NOTE 1 At 80 MHz and 800 MHz, 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.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
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 BP7S is used exceeds the applicable RF compliance level above, BP7S should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating BP7S.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

portable and mobile RF communications equipment and the Wireless Blood Pressure Wrist Monitor
BP7S is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user of BP7S can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and BP7S as recommended below, according to the maximum output power of the communication equipment.
