable and mobile RF communications
OMRON BP710CANN is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of this OMRON BP710CANN can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the OMRON BP710CANN 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.
