Guidance and manufacturer’s declaration – electromagnetic immunity
The UP-DF550 is intended for use in the electromagnetic environment specified below. The customer or the user of
the UP-DF550 should assure that it is used in such an environment.
Immunity test
IEC 60601

Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the UP-DF550,
including cables, than the recommended separation
distance calculated from the equation appliance 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 and d is the recommended separation
distance in meters (m).

Interference may occur in the vicinity of equipment
marked with following symbol:
IEC 61000-4-3 80 MHz to 2.7 GHz
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
