1. Don't blow into a microphone to see if it's on. Blowing into a microphone can expel moisture into a microphone and besides being disgusting can damage the microphone diaphragm. Instead, lightly tap the microphone with your finger.

2. Do not speak directly into a mic. You'll usually create a popping sound, especially if you make a "P" or "T" sound. A windscreen on the mic will help to reduce this, but it's best to improve technique by speaking across the mic rather than into it.

3. Do not place a clip-on mic under clothing. Although out of sight, the mic will pick up rustling noises as clothing rubs against it, and it will muffle sounds. It is better to clip it on a lapel or wear it around your neck. For stage or TV productions, lavaliere mics can be concealed under clothing if first placed into a silk pouch, which reduces noise-causing friction.

4. Don't abuse your microphone. Don't drop it, subject it to shock, or hold it dangling by the cable, etc. It is a delicate instrument and may be expensive to repair or replace. Store it in a clean, dry place when not in use.

5. Do not hold your microphone down or pointed in the direction of a monitor loudspeaker. If the microphone is on this can produce feedback, which can result in damage to loudspeakers or your hearing.
