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.
f. Field strengths from fi xed 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 fi xed RF transmitters,
an electromagnetic site survey should be considered. If the measured fi eld
strength in the location in which the LATITUDE Communicator is used exceeds
the applicable RF compliance level above, the LATITUDE Communicator
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or
relocating the LATITUDE Communicator.
g. Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less
than 3 V/m.
h. The compliance level used in the following sub-bands is higher than in the
table: 380 – 390 MHz at 17 V/m, 430 – 470 MHz at 14 V/m, and 800 – 960
MHz at 24 V/m.
i. The compliance level used in the following sub-bands is higher than in the
table: 1700 – 1990 MHz at 24 V/m, and 2400 – 2570 MHz at 24 V/m.
