Query: Piece of Junk

The mode is selected with a slider bar on the top (time set, alarm set, calendar set, etc). After about three weeks the only mode that would activate was "calendar set" no matter where the slider was placed. So, now I can't set the alarm to a new time. So, when you buy a low cost alarm, made in China, this is what you get - poor quality. My other minor complaint is that the display is really too bright for a dark room. The one plus is the battery backup which keeps the time so you don't have to reset the clock after a power outage.
