Electromagnetic Compatibility: Electromagnetic Compatibility (EMC)
Guidance and Manufacturer's Declaration - Electromagnetic
Immunity
The MAC 3500 is intended for use in the electromagnetic environment specified
below. It is the responsibility of the customer or user to assure that the MAC3500 is
used in such an environment.
Immunity Test EN 60601 Test Level Compliance Level Electromagnetic Environment – Guidance
Portable and mobile RF communications equipment sho
uld not
be used closer to any part of the 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).
Field strengths from fixed RF transmitters, as determined by

, should be less than the compliance
level in each frequency range

.
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 reflection from structures,
objects, and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile 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.
