OPERATION MANUAL
Recommended values for separation distance between portable and mobile radio frequency
communication means and the device
The device is intended for use in an electromagne c environment in which the levels of radiated interference are
monitored. The purchaser or the user of the device can avoid the e
ff
ects of electromagne c interference providing a
minimum separa on distance between portable and mobile radio frequency communica on devices (transmi ers)
and the device, as recommended below, taking into account the maximum output power of transmission equipment
Nominal maximum

Notes:
A greater value of the
fi
eld density is applied at frequencies of 80 and 800 MHz.
The reduced expressions are applicable in all the cases. The propaga on of electromagne c waves is a

by absorp on or re
fl
ec on from structures, objects and people.
At determining recommended values of separa on distance d for transmi ers with nominal maximum power
output, which is not men oned in the table, the nominal maximum output power P in Wa s speci
fi
ed in the
transmi er manufacturer’s documenta on is subs tuted into reduced expressions.
