1. Troubleshooting

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 the BP5 is used exceeds the applicable RF compliance level above, the BP5 should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the BP5.

b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Field strengths from fixed RF transmitters, as determined by

an electromagnetic site survey,

should be less than the

compliance level in each frequency range.

Interference may occur in the vicinity of equipment

marked with the following symbol:

For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING

Recommended separation distances between

portable and mobile RF communications equipment and the Wireless Blood Pressure Monitor

The Wireless Blood Pressure Monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are

controlled. The customer or the user of the Wireless Blood Pressure Monitor can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Wireless Blood

Pressure Monitor 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

determined 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.
