13.6 Guidance and
manufacturer ’s declaration –electromagnetic immunity
The EN-Motion is intended for use in the electromagnetic environment specified below. The customer or
the user of the EN-Motion should assure that it is used in such an environment.

Interference may occur in the

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 EN-Motion is
used exceeds the applicable RF compliance level above, the EN-Motion should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the EN-Motion.
b
Over the frequency range 15 kHz to 8 MHz, field strengths should be less than 3 V / m.
13.7 Recommended separation distances between portable and mobile RF
communications equipment and the EN-Motion
The EN-Motion is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.The
customer or the user of the EN-Motion can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the EN-Motion 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 metres (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
