RECOMMENDATIONS AND DECLARATION BY THE MANUFACTURER
CONCERNING ELECTROMAGNETIC IMMUNITY
Wireless Professional is designed for use in the electromagnetic environment stipulated below. The
buyer or user of the Wireless Professional must ensure it is used in this recommended environment.

Portable and mobile RF communication devices must
only be used relative to the Wireless Professional and its
wiring at a distance which is not less than the spacing
recommended and calculated using the appropriate
equation for the transmitter’s frequency.
Recommended spacing
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
where P is the maximum output power of the transmitter
in watts (W) set by the manufacturer’s specifications and
where d is the recommended spacing in metres (m).
The field intensity of RF fixed transmitters, as determined
by an electromagnetic survey a must be less than the
observance level to be found in each frequency range.
Interference may occur close to any appliance identified
by the following symbol:
NOTE 1 At 80 MHz and at 800 MHz ,the high frequency amplitude is applied
NOTE 2 These guidelines may not be appropriate for some situations. Electromagnetic wave
propagation is modified by absorption and reflection due to buildings, objects and persons.
a The field intensity from fixed transmitters, such as radio telephone base stations (cellular/
wireless) and a mobile radio, amateur radios, AM and FM radio transmissions and TV transmissions
cannot be predicted with any accuracy. It may therefore be necessary to consider an analysis of the
electromagnetic environment of the site to calculate the electromagnetic environment coming from
fixed RF transmitters. If the field intensity measured in the environment where the Wireless Professional
is located exceeds the appropriate RF observance level above, the Wireless Professional should be
monitored to ensure it is operating properly. In the event of abnormal operation, new measures may
then be imposed, such as realignment or movement of the Wireless Professional.
b Above the frequency amplitude from 150 kHz to 80 MHz, the field intensity must be < 3 V/m.
