Features To maximise security, an electronic locking system has been incorporated as well as the provision to add a padlock should the customer desire. With the lid closed and the electonic lock actuated, the fridge function buttons cannot be accessed until the code is entered and lid has been opened. This function can either be activated or deactivated using the functions menu with an indicator included in the display to show when the fridge is locked. The fridge lid still relies on the aluminium latches to maintain correct lid sealing. Other new features include a backlit dimmable display (buttons illuminate when pressed) and DC voltage supply readout.
