Recommended separation distances between portable and mobile RF communications equipment
and the [IH 25/2]
The [IH 25/2] is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of the [IH 25/2] can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the [IH
25/2] 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 affected by absorp-
tion and reflection from structures, objects and people.
