Recommended separation distances between portable and mobile RF communications equipment
and ICS Chartr EP 200
The ICS Chartr EP 200 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
ICS Chartr EP 200 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the ICS Chartr EP 200 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:
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 has been incorporated into the formula used in calculating the recommended sep-
aration 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 inter-
ference 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.
