Adding external attenuators. If EMI becomes an unusually difficult problem, external devices such as an
isolation transformer or a transient suppressor may be of help. Your Service Provider can be of help in
determining the need for external devices.
Where it has been established that electromagnetic interference is affecting physiological parameter
measurement values, a physician, or a suitably qualified person authorized by a physician, should determine
if it will negatively impact patient diagnosis or treatment.
Electromagnetic Emissions and Immunity
The monitor is suitable for use in the electromagnetic environment specified in the table below. You must
ensure that it is used in such an environment.
Table 1 - Guidance and Manufacturer’s Declaration: Electromagnetic Emissions
The SRF618B6 is intended for use in the electromagnetic environment specified below. The customer or the user
of the SRF618B6 should assure that it is used in such an environment.

The SRF618B6 uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
