popping does not necessarily damage the ribbon element but may produce unacceptable
preamplifier overload and could cause damage to speaker systems.
3. Do not expose the microphone to liquids or caustic smoke.
4. To avoid hum, do not expose the microphone to strong alternating electromagnetic fields,
such as the power transformers in amps.
5. Use a soft cloth to clean the microphone body. A small amount of denatured alcohol can be
used to remove fingerprints and other stains.
6. Keep metal filings away from the microphone at all times.
7. When not in use, store the microphone in its protective wooden case.
8. Leave disassembly of the microphone to a trained technician. Disassembly of the microphone
will void your warranty. There are no user-serviceable parts inside.
Caution!
Keep recorded tapes, spring-wound watches, and personal credit cards using magnetic coding
away from the microphone to prevent possible damage caused by the transducer’s powerful
magnets.
