ATOMIC CLOCKS HOW THEY WORK
Sets Itself: Atomic Clock
This Sharp Atomic clock automatically synchronizes itself to the US Government's National Institute of Standards and Technology in Fort Collins, Colorado. The WWVB radio signal daily broadcast ensures that the atomic clock will always display the most accurate date and time.
In most areas, a signal can only be received at night. If your clock does not receive the WWVB signal immediately, just wait overnight and it should be set in the morning. It may take up to 48 hours.
ATOMIC SIGNAL ASSISTANCE
Most WWVB radio controlled clocks work great, as evidenced by the hundreds of thousands of units that have been sold throughout the United States. However, if you are having issues, we suggest:
◦ mounting it on a wall perpendicular to the one it is currently on (e.g. if it is on a north-south wall try an east-west wall).
◦ Place the clock along a wall or near a window that faces Fort Collins, Colorado.
◦ Locate the clock at least 6 ft. away from any computer monitors, which can cause interference (some monitors have a scan frequency at or near the WWVB carrier frequency of 60 kHz).
◦ If nothing else works, take the clock outdoors at night and power it down (remove the batteries or unplug it), then power it up again to force it to look for the WWVB signal. If it works outdoors but not indoors, you probably have a local interference problem inside your house or building. If it doesn't work outdoors at night, its probably best to return it and try a different model.
The shielding provided by a metal building might prevent the clock from working. For example, if you live in a mobile home or a house with steel siding, the clock might not work.

Nite light can't work on power supply! Only complaint is a deal killer because I bought this to view as a wall clock at night. Ithe clock is great otherwise, but there is no 5V jack where indicated on the back. There is a cutout in the back and supply specs on the back, but no jack. Returning for a replacement that hopefully has the jack. Stay tuned for updates on replacement clock.

Works great. I like how it tells me inside and outside temperature, including date in time. You can even turn the light off if you don't want it on at night.

The transmitter and clock keep accurate information. My problem is the lighting, and the LCD readability. Lighting - it comes on very bright for 5 seconds at 1am and hourly after that, which can wake you up. The lowest of the 3 light settings is still too bright and is like a nightlight. Readability - the clock must be read straight on perpendicular, or from above perpendicular in order to read it, If read from below perpendicular, the numbers fade away. So probably not readable from your bed, or if clock is tilted backward like this clock is designed to do in order to use on a horizontal desk or shelf. It needs to be mounted straight up and down vertical, and low on a wall or shelf (3'-4' high), to be seen reliably. Leaning it backward reduces readability.If you do get it mounted at the right angle and height, the 3 backlight values are good for most daylight situations. If using this in your bedroom at night, the 3 light levels are generally too bright, and the lowest level will act like a night light, and can interfere with sleeping. They really need a lower 4th level, and ideally even a voice command for changing light levels like an Alexa connection. However, then you could easily get the time from Alexa.

I've had poor eyesight all my life. So I need a clock that is very visible. This one does the trick in many ways. First, it really is an atomic clock if you have wifi. The numbers in the time are a dark grey-blue or black against a light blue background. Underneath the time is smaller font, but still visible, the indoor temp is in the same colors. In the next block you have the month, date and day, and that is black on a bright green background. It's not a pastel green or neon green. It's more like the color of new grass in spring. The final block is the outdoor temp, (you get a dongle you can hang somewhere outside) has a bright yellow background. Again, it's not pastel or sun bright. Imagine the green of a new young grass blade, but in yellow. With the different positions and different colors I have no trouble reading this clock. I will warn however, that when you first plug it in, even if you set it, it may take a few hours for it to sync with the internet. I set it up, and then ignored it for a day. The next time I looked at it, the time was perfect.

Purchased this for a clock and temperature gauge in garageThe indoor temp is off by 2-3 degrees depending on the temperature.As you can see from the attached picture I have a small white temperature gauge which shows indoor temp as 21. (Red square around it)The outdoor sensor is sitting in front on the clock (indoor) and its temp is showing as 21 as well (Green squares around it)but the indoor temp on the c lock is 2 above at 23 (Yellow circle)

The atomic clock I received as a gift at least fifteen years ago has always worked like a charm; this thing, however, is a complete piece of junk, and is a perfect example of how far the quality of things has fallen.For starters, the clock has trouble synching with the time station in Colorado. It is not able to obtain a successful synch every night, like it's supposed to. Well, I thought, even if it can only synch every two or three days, that's not too bad, and the time should be correct. Then I noticed the outdoor temperature sensor was givng wildly inaccurate readings. I had the sensor mounted in the shade, out of direct sunlight and rain, so that tells me it's just a piece of crap sensor. The indoor sensor was usually pretty close to accurate. I tried orienting the outdoor sensor vertically instead of horizontally, and that seemed to help with the readings. Ok, I thought, maybe I'll be able to keep this clock. Then this morning, at about 6:30 AM, I look at the atomic clock and the time shows 9:24 PM. And get this, the symbol that shows the clock had a successful synch during the night was on! LOL, the clock synched with the time station and got the time wrong by about 3 HOURS!! I said that's it, I'm done. This thing is a piece of garbage, and if I can save at least one consumer from going through the frustration I have by leaving a review, I'll be happy. It's very sad that we literally cannot trust anything we buy anymore. I'm putting my 15 year-old atomic clock back up on the wall and returning this piece of crap.

I have to rate it very low due to it shutting down for awhile then coming back on after 20 minutes or so. I would like to return it
