Recommended separation distances between portable and mobile RF
communications equipment and the Welch Allyn CardioPerfect Pro
Cardiograph
The Welch Allyn CardioPerfect Pro Cardiograph is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Welch Allyn CardioPerfect Pro Cardiograph
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Welch Allyn CardioPerfect Pro Cardiograph 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.
