APPENDIX
Declaration – Electromagnetic Emissions
The 3M Littmann® Electronic Stethoscope, Model 3100, is intended for use in the electromagnetic environment specified
below. The customer or the user of the Model 3100 should assure that it is used in such an environment.
Emissions test
Compliance
RF emissions CISPR 11
Group 1
RF emissions CISPR 11
Class B
Harmonic emissions IEC 61000-3-2
Not applicable
Voltage fluctuations/flicker emissions
Not applicable
IEC 61000-3-3
Electromagnetic environment –guidance
Model 3100 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.
Model 3100 is suitable for use in all establishments, including
domestic establishments and those directly connected to
the public low-voltage power supply network that supplies
buildings used for domestic purposes.
