When you press the touch button to open the lock, the corresponding LED will flash repeatedly without the "secure lock" mode of the lock being active on your Classe 100X so that the buttons are only active when an audio/video link is established between the videophone and the external unit. To deactivate the "secure lock" mode: - remove the Classe 100X from the wall bracket - remove the green power supply clip - set the micro-switch for the "secure lock" function on the back of the videophone to the correct position - reassemble the green power supply clip - replace the videophone on the wall bracket
