the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from the 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:
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 IQecg
®
is used exceeds the applicable RF Compliance level above, the IQecg
®
should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orientating or relocating the IQecg
®
.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
IQecg
®
The IQecg
®
is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the IQecg
®
can help prevent electromagnetic interferences by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the IQecg
®
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 power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz to 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
structures, objects and people.
