Guidance and manufacturer’s declaration - electromagnetic emissions

The Elite Series Warmer is intended for use in the electromagnet environment speciﬁ ed below. The customer or the end user of the Elite

Series Warmer 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 Elite Series Warmer, including cables, than the

recommended separation distance calculated from the equation applicable to

the frequency of the transmitter.

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 metres (m).

Field strengths from ﬁ xed RF transmitters, as determined by an

electromagnetic site survey,

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 absorption and reﬂ ection from

structures, objects and people.

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 Elite Series Warmer is used exceeds the applicable RF compliance level above, the Elite Series Warmer should be

observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or

relocating the Elite Series Warmer.

Over the frequency range 150 kHz to 80 MHz, ﬁ eld strengths should be less than [VI] V/m.

Guidance and manufacturer’s declaration – electromagnetic immunityRecommended separation

distance between portable and mobile RF communications equipment and the Elite Series

The Elite Series Warmer is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The

customer or the user of the Elite Series Warmer can help prevent electromagnetic interference by maintaining a minimum distance between

portable and mobile RF communications equipment (transmitters) and the Elite Series Warmer 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.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reﬂ ection from structures, objects and people.
