1. 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 turn the instrument off after use. Remove the batteries from the
instrument if it is not to be used for a long time. Do not leave exhausted
batteries in the instrument, as they may leak and cause damage.
Clean the instrument only bywiping it with a soft, dry cloth or, when necessary,
with a cloth lightly moistened with water. Do not use any solvents, alcohol or
cleaning agents.
