GUIDANCE AND MANUFACTURE’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The BW-TSX / TS1 is intended for use in the electromagnetic environment specified below.
The customer or the user of the BW-TSX / TS1 should assure that it is used in such an
environment.

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 BW-TSX / TS1 is used
exceeds the applicable RF compliance level above, the BW-TSX / TS1 should be observed
to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating the BW-TSX / TS1.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE BW-TSX / TS1
The BW-TSX / TS1 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the BW-TSX / TS1 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the BW-TSX / TS1
as recommended below, according to the maximum output power of the communications
equipment.
