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 EQUIPMENT is used exceeds the applicable RF compliance level above, the
EQUIPMENT should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the EQUIPMENT.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
* Exceptions from Standard IEC 60601-2-4 Section 202 were applied.
Recommended separation distances between
portable and mobile RF communications equipment and the EQUIPMENT
The EQUIPMENT is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the EQUIPMENT can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the EQUIPMENT 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.
