Recommended separation distances between portable and mobile RF communi-
cations equipment and the device
The device is intended for use in an electromagnetic environment in which
radiated therefore disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (trans-
mitters) and the device as recommended 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 transmitter
manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propaga-
tion is affected by absorption and reflection from structures, objects and people.
