To enable this feature; open the iD control application, and navigate to the settings tab.
The settings tab will now appear within iD Control, and the ‘volume recall’ option can be accessed here:
Enable this option to allow your iD2 to remember your last used volume setting. Disable this option if you would like your iD2 to forget the last setting, and always boot up with a monitor level of -128.
