Table 21 Guidance and Manufacturer's Statement - Electromagnetic Immunity (cont’d)
The DrillSaw Mini 300 System is intended for use in the electromagnetic environment specified
below. The customer or the user of the DrillSaw Mini 300 System should ensure that it is used in
such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the Model
AR-300, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
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-300 is used exceeds the
applicable RF compliance level above, the Model AR-300 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-300
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
