I did reset the keypad to factory resetting, still the same.
Thank you for the video example, @Amixor! As a reset did not seem to fix this, try plugging the Keypad in to power to see if this audio concern persists. If it does, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support. Feel free to update us with any results!
