RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE
RF COMMUNICATION DEVICE AND THE SYSTEM
Consona N6 series is intended for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of system can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communication
equipment (transmitters) and system as recommended below, according to the maximum output
power of the communication equipment.

For transmitters at a maximum output power not listed above, the recommended separation
distanced in meters (m) can be determined 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.
If system image distortion occurs, it may be necessary to position system further from sources of
conducted RF noise or to install external power source filter to minimize RF noise to an acceptable
level.
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.
