Electrical Information
The appliance is intended for use in the electromagnetic environment specifi ed below . The customer or the end user
of this appliance should assure that it is used in such an environment .

Portable and mobile RF communications equipment should
be used no closer to any part of the appliance, including
cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter .
Recommended separation distance
d = [3 .5/3] √P
d = [3 .5/3] √P 80 MHz to 800 MHz
d = [7/3] √P 800 MHz to 2 .5 GHz
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 fi 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. At 80 MHz and 800 MHz, the higher frequency range applies. 2. These guidelines may not apply in all situations.
Electromagnetic propagation is aff ected by absorption and reflection from structures, objects and people.
a. Field strengths from fi 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
fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured fi eld strength in the location in which the appliance is
used exceeds the applicable RF compliance level above, the appliance should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the appliance.
b. Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than [VI] V/m.
The appliance is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled . The customer or the user of the appliance can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the appliance 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 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. 2. These guidelines may not apply
in all situations. Electromagnetic propagation is aff ected by absorption and reflection from structures, objects and people.
