Systems – shall comply with the safety requirements stated the general standard IEC 60601-1, edition 3,
clause 16. Any equipment not complying with the leakage current requirements in IEC 60601-1 shall be kept
outside the patient environment i.e. at least 1.5 m from the patient support or shall be supplied via a
separation transformer to reduce the leakage currents. Any person who connects external equipment to
signal input, signal output or other connectors has formed a Medical Electrical System and is therefore
responsible for the system to comply with the requirements. If in doubt, contact qualified medical technician
or your local representative. If the instrument is connected to a PC (IT equipment forming a system), ensure
not to touch the patient while operating the PC.
If the instrument is connected to a PC (IT equipment forming a system) assembly and modifications shall be
evaluated by qualified medical technician according to safety regulations in IEC 60601.
Note! The USB connection on the instrument has insulation protections to the patient connections.
The consequence of not following this precaution could be a too high leakage current to the patient.
IMPORTANT NOTE: The internal battery should only be replaced by an authorized service representative.
Damage to the electronics resulting from an attempt to change the battery by someone other than an
authorized representative will not qualify for repair under the product warranty.
