Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The EasyOne is intended for use in the electromagnetic environment specified below. It is the responsibility of the customer or user to
assure that the EasyOne is used in such an environment.
Immunity Test EN 60601 Test Level
Conducted RF 3 V rms
EN 61000-4-6 150 KHz to 80 MHz
Radiated RF 3 V/m
EN 61000-4-3 80 MHz to 2.5 GHz
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 radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment 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 re-orienting or re-
locating the equipment.
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances
The table below provides the recommended separation distances (in meters) between portable and mobile RF communication equip-
ment and the EasyOne. The EasyOne is intended for use in the electromagnetic environment on which radiated RF disturbances are
controlled. The customer or the user of the EasyOne can help prevent electromagnetic interference by maintaining a minimum dis-
tance between portable and mo-bile RF communications equipment (transmitters) and the EasyOne as recommended below, accord-
ing 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all instances. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people

Electromagnetic Environment – Guidance
Portable and mobile RF communications equipment
should be used no 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.
