portable and mobile RF communications equipment and the MQ3200 Pulse Oximeter
The MQ3200 Pulse Oximeter is intended for use in the electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the MQ3200 Pulse Oximeter can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the MQ3200 Pulse Oximeter 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 distanced in me-
ters (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 80MHz and 800MHz, 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.
