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 monitor is used exceeds
the applicable RF compliance level above, the MX40 should be observed to
verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the monitor.
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects,
and people.
The MX40 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or user of the monitor
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment and
the monitor as recommended below, according to the maximum output
power of the communications equipment.
In the following table, P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer and d is
the recommended separation distance in meters (m).
