Maze Waterproof BT Spkr w/LCD Display

How to change it from 24 hour to 12 hour? The directions for the clock are wrong. You have to press the FM button to toggle between Bluetooth/FM/Clock modes. But once you’re in clock mode, is there no way to change it from 24 hour to 12 hour display?

Have you tried contacting Maze to see if they can help?
