a The ISM (industrial, scientific and medical) bands between 0,15 MHz 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 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to
18,17 MHz,
21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to
54,0 MHz.
b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the
frequency range 80 MHz to 2,7 GHz are intended to decrease the likelihood that
mobile/portable communications equipment could cause interference if it is inadvertently
brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated
into the formulae used in calculating the recommended separation distance for transmitters in
these frequency ranges.
c 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 DL-DF01 is used
exceeds the applicable RF compliance level above, the DL-DF01 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the DL-DF01.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
10.3 Recommended separation distances
Recommended separation distances between
portable and mobile RF communications equipment and the model
DL-DF01
The Model DL-DF01is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of
the Model DL-DF01 can help prevent electromagnetic interference by
