Nil is more precisely measured than time!

And aught keeps rail of time more precisely and trouble free than our radio controlled clocks. Since the beginning of time, human being has been fascinated with the measurement of time and has devised more than accurate machines to trap and measure out time. Today, time is precisely measured in the United states by the most accurate clock in North America, the Atomic Clock of the US National Institute of Standards and Applied science, Fourth dimension and Frequency Division in Bedrock, Colorado. A squad of diminutive physicists continually measures every second of every day to an accuracy of x billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time indicate is continuously broadcast throughout the United states of america at sixty kHz to take advantage of stable long moving ridge radio paths institute in that frequency range. Radio waves at these low frequencies employ the earth and the ionosphere as a moving ridge-guide and follow the curvature of the earth for long distances.

The built in antenna arrangement will receive the WWVB betoken anywhere in North America within 2000 miles of Fort Collins where long-moving ridge radio reception is undisturbed. A microprocessor activates the receiver and processes the time indicate from Fort Collins overnight.

Through the radio signals, our radio controlled clocks always keep precise time. The changeover from standard time to daylight savings time, and vice versa, takes identify automatically with the same precision.

Additional details

To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of long wave radio signals it is normally not possible to receive a indicate during the twenty-four hour period so it is all-time to install the battery belatedly in the evening. Select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Fourth dimension, CT-Central Time, ET-Eastern Time. The fourth dimension zone buttons may exist pressed any time later installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no fourth dimension zone is selected the clock will default to Pacific Fourth dimension. Some other time zone can be selected during or subsequently the clock has set itself. Your clock can only fix itself to i of the iv time zones stated above. For time zones outside of PT, MT, CT or ET you must manually gear up the time using the Transmission Fourth dimension set push button on the dorsum of the move.

Daylight Savings Time Adjustment.

If yous live in Indiana or Arizona y'all will wish to disable the DST function. After setting your clock press the small button labeled "DST" located just in a higher place and between the ET and CT Time Zone buttons on the back of the movement. Your clock will no longer observe DST.

Transmission Setting

Diminutive Clocks may also exist prepare manually and be very authentic. But insert the battery, press your time zone and and then press the flap but above the left side of the battery. Hold until you achieve the correct time and so release. Your clock is now an accurate quartz clock until information technology volition discover the signal. Your Atomic clock will withal go on to look for the signal and get-go adjusting itself automatically.

When the bombardment is installed the second manus will advance 8 seconds (2 seconds per footstep x four steps). The clock is now searching for a signal. For the initial setting, it is recommended to stand the clock in an upright position virtually a window. Inside five minutes the clock will either receive the WWVB signal and set up itself to the exact time, or it will determine that the signal is not receivable at its current location and time of twenty-four hour period. If a signal is non receivable it will fast-forwards the hands to the iv, viii, or 12 o'clock position and search for WWVB each hour until a signal is received. If the fourth dimension is manually set the clock volition keep to periodically search for a signal and automatically reset the hands when the signal is received.

Select a location to place your radio controlled clock where it will be at least six anxiety away from a Idiot box, computer, air conditioner or other household electrical appliances. The optimal location is near a window. Windows facing Colorado providing the all-time signal. The WWVB time signal will hands penetrate Masonry and wood-framed buildings. WWVB volition penetrate almost every residential building and most steel buildings if they accept adequate windows. It is not possible, however, for WWVB to penetrate nigh indoor shopping malls and rooms in the middle of large office buildings that do non have windows. In buildings that WWVB cannot penetrate you may set the fourth dimension using the manual fourth dimension set button. When the clock is exposed to the WWVB point it will automatically gear up the easily to the exact fourth dimension.

Our Rwave, Atomic, Radio Controlled clocks do not receive or process radio-controlled time signals from Germany'due south DCF 77, Japan'south J Ga As, or England's MSFs atomically regulated transmitters. Our Radio Controlled clocks can be manually prepare and used anywhere.

If your clock did not gear up the beginning fourth dimension or after daylight savings time change, endeavor the following instructions:

1) Take out the battery and identify the battery in astern for about 10 seconds, then replace it over again in the correct position.

ii) Just afterwards replacing the battery, press the Fourth dimension Zone push button for nigh v seconds on the back that corresponds with the fourth dimension zone where you are located.

3) Shortly after the easily should showtime turning 20 times their normal speed and stop at 4:00 or 8:00 or 12:00. This means the clock is now looking or waiting for the signal and the clock movement is good.

4) Place the clock near a westerly window overnight then the clock should reset overnight and read the correct time.

**If you had previously pushed the transmission mode flap (switch), accept a pen or paperclip and make sure information technology is pulled out in the off position.

If you alive in the Eastern Time Zone, you should manually gear up your clock using the following procedure:
1. Take the battery out of the clock.
2. Printing the manual fourth dimension setting tab on the back of the clock 15 times.
3. Put the battery back into the clock.
4. The clock will become to iv:00, 8:00, or 12:00 and stay at that place while waiting for the signal.
5. Immediately after your clock stops at 4:00, viii:00, or 12:00, push and hold the transmission fourth dimension set tab until you get to the correct time.
If you release the button at the wrong time, take the battery out and get-go again.

These clocks will automatically continue to check and arrange later April i.

Troubleshooting

The wonderful advantage of owning a radio-controlled clock is that it is about trouble-costless. If the clock receives a articulate signal information technology will set itself perfectly. If it does non receive a signal consider the following:

Bombardment - The clock must have a fresh battery to receive and process the fourth dimension betoken.

Location - Try a different location, ideally almost a window. It should exist at to the lowest degree six feet from computers, TVs, air conditioners, other Radio-Controlled clocks and other electric appliances that cause interference.

Weather condition - Electric storms between you and Colorado during the night will interfere with the WWVB signal.

Daylight Savings Time

The National Institute of Standards and Technology and WWVB encode a special DST "fleck" in the WWVB transmission for DST. Your Radio Controlled clock volition read this information and automatically advance the hands 1 hour in the spring and eleven hours in the fall.

Arizona and Indiana

If y'all live in an surface area that does non recognize DST you must press the (unmarked) DST push for one 2nd to deactivate your clock's DST program. To reactivate the DST plan merely press the DST button again for i 2nd.

Oft Asked Questions

Q. How long will the battery final?

A. A good AA element of group i bombardment will last over one year. If your clock is located in an surface area with little interference

where it tin can rapidly receive a signal the battery tin concluding much longer than i year.

Q. Can a Radio Controlled clock be used outdoors?

A. Yes, but only in a dry surroundings and in a temperature range betwixt 41 F and 131 F. The clock is NOT

h2o-resistant.

Q. Can the Radio Controlled clock exist wired to control timing circuits?

A. No.

Q. Why does the second-paw move only in one case every ii seconds?

A. When the battery drops below 1.25 volts the clock indicates that it is time to change the battery by advancing the second hand in two-second steps. The operating voltage range is i.25 to ane.75 volts.
