Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The
Battery Charger
is intended for use in the electromagnetic environment specified below. The customer or the
user of the
Battery Charger
should assure that it is used in such an environment.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

a)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured filed strengths in the location in which the
Battery Charger
is used exceeds the
applicable RF compliance level above, the
Battery Charger
should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1V/m.
