The customer or the user of the digital Blood Pressure Monitor type BW-BT1 can help
prevent electromagnetic interference by maintaining a minimum distance between port-
able and mobile RF communications equipment (transmitters) and the Digital Blood Pres-
sure Monitor type BW-BT1 as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rates 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 transmit-
ter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800MHz, the reparation 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.
