by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
a
phones 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 models model name are used exceeds the applicable RF
compliance level above, the models model name should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the models model name.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

Recommended separation distances between portable and mobile RF communi-
cations equipment and the models BW-MTX1
The models BW-MTX1 are intended for use in electromagnetic environment in which radiated RF
disturbances is controlled. The customer or the user of the models BW-MTX1 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the models BW-MTX1 as recommended
below, according to the maximum output power of the communications equipment.
Rated maximum output

0,01
100
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmit-
ter in watts (W) accordable to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz. the separation distance for 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.
