Table 206. Recommended separation distances between portable and mobile RF communications equipment and WSK-1011
WSK-1011 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
WSK-1011 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and WSK-1011 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.
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 aff ected by absorption and refl ection
from structures, objects and people.
