TABLE 5 Recommended separation distances between portable and mobile RF communications equipment and
the Cook Doppler Blood Flow Monitor (DP-M350) for the Cook Doppler Blood Flow Monitors (DP-M350) that are
Recommended separation distances between portable and mobile RF Communications equipment and the
The Cook Doppler Blood Flow Monitor (DP-M350) is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Cook Doppler Blood Flow Monitor (DP-M350)
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Cook Doppler Blood Flow Monitor (DP-M350) 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.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
