4. Care and Maintenance
The performance and safety of the instrument will be kept if the following recommendations for care and
maintenance are observed:
1 It is recommended to let the instrument go through at least one annual overhaul, to ensure that the
electrical and mechanical properties are correct. This should be carried out by an authorized workshop
in order to guarantee proper service and repair.
2 Before connection to the mains network, be sure that the local mains voltage corresponds to the voltage
labeled on the instrument. Always disconnect the power cord if the instrument is opened or by
inspection / replacement of the mains fuses.
3 Observe that no damage is present to the insulation of the mains cable or the connectors and that it is
not exposed to any kind of mechanical load that could involve damage.
4 For maximum electrical safety, turn off the power from a mains powered instrument when it is left
unused.
5 Do not place the instrument next to a heat source of any kind, and allow sufficient space around the
instrument to ensure proper ventilation.
6 To ensure that the reliability of the instrument is maintained, we recommend that the operator at short
intervals, for instance once a day, performs a test on a person with known data. This person could be
the operator him/herself.
7 If the surface of the instrument or parts of it is contaminated, it can be cleaned using a soft cloth
moistened with a mild solution of water and detergent or similar. The use of organic solvents and
aromatic oils must be avoided. Always disconnect the mains conductor and batteries during the
cleaning process, and be careful that no fluid is entering the inside of the instrument or the accessories.
8 After each examination of a patient, it should be ensured that there is no contamination on the parts in
connection with the patient. General precautions must be observed in order to avoid disease from one
patient being passed to others. The use of organic solvents and aromatic oils must be avoided.
