4. Recommended separation distances between portable and mobile RF
communications equipment and this medical LCD monitor.
The medical LCD 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 medical LCD 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 meters (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.
2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
