Pettersson u256 USB Ultrasound Microphone
Handling precautions
The u256 is not waterproof and should be protected against the elements if used e.g. under humid conditions. The housing
and circuit board are relatively insensitive to humidity, but the microphone element and USB connector may require
protection.
The USB plug should be handled with care. Applying excessive force on the plug is likely to cause damage. This is
particularly important when the microphone is plugged into a host device (e.g. a smartphone).
