General Maintenance Procedures
The performance and safety of the instrument will be kept if the
following recommendations for care and maintenance are observed:

It is recommended to let the instrument go through at least one
annual overhaul, to ensure that the acoustical, electrical and
mechanical properties are correct. This should be made by an
authorised workshop in order to guaranty proper service and
repair.

Before the connection to the mains network, be sure that the local
mains voltage corresponds to the voltage labelled on the
instrument. Always disconnect the power cord if the instrument is
opened or by control / replacement of the mains fuses.

Observe that no damage is present on the insulation of the mains
cable or the connectors and that it is not exposed to any kind of
mechanical load, which could involve damage.

For maximum electrical safety, turn off the power from a mains
powered instrument when it is left unused.

Do not site the instrument next to a heat source of any kind, and
allow sufficient space around the instrument to ensure proper
ventilation.

To ensure that the reliability of the instrument is kept, it is
recommended that the operator at short intervals, for instance
once a day, perform a test on a person with known data. This
person could be the operator him/herself.

A plastic cover can be provided to protect the instrument against
the accumulation of dust. The cover should only be used when
the instrument is left unused with the power turned off.

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 dish washing cleaner or similar. The use of organic
solvents and aromatic oils must be avoided. Always disconnect
the mains conductor during the cleaning process, and be careful
that no fluid is entering the inside of the instrument or the
accessories.
