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.

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.
