The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz;
13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands
between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3

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 theFDBP-A10BL is used
exceeds the applicable RF compliance level above, the FDBP-A10BL should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as

Recommended separation distances between
portable and mobile RF communications equipment and the FDBP-A10BL
The FDBP-A10BL is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the FDBP-A10BL can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the FDBP-A10BL as recommended below, according to the maximum output power of the communications
equipment

For transmitters rated at a maximum output power not listed above the recommended separation distance d in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according 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.
