Important notes
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.
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.
Color of the silica gel used in the desiccator (part 9) when it is dry is amber. If color 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. Color of the silica gel is visible through the window of the
desiccator. If color of the gel becomes light grey, the desiccator should be regenerated by
drying it for 3 hours in temperature of 150°C.
Desiccator should be inspected at least every 2 weeks, and more often when used
in conditions of high air humidity.
Desiccator must be stored in a hermetic container when is not installed in SA 277
to prevent absorbing moisture unnecessarily.
Tripod or pole with ¼” thread is not recommended for stormy weather.
