KERN & SOHN MCB 300K100M - Manual (Page 14)

Recommended separation distance between
portable and mobile RF communications equipment and the MCB 300K100M, MPT 300K100M
The MCB 300K100M, MPT 300K100M is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the MCB 300K100M, MPT 300K100M can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the MCB 300K100M, MPT 300K100M 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 propagation is affected by absorption
and reflection from structures, objects and people.
