Recommended separation distances between portable and mobile RF
communications equipment and the Welch Allyn AED 10
(IEC 60601-1-2 Table 205)
The Welch Allyn AED 10 is intended for use in an environment in which radiated RF
disturbances are controlled. The customer or the user of the Welch Allyn AED 10 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Welch Allyn
AED 10 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 determined 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: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz;
13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the
ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the
likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into
patient areas.
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
