field strength in the location in which the monitor is used exceeds the applicable RF compliance level above, the monitor should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the monitor
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
The monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the monitor can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the monitor 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.
