User manual of Colson pulse Oximeter OxyPad – Home ref. CMS50DL / Pro ref. CMS50D
RF communications equipment and the EQUIPMENT or SYSTEM –
The oximeter is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the oximeter can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the oximeter as recommended below, according to the maximum output power of the
Rated maximum output

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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.
