Guidance and manufacturer’s declaration – electromagnetic immunity
The PIEZON
®
BUILT-IN KIT is intended for use in the electromagnetic environment specied below. The customer or the user of the PIEZON
®
BUILT-IN KIT
should assure that it is used in such an environment.

including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = 0.35 √P
d = 0.35 √P 80 MHz to 800 MHz
d = 0.7 √P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufacturer
and d is the recommended separation distance in meters
(m).
Field strengths from xed RF transmitters, as determined
by an electromagnetic site survey,
a
should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE 1
NOTE 2
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reection from
structures, objects and people.
a
Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the
measured eld strength in the location in which the PIEZON
®
BUILT-IN KIT is used exceeds the applicable RF compliance
level above, the PIEZON
®
BUILT-IN KIT should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the PIEZON
®
BUILT-IN KIT.
b
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the PIEZON
®
BUILT-IN KIT
The PIEZON
®
BUILT-IN KIT is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the PIEZON
®
BUILT-IN KIT can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF commu-
nications equipment (transmitters) and the PIEZON
®
BUILT-IN KIT 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 reection
from structures, objects and people.
