Recommended distance of separation from portable telephone, etc.
The following shows the recommended distance of separation of the
equipment from portable or mobile RF communication devices.
Recommended distance of separation of equipment from portable or mobile RF communication
devices
The equipment is intended to be used in the electromagnetic environment where the RF interference is
regulated. Client or user of the equipment can suppress the electromagnetic interference by controlling
the minimum distance between portable or mobile RF communication device (transmitter) and this
equipment as recommended below based on the maximum output of the sending device.

In case of maximum rated power output not listed above, recommended distance of separation d in terms of
meters (m) can be determined by an equation corresponding to the transmitter frequency. In the equation,
P is the maximum rated power output in Watts (W) of transmitter.
Note 1. In case of 80MHz and 800MHz, apply a high frequency range.
Note 2. The guideline does not apply to all circumstances. The electromagnetic diffusion is affected by
reflection and absorption by structure, thing and person.
