Guidance and manufacturer’s declaration – electromagneticemissions
The model 675is intended for use in the electromagnetic environment specified below. The customer or the user of the model 675should assure that it is used in such
anenvironment.
Emissions test Compliance Electromagnetic environment -guidance
RF emissions, CISPR 11 Group 1 The model 675uses RF energy only for its internal function. Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronicequipment.
RF emissions, CISPR 11 Class B The model 675is suitable for use in all establishments, including domestic establishments and those directly
connected to the public low-voltage power supply network that supplies buildings used for domesticpurposes.

Guidance and manufacturer’s declaration – electromagneticimmunity
The model 675is intended for use in the electromagnetic environment specified below. The customer or the user of the model 675should assure that it is used in such
anenvironment.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects andpeople.

Portable and mobile RF communications equipment should be used no closer to any part of the model 675, including cables,
than the recommended separation distance calculated from 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 and d is
the recommended separation distance in meters(m).
At 80MHz and 800MHz, the higher frequency rangeapplies.
Field strengths from fixed 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:
Notes
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 model 675is used exceeds the applicable RF compliance level above, the model
675should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
model675.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
