The Wireless Professional is designed for use in an electromagnetic environment in which radiated
RF waves are controlled. The buyer or user of the Wireless Professional can contribute to preventing
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communication devices (transmitters) and the Wireless Professional according to the table of
recommendations below and according to the maximum output power of the telecommunication
device.

In the case of transmitters whose maximum output power is not shown in the table above, the
recommended spacing of d in metres (m) can be calculated using the appropriate equation for the
transmitter frequency, where P is the maximum output power of the transmitter in watts (W) as set by
the transmitter manufacturer
NOTE 1 At 80 MHz and at 800 MHz ,the spacing for 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.
Note
Mobile HF-Communication units may have influence to the Wireless Professional.
Please ensure that wire less communication devices, like WLAN, mobile phones, wireles telephones
and their station, Walki-Talkies keep a distance to the Wireless Professional of at least 3.3 m. (Based
upon the maximum output power of a regular mobile phone of 2 W).
