Instrument Care

Do not attempt to remove the mesh cover from the microphone as this will cause
damage and affect the accuracy of the instrument.

Protect the instrument from impact. Do not drop it or subject it to rough handling.
Transport it in the supplied carrying case.

Protect the instrument from water, dust, extreme temperatures, high humidity and
direct sunlight during storage and use.

Protect the instrument from air with high salt or sulphur content, gases and stored
chemicals, as this may damage the delicate microphone and sensitive electronics.

Always switch the instrument off after use. Remove the batteries from the instrument if
it is not to be used for a long period of time. Do not leave exhausted batteries in the
instrument, as they may leak and cause damage.

Clean the instrument only by wiping it with a soft, dry cloth or, when necessary, with a cloth
lightly moistened with water. Do not use solvents, abrasives, alcohol or cleaning agents.
