This Acctim radio-controlled travel alarm is the perfect companion to keep you on track whenever you're away from home. It's just as easily viewed at night thanks to Smartlite® technology, where a bright backlight illuminates the display as the room gets darker and turns off again during the daytime to prolong the battery life. Using radio-controlled technology, the clock sets up automatically, handily adjusts to summer and winter time changes on its own and keeps time super accurately. It receives a signal from the atomic transmitter which is so accurate it loses just one second in a million years. It also includes a folding case with a button locking switch and a beep alarm with a snooze function so you can get a little extra shut-eye when you need it.
