Recommended separation distances between portable and mobile RF
communications equipment and the TONO-PEN
The TONO-PEN VET is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the TONO-PEN VET can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the TONO-PEN VET 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.
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 absorption
and reection from structures, objects and people.
