We test every sound button to make sure that it records and playbacks properly. Sometimes, for a number of the buttons manufactured in the past, the test sound remained on the button after shipping. Under normal operation, this test sound would never be heard. However, under certain conditions, customers may be able to hear the test sound. If you switch your button to record mode then press and hold the button until you hear a beep, any previously recorded sound will be erased.
