Product Manual

Guidance and manufacturer’s declaration –electromagnetic immunity
If the measured field strength in the location in which the ProBP™ 2000 Digital Blood Pressure Device is used exceeds the
applicable RF compliance level above, the ProBP™ 2000 Digital Blood Pressure Device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the ProBP™ 2000 Digital Blood Pressure Device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment
and the ProBP™ 2000 Digital Blood Pressure Device
The ProBP™ 2000 Digital Blood Pressure Device is intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the ProBP™ 2000 Digital Blood Pressure Device can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the device 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 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.
