SV 971A User Manual – Appendixes
Note: The SA 209 (8) at the part set picture) foam windscreen protects microphone from wind
and rain. If the SA 209 windscreen is used continuously for a long period of time it is
recommended to replace it at least once a year.
Note: During continuous usage the SA 209 windscreen is exposed to different weather
conditions with possibility of causing physical damage to the foam’s structure. Therefore, it is
recommended, at least once a quarter (3 months), to check the condition of the windscreen by
examining the surface for cracks by squeezing the foam. If cracks or holes are observed, the
SA 209 windscreen must be replaced. Take care when examining the foam, as squeezing it too
aggressively can damage the surface.
Colour of the silica gel used in the desiccator (part 9) when it is dry is amber. If colour of the silica gel turns
light grey it means that the gel is soaked (wetted) and the desiccator is not able to absorb more moisture.
Colour of the silica gel is visible through the window of the desiccator. If colour of the gel becomes light grey,
the desiccator should be regenerated by drying it for 3 hours in temperature of 150°C.
Note: Desiccator should be inspected at least every 2 weeks, and more often when used in
conditions of high air humidity.
Note: Desiccator must be stored in a hermetic container when is not installed in SA 271A to
prevent absorbing moisture unnecessarily.
Note: Tripod or pole with ¼” thread is not recommended for stormy weather.
