3.3. Guidance and manufacturer's declaration on electromagnetic
immunity
The device is intended for use in the electromagnetic environment specified in the table below. The
customer or the user should assure that the device is used in the appropriate environment.
Electromagnetic Environmental Information
Conducted RF
IEC 61000-4-6
Portable and mobile RF Communication equipment
should be used no closer to any part of the device
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance:
80 MHz to 800 MHz
800 MHz to 2.5 GHz
Where P is the maximum
output power rating of the transmitter in watts (W)
according to the specifications supplied by the
Radiated RF
