A radio receiver in the clock is tuned to the U.S. Atomic Clock, enabling the clock to maintain split-second accuracy by automatically adjusting, if necessary, to the Atomic Clock's signals six times every 24 hours. From those signals, the clock also displays the time zone for which the user has set the clock (an adjustment for daylight saving time and leap year is automatic.) If the clock is in battery mode, pressing the snooze bar beams the time for five seconds. If the clock is plugged into a wall socket, the projection is available either for five seconds with the snooze bar or continuously if the continuous-beam control is set. --Fred Brack

The projection is perfect, larger than any clock you can get on the market. The farther you place it from the ceiling - the larger the display. NOTE! I own the blue one - I've read elsewhere that the blue and red version have a dark mask around the lcd projection - so the clock itself doesn't glow at night. The clear clock doesn't have this mask so it acts more like a NIGHTLIGHT on top of the ceiling projection. Take this into account when picking your color! 9 of 10 people found the following review helpful: By "fleup" (Christchurch, New Zealand) - See all my reviews This review is from: Oregon Scientific RM313PA/C ExactSet Fixed Projection Alarm Clock - Clear (Kitchen) Ever since i saw an ad for a projection clock in the back of a comic book as a kid, i've wanted one. My wife ordered this clock for me and after only a few days we were so used to it that we'd instinctively look at the ceiling for the time while in bed.The clock, as advertised, set itself via some mysterious atomic clock broadcast. This feature was nice for both its convenience as well as the geek factor. The clock uses its batteries for the clock mechanism. The power plug seems to be only for the projection, which will only stay on if the clock is plugged in. Otherwise, when you whack the snooze button, the projection time will show up for around 5 seconds. Conclusion: as a projector clock, i give it 5 stars. Now, as an alarm. This has to be one of the least intuitive clocks of all time for setting the alarm. You press and hold down the button with a weird icon and the word "daily". After holding it forever, you press the triangle button to change the...Read more 8 of 9 people found the following review helpful: By A Customer This review is from: Oregon Scientific RM313PA/C ExactSet Fixed Projection Alarm Clock - Clear (Kitchen) This is a cool clock, however, it takes several days after you turn it on for the clock to be programmed by the national atomic clock in Colorado. This was a let down for me, now with a little warning....you will be prepared for this. I am sure that any 10-35 year old boy would love this gift for Christmas, I would suggest however that you start it up before wrapping it up, this will give the clock time to be set. It comes with batteries so all you have to do is pull a little plastic tab in the battery compartment and the clock will start. |
