Precautions and Care of Your SGM-12, Cardioid

PRECAUTIONS AND CARE OF YOUR SGM-12

•The microphone should never be dropped or subjected to extreme shock. Store only in a padded case to protect it dur- ing transport.

•Keep the microphone away from extremely high temperatures (above 140°F or 60°C )and humidity. Avoid leaving the microphone in direct sunlight for long periods of time.

•When using the microphone outdoors, avoid getting it wet.

•After use in a high-moisture application such as a stage performance, wipe off the microphone with a dry cloth and permit it to air dry. Do not store the unit in a closed space (e.g., a plastic bag) until all moisture has evaporated.

•To protect the mic elements and ensure the longest possible useful life, it is highly recommended that for vocal appli- cations, the external foam windscreen be used over the grille. This will prevent the buildup of saliva and perspiration on the cartridge diaphragm, which degrades performance and shortens the useful life of the microphone. The foam wind- screen will also eliminate wind noise when the mic is used in a windy outdoor environment.
