What Should I Pay Attention to When Using WWVB Features?
Please select the correct time zone before RCC search.Make sure your location can successfully receive the time signal, place the clock in an open place or near a window with good signal.Please place the device more than 3.28 feet away from sources of interference such as TVs, computer, microwave, radio, etc.Closed areas such as airports, basement, factories and areas, in which reinforced concrete was used in the walls, are not recommended.If the RCC time signal is not received successfully and the time automatic setting fails, you can also cancel the radio reception and set the time manually.Sometimes in extreme weather or weak signal or other disturbances appear nearby, the clock may also appear to receive the wrong time signal instruction.For more information, please refer to the WWVB web page of NIST.After 48 hours, if the clock hasn’t received the signal, or if you have any queries, problems or do not understand any parts of these instructions, please write to us.
How do atomic clocks work?
Atomic clock is an extremely accurate timepiece. Most atomic clocks in north america use WWVB’s transmissions to set the correct time automatically. They can receive the time signal transmitted by the national institute of standards and technology (NIST). The NIST broadcasts the time signal (WWVB,60KHz) continuously from Fort Collins, Colorado. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter. The atomic clock has a built-in RCC receiver for automatic synchronization of WWVB radio broadcasts. Atomic clocks will always be accurate to within one second when receiving daily WWVB updates.

Atomic Clock for Wall or Desk
It can be easily hung on a wall or placed on a tabletop using the sturdy fold-out stand. LCD large display and large digits of the clock make this beautiful clock ideal for home, office, school, hospital, etc.
The outdoor temperature and humidity are displayed by the outdoor sensor, which collects the surrounding outdoor temperature and humidity information through the flowing air and transmits it to the clock. To ensure accurate temperature and humidity sensing, place the outdoor sensor out of direct sunlight or rain, and away from any heat sources or vents. The sensor can wirelessly receive the transmitted signal within a range of 330 feet, so that the family can know the indoor/outdoor temperature and humidity at any time.

What I like about this new wall clock
I like the clock’s display size, numbers are visible from afar, 5-10ft , provides accurate temperature readings internal/external, and overall easy to setup

very large read out
this clock is great, the wife and I have a large living room and the clocks large numbers are visible from up to 20 feet away. Easy to set up and has indoor and outdoor temps, with humidity.

Good clock!
We love this clock! It was working great until a cat jumped on our mantle and knocked it down. I don’t know what’s wrong with it now, some of the numbers don’t fully light up and we can’t figure out how to change the time. I’ve changed batteries and messed with it for a long time until I realized I can’t fix it. I don’t have the heart to throw it away cause it still tells time, the wrong time but it does work. The size is great! I plan on buying another one soon to replace this one but just haven’t yet. The temperature seems reliable, and it’s very easy to read from across the room!

Works well, but uneven weight distribution
Bought this to replace a similar one (different brand) with a bad outdoor temp sensor. Numbers are a little smaller than the old one, but function is good and this one has humidity which is a plus. Knocked off one star because when using just the center mounting hole on the back the clock won’t stay level because of lopsided weight distribution. It does have a total of 3 mounting holes, so I used the two outer ones which is fine. But you have to do a good job leveling the nails in the wall.

very pleased with the LFF 15″ Atomic Clock *updated
We’ve had the LFF 15″ Atomic large characters clock 90 days now and have been thoroughly pleased with it. We’ve hung ours in a 90yo’s bedroom, where having the large digits has been ideal. We liked that it’s not backlit seeing as how it’s in a bedroom. The LCD numerals are dark and well contrasted against it’s slightly blueish hue background. Having the date and day displayed makes great for early morning wake ups/reminders. The dual temperatures and humidity percentages, that we’re using for outside & inside (see more momentarily), is awesome, and thus far accurate. The atomic connection has been set-it-and-leave-it thus far (with one daylight “savings” time change under our belt).I am impressed with the range of the sensor sending strength, as it’s on opposite ends of our 1430sq ft home with a brick wall and kitchen in between it and the bedroom it’s in. i did have to relocate the sensor unit from under an east side eve, as the morning sun was warming it (and/or the brick wall) and skewing the early day temps. I moved it to the north side, which gets zero direct sun year around, and it’s matched internet reported temps ever since. Speaking of the sensor, while i like the display of temp & humidity directly on it, note that it’s a very small (tiny) display, relatively, so it requires being pretty much in hand’s reach distance to read it (i was hoping to be able to see it from inside through our kitchen window, as dual feature, but being LCD and tiny, again, relatively, it didn’t work for that for us); being able to compare it with the inside unit is neat though. The occasional pulsing red LED battery indicator is visible from longer distances and is a nifty feature as well. Back to inside, using it as a wall clock, we’ve not used the alarm or other daily-type options, so can’t speak to those. We haven’t had low batteries yet, so also can’t speak to it’s feature of having a low battery notification. We feel we’re getting out $65 (+sales tax) worth with it, thus far…*09-2023 update:3 times now in about as many months, upon awaking in the morning we find the time wrong, twice including day, date, month & year (temperatures and humidities unaffected). Each of the first two instances, we reset it to have it stay accurate for awhile, to then eventually be off again. The last instance was merely that the time was 2 hours off*late. One other time, the date was off by by several years (into the future) along with month/day, plus time off, PM instead of AM. This was with the device set to nightly auto-check the atomic signal; we’ve now disabled that feature to monitor the issue further…(additionally, fwiw, we’re still on original batteries, in both the clock and the sensor; have had no low battery signal thus far; we’re not using the alarm feature)

Not a reliable time keeper.
Loses track of time. Here I sit at 11:33 am, and the clock reads 7:33 pm. In a day or two, it will return to the correct time all by itself. Not a reliable timekeeper. Other than timekeeping, I love the clock. Oh, this is my second one. I returned the first one to Amazon for the same reason, thinking I just got a bad one the first time.

Love the large numbers, makes it easy to read. Set it up and don’t have to change for Saving Time.

Date and Temperartuire sizes could be larger, all Time size ok, date format should be able to change for example to Day-Month-Year.

Me gusto, todo conforme lo anunciado, solo me hubiera gustado que tuviera idioma español. Tal vez un poco caro.
