RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE ULTRA NOMADE
The Ultra Nomade is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Ultra Nomade can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the Ultra Nomade as recom-
mended 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 metres (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
NOTE 1 - At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
