Precision test and measurement microphones are delicate and sensitive devices, but handled properly they can provide years of service.
- Never touch the diaphragm; microphone diaphragms are made of very thin material and can be damaged quite easily
- Never remove the grid cap and expose the diaphragm
- Send a microphone into the manufacturer for cleaning (it is possible, but not always advisable, to gently blow contaminants off the diaphragm with a light air blow bulb aimed across the surface of the diaphragm, never directly at the surface)
- When using microphones in extreme or outdoor conditions, use appropriate protection (for example, windscreens and desiccants) to reduce the effects of wind, rain, and condensation
- Hand tighten microphones – do not over tighten
- Never cover the microphone grid cap, except with a windscreen or other Larson Davis microphone protection (the preamplifier cap looks as if it fits - it should never be placed on the microphone)
- Never cover the preamplifier vent
- Take care not to drop the microphone
- Store the microphone either attached to a preamplifier in a secure case or in its own protective case in a clean, dry environment
