Interference may occur in the vicinity of equipment marked with the following symbol:

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.

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 Digital Blood Pressure

Monitor is used exceeds the applicable RF compliance level above, the Digital Blood

Pressure Monitor should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the

Digital Blood Pressure Monitor.

Recommended separation distances between portable and mobile RF communications equipment and the Digital Blood Pressure Monitor.

Pressure Monitor is intended for use in an electromagnetic environment in which radiated

RF disturbances are controlled. The customer or the user of the Digital Blood Pressure

Monitor can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Digital

Blood Pressure Monitor as recommended below, according to the maximum output power of the communications equipment.
