Recommended separation distances between
portable and mobile RF communications equipment and the model Grid Pad 10s
The Grid Pad 10s is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Grid Pad 10s can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Grid Pad 10s as recommended below,
according to the maximum output power of the communications equipment.

Separation distance according to frequency of transmitter m
150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.7 GHz
0.01 0.12 0.04 0.07
0.1 0.37 0.12 0.23
1 1.17 0.35 0.7
10 3.7 1.11 2.22
100 11.7 3.5 7.0
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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
