Manufacturer’s declaration – electromagnetic immunity
The custo watch holter recorder (consisting of custo watch and ECG transmitter)) is designed for use in the elec-
tromagnetic environment stated below. The customer or user of the custo watch holter recorder should make
sure that it is used in such an environment.
1) The ISM bands (EN: Industrial, Scientific and Medical, i.e. frequency bands used for industrial, scientific and
medical purposes) between 0.15 MHz and 80 MHz are 6.765 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.
The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz; 3.5 MHz to 4.0 MHz;
5.3 MHz to 5.4 MHz; 7 MHz to 7.3 MHz; 10.1 MHz to 10.15 MHz; 14 MHz to 14.2 MHz; 18.07 MHz to
18.17 MHz; 21 MHz to 21.4 MHz; 24.89 MHz to 24.99 MHz; 28 MHz to 29.7 MHz and 50 MHz to 54.0 MHz.
