Guidance and manufacture's declaration – electromagnetic immunity
The Electrocardiograph is intended for use in the electromagnetic environment specified below.
The customer or the user of Electrocardiograph should assure that it is used in such an
environment.

NOTE 1 At 80 MHz and 800 MHz, 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.
