1. The higher frequency range applies at 80 MHz and 800 MHz.
2. 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.
An investigation of the location is recommended to determine the electromagnetic environment resulting from station-
ary HF transmitters. If the measured field strength in the location in which the UNIT is used exceeds the applicable
RF compliance level above, the UNIT should be observed to verify normal operation. If unusual performance character-
istics are observed, it may be necessary to take additional measures such as reorientation or repositioning of the UNIT.
3. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

guidelines
Portable and mobile radio equipment
must not be used within the recom-
mended working clearance from the
UNIT and its cables, which is calcu-
lated based on the equation suitable
for the relevant transmission fre-
quency.
Recommended working clearance:
 1 2   P
d =
 1 2   P
d =
at 80 MHz to 800 MHz
 2 3   P
d =
at 800 MHz to 2.5 GHz
Where P is the nominal transmitter
output in watts (W) specified by the
transmitter manufacturer and d is the
recommended working clearance in
meters (m).
Field strengths from fixed RF trans-
mitters, as determined by an electro-
2
magnetic site survey , should be less
3
than the compliance level
frequency range.
Interference is possible in the vicinity
of equipment bearing the following
graphic symbol.
