Table 199 Guidance and Manufacturer's Statement - Electromagnetic Immunity (cont’d)
The Universal DrillSaw Battery Charger is intended for use in the electromagnetic environment
specified below. The customer or the user of the Universal DrillSaw Battery Charger should
ensure that it is used in such an environment.

should be used no closer to any part of the Model
AR-400UBC, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the

Field strengths from fixed RF transmitters, as

a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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.
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 and TV 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 field strength in the location in which the Model AR-400UBC is used exceeds
the applicable RF compliance level above, the Model AR-400UBC should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Model AR-400UBC
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
