Interference is possible in the vicin-
ity of equipment bearing the follow-
ing graphic symbol.
1. The higher frequency range applies at 80 MHz and 800 MHz.
2. The field strengths of fixed transmitters, such as base stations of
radiotelephones and mobile agricultural radio broadcast services,
amateur radio stations, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. A site
survey is recommended to assess the electromagnetic environment
due to fixed RF 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 characteristics are
observed, it may be necessary to take additional measures such as
reorientation or repositioning of the UNIT.
3. Over the frequency range 150kHz to 80 MHz, field strengths should
be less than 3 V/m.

Working clearances
Recommended working clearances
between portable and mobile RF
communication devices and the UNIT The UNIT is intended for operation in an electromagnetic environment,
where radiated RF interference is checked. The customer or the user of
the UNIT can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the UNIT - depending on the maximum
output power of the communication device, as shown below.
