I own a small cheap digital clock. Its mirror coated front. I love it. However, ive read the instructions and cannot understand how to manipulate the THREE Buttons on the side correctly. I want 12hr time. I cant get it out of 24hr mode. The 3 buttons are: M, +, -. If i hold the M button it flashes 24hr. But if i click the M again it seems stuck in 24hr. Anyone understand what will switch it to 12 hr mode to set the time? M must be Mode, but i need it to go to 12hr mode. The instructions only talk about how M is for both time modes. DUH! Pressing + only dims the numerals, or advances the hr or min.
