Power frequency magnetic fields should be at levels characteristic of typical location in a typical hospital
environment.
Portable and mobile RF communications equipment should be used no closer to any part of the ME Equipment,
including cables, than the recommended separation distance calculated from 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 and d is the recommended separation distance in meters (m).

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.
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 ME Equipment is used exceeds the applicable RF compliance level above, the ME Equipment should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the ME Equipment.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Recommended Separation Distances
RECOMMENDED SEPARATION DISTANCE BETWEEN PORTABLE AND MOBILE RF COMMUNICATION EQUIPMENT AND THE ME EQUIPMENT
The ME Equipment is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the ME Equipment can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the ME Equipment as recommended below, according to the maximum output power of the
communication 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 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.
