WallarGe Atomic Clock

About RCC Atomic Clock.

As Radio Controlled atomic clock, it can receive the time signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3 atomic clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts the time signal (WWVB,60KHz) continuously from Fort Collins, Colorado. This signal can be received anywhere in the continental USA and Canada that long wave (AM) radio reception is possible with a portable radio. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter.

Therefore, your clock will receive the signal within the broadcast range anywhere an AM signal can be received; generally, the time signal cannot be picked up in massive metal and concrete structures unless near a window. In addition, some environmental effects (see below) may affect the transmitting distance and reception. For more information, please refer to the WWVB web page of NIST.

Self-setting Every Midnight.

This digital wall clock will automatically receive the time signal every day at midnight and makes any required adjustments to the time setting. That is to say, it updates the time every night automatically, so it is more accurate than any other ordinary electronic clock. Therefore, it is very suitable for those friends who have high requirements for time accuracy.

Note 1: Frequent use of this feature may affect battery life.

Note 2: 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.

Note 3: 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

About Outdoor and Indoor Temperature Monitor.

This digital clock's indoor temperature monitoring relies on a built-in Swiss high precision SHTC3 indoor temperature sensor, and its outdoor temperature monitoring is mainly through the radio frequency (RF) transmitter to collect the outdoor temperature and then send the temperature information to the receiver, and finally display the temperature on the clock.The maximum receiving distance of outdoor temperature is 330ft.

Temperature Detection Range.

1.Operating temperature is from -40℉ to 158℉ (-40℃ to 70℃)

2. The indoor temperature display range is -40℉ to 158℉(-40℃ to 70℃). Indoor temperature is measured once every 10 seconds.

3. The outdoor temperature display range is -40℉to 158℉ (-40 ℃to 70℃).The outdoor transmitter temperature is measured once every 10 seconds

but transmit RF signal every 32 seconds.

4.Temperature accuracy +/- 0.1℉(+/- 0.1℃)

Who Needs Atomic Clocks More?

This is an atomic alarm clock for anyone.However,since atomic clock will automatically receive the time signal every day at midnight and makes any required adjustments to the time setting.So it is more accurate than any other ordinary electronic clock. Therefore, it is very suitable for those industries and friends who have high requirements for time accuracy,such as scientists, stock traders, doctors, nurses, teachers, lawyers,etc.

Tip: Since in the self-setting (RCC)mode, the clock will automatically turn on to receive radio signals every night, so the battery may consume quickly,

or sometimes in extreme weather or weak signal or other disturbances appear nearby, the clock may also appear to receive the wrong time signal instruction.Therefore,it is suggested to use self-setting (RCC) function reasonably,such as turning on RCC function once every week or according to your own requirements for time accuracy.

What Should I Pay Attention to When Using WWVB Features?

1. Make sure that your location can successfully receive the time signal.

2. Put the clock in an open area or near a window with good signal.

3. Don’t put the clock with iron household items.

4.The clock’s default auto daylight saving time is on, time format is 12 hour, and the time zone is eastern time zone.If you need to change these default settings, you need to set them before the clock starts searching for RCC time signal.

Great Gift Idea.

This digital clock has beautiful package,good appearance design,a variety of excellent featuresso,so it can be great present idea.You can gift it on various occasions such as Thanksgiving Day, Christmas, Halloween, birthdays, wedding or any relate events.
