Recommended separation distance between
portable and mobile RF communications equipment and the KNEESUP Smart Core
The KNEESUP Smart Core is intended for use in an electromagnetic environment (for home healthcare) in which radiated RF
disturbances are controlled. The customer or the user of the KNEESUP Smart Core can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
KNEESUP Smart Core 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 meters (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 propagation is affected by absorption and reflection from
structures, objects and people.
