SAFETY PRECAUTIONS
Guidance or Manufacturer’s declaration - electromagnetic immunity
The Model BD-X201MS is intended for use in the electromagnetic environment specified below.
The customer or the user of the Model BD-X201MS should assure that it is used in such an environment.
Immunity Test

Electromagnetic environment - guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of
the Model BD-X201MS, including cables than
the recommended separation distance calcu-
lated from the equation applicable to the fre-
quency 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 recom-
mended separation distance in meters (m).
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 equip-
ment 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 mea-
sured field strength in the location in which the Model BD-X201MS is used exceeds the applicable RF compliance level above,
the Model BD-X201MS should be observed to verify normal operation. If abnormal performance is observed, additional mea-
sures may be necessary, such as re-orienting or relocating the Model BD-X201MS.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
