Specifications and User Guide

TROUBLESHOOTING
- Primary Test: The best sound sources to use with the microphone are tuning forks, but you may want to investigate a human voice or a whistle, electronic keyboards, and other musical instruments. Make sure the sound level is in the correct range to produce good wave patterns. If the sound is too loud, the wave pattern will be �clipped off� at the top or bottom. Move the microphone further from the sound source, or turn down the volume of the sound.
