Radio controlled clock no JM818WF does not receive signals. New batteries are put in. No signals on display

If you have not talked to La Cross and if you continue to have the problem, most likely it may be a signal problem. I had a similar
problem with an earlier model and found that it only worked on
the west facing wall as the signal is coming from WWVB which is the NISTtime signal radio station near Fort Collins, Colorado. Get a fresh battery, reset the clock, put it in a west facing window and leave it overnight. If it doesn't work, contact La Cross as above post.

Hello
You haven't given any details about your clock, ie, its Model number, brand name etc. Yet I posts this solution, as these are the genteral proceedings to reset a radio clontrolled clock.

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 signal during the day so it is best to install the battery late in the evening. Select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time. The time zone buttons may be pressed any time after installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. Another time zone can be selected during or after the clock has set itself. Your clock can only set itself to one of the four time zones stated above. For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement.
When the battery is installed the second hand will advance eight seconds (two seconds per step 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 near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day. If a signal is not receivable it will fast-forward the hands to the 4, 8, or 12 o'clock position and search for WWVB each

hour until a signal is received. If the time is manually set the clock will continue 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 feet away from a TV, computer, air conditioner or other household electrical appliances. The optimal location is near a window. Windows facing Colorado providing the best signal. The WWVB time signal will easily penetrate Masonry and wood framed buildings. WWVB will penetrate almost every residential building and most steel buildings if they have adequate windows. It is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. In buildings that WWVB cannot penetrate you may set the time using the manual time set button. When the clock is exposed to the WWVB signal it will automatically set the hands to the exact time. OK.

Hello
Just setup the clock once again by replacing the battery and check. If this also does not help you, the the press fitting of the second is loose. you have to open it to make it pressed firm.

OK.

Your radio should have come with a receiver of some sort for the radio signals to set itself. I had this same issue with my clock when the battery in the receiver died ... try replacing this too. It took me forever to figure out what it was because I had forgotten that it had its own radio receiver ... then once I remembered it existed, I had to find it, but replacing the battery fixed the problem. Hope that helps :-)

When the battery is installed the second hand will advance eight seconds (2 seconds per step x 4 steps). The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day.

Hope this helps I had same irratating problem
1. The RP200 is designed to automatically synchronize its calendar clock once it is brought within a range of 1500km of the Frankfurt DCF77 radio signal. When the RP200 is brought within this range, its auto-control mechanism will override all manual settings.
2. The clock automatically starts scanning the RF 433MHz signal after new batteries are inserted in the main unit. When receiving the RF 433MHz radio signal, the Radio Tower symbol starts to blink. A complete reception generally takes about 10 minutes, depending on the strength of the radio signal.
3. When the reception is complete, the Radio Tower symbol will stop blinking and remain solid
4. For an optimal reception, place the clock away from metal objects and electrical appliances (i.e. television, computer, monitor, etc) to minimize interference.
Notes:
• The unit will receive the RCC signals every day at 2am.
• The RCC signal can also be triggered by holding the key for 2
seconds in time mode.
• When the unit is searching or receiving the RCC signal (which lasts
about 5 minutes), none of the keys is working except the key.
• Press and hold the key for 2 seconds if you wish to stop to the
RCC signal search.
If the RP200 is brought outside the range of the Frankfurt DCF77 radio signal or if the signal is interfered, please set the time and date manually according to the instructions below. If the unit is located within the radio-controlled range, you may want to customize some of the clock settings.
Note: When no key is pressed for more than one minute, the unit returns to time mode (time, date and temperature display
World Time Clock
This function allows you to adjust the clock to a time zone. It is
particularly useful for travelers. Set the clock to the city you are located in, or to a city in the same time zone.
1. In time mode, press [MODE] twice to select the world time clock.
2. Press the key to select the city in which you are located.
3. Press to adjust the summer saving time function.
4. Press and hold [SET] to set the world time as the local time. When the local time is the same as the world time, the icon flashes.

I have a sharp 12 inch atomic clock...cant get it to reset and dont have instructions...please help

Have a outdoor atomic garden clock that is not receiving signal. Have changed batteries, thats not the problem. Appreciate any suggestion.
