Not picking up signal

After the time change I realized my Oregon Atomic clock model # RMR606HGPA is no longer receiving a radio signal. I've unpluged it and taken out the batteries and I still have to set the time manualy, is there a way to make it set automaticly instead of manualy?

I got a new Sangean clock radio R22. Te atomic clock doesn't pick up the time and I can't get it to set manually either. It reads ony L 0 on the right side. I have the part that receives set in a window....

I just had the same problem which you find posted here on The problem solved itself overnight for me. I left the RCR-22 unit plugged in and searching for the signal when I woke up the next morning the time was set and the Atomic signal indicator was solid instead of flashing. It has kept perfect time since then. My only issue is that setting the alarm clock-radio is complicated.

Oregon Scientific Model 323a--Atomic clock...the atomic clock keeps setting itself to one hour behind what time it actually is in my time zone...I mannually re-set the clock to the correct time...but when...

Make sure that the clock is set for the correct time zone and that the DST (Daylight Saving Time) function is ON. Also, although not mentioned in the manuals, these clocks will typically jump and hour ahead or behind when the batteries get weak. Replace your batteries if they are more than a year old.

I got the clock from my daughter and have no manual. I keep setting the time, and it keeps changing to 2 hours earlier. I think I've pretty much figured out everything else, though this is NOT intuitive.

Hi, your clock radio is an atomic clock radio... no wait you don't need your lead underwear! it receives a signal from the atomic clock and sets the time to match it, after you set the time zone and put it on auto dst you will never have to set the time again!


The Atomic Clock obtains the accurate time with wireless technology. Same as all wireless devices, the receiving ability may be affected by, but not limited to, the following circumstances:

  • Long transmitting distance.
  • Nearby mountains and valleys.
  • Among tall buildings.
  • Near railway, high voltage cable, etc.
  • Near freeway, airport, etc.
  • Near construction site.
  • Inside concrete buildings.
  • Near electrical appliances.
  • Near computers and televisions.
  • Bad weather locally or electrical storms between you and Colorado.
  • Inside moving vehicles.
  • Nearby metallic structures.


This clock receives a radio wave much like a TV or radio. Be sure to locate it near a window or some other location where reception is good. Avoid the following locations, which can interfere with proper reception.

Synchronization signal reception can be received in Continental USA only. In other areas, you can still use this clock by making time settings manually.


  1. Place your clock in a location with optimal signal marks on the LCD.
  2. It is recommended to put the clock near a window. Please move the clock to another location if difficulty in signal reception or unstable signal marks is encountered.

Simply plug the SkyScan clock radio into any household outlet.

Battery Back-up Operation
This clock radio is equipped with alarm time memory that can be powered with a 9-volt battery (not included).When normal household power is interrupted, or the AC cord is unplugged, the battery will power the clock to keep track of the time and set alarm. When the backup battery activates, the LCD backlight is off, however, the functions of alarm and radio still operate.

To Install the Battery
  1. Remove the battery cover at the bottom of the case.
  2. Connect a 9-volt battery to the connector plug.
  3. Insert the battery in the compartment and replace the cover.
Note: An Alkaline battery is recommended. Carbon Zinc and rechargeable (nickel cadmium) batteries not recommended.

Set the Time Zone Press the SET button in sequence until you see PST(Pacific Standard Time)blinking below the time digits on the LCD. Press UP or DOWN button to select your time zone.

Daylight Savings Time
Always slide the DST switch to ON position unless the clock is used in an area without Daylight Savings Time.
**Special attention to usage in Arizona and Indiana. **Arizona and parts of Indiana do not recognize Daylight Savings Time (DST). Turn the DST off if the clock is used in these areas.

Time setting

The clock will set itself at specific time set times, this is likely to be at 0200 0400 and 0600.

You will however be required to set the time zone, the switch is likely to be on the back.

Atomic Time Synchronisation:
How does it work.
Radio set clocks and watches receive a 60-kilohertz, radio signal from the NIST the official timekeeper for the US and is located in Boulder, Colorado. Ft. Collins. they use atomic clocks and transmits this official time via high frequency short-wave and low frequency AM radio signals, satellite transmission, Internet, and via telephone.

How do i make the atomic clock work on my wireless thermometer?

The main clock need to be located close to a window.

Although the signals often pass through the walls of a house, they can also be blocked by the metal in the walls.

Also if the clock is located close to your tv or computer, the signal may be blocked.

Good Luck!

Every atomic clock in my house shows a different time!

They all receive the same signal, but it sounds like you're in an area where the signal can't get through. Check to see if your clocks have an icon that indicates signal reception (most do). If your clocks cannot lock onto the signal you may need to place them outside for a few minutes every few months.

Make sure the day is displayed instead of seconds, then homd down the + button for 5 seconds. Every 5 seconds should advance it on zone. Had same problem and just got done resetting mine this way.

Atomic Clock Daylight Savings

Your clock may need to receive a signal indicating the time change. You can try moving it to another room, or outside to see if it reads the signal. Mine didn't, so I removed the battery and reset the clock. It wasn't obvious how to do that and I didn't save the owner's manual but upon close inspection there was a tiny black button (that looks like where you would lift a cover for a battery) and pressing it allowed me to adjust to the correct time. It is a "Sharp" bought at Target a couple of years ago.

Changing the time

you can go to to see or print the user's manual.

If you don't want to get the manual, here's what you do to fix it. . . . .
*note: you need to do this anytime you change the batteries.

1) open the battery cover
2) on the left side you'll see 3 little buttons labeled a)zone, b)C/F c)reset
3) push the reset
4)push the zone button until your time zone is highlighted on the front display
5) look at the front display & if you see a blinking "radio signal" icon at upper left of time numerals
don't do anything else. The time, date, etc. will automatically synchronize your clock with the US Atomic Clock. This could take up to 10 minutes. As long as the "radio signal" icon is blinking, it's working on it. When the icon doesnt' blink, it's set. Cool, huh?
6) if the area you live in can't receive the signal from the Atomic Clock, instead of a blinking "radio signal", you'll see just a bare antennae. Since you probably set your clock manually, that's what it shows now before you do anything.
7) after you push reset & set the time zone do NOT touch any other buttons to set anything!!! (I know it's difficult to leave things alone, but just sit on your hands). Pushing the "clock" button or the up & down arrows will stop the radio signal & change to manual functions. Look at the signal icon mentioned in 5) and 6) above. If you only have the bare antennae icon. . . . . go ahead & set the time/date yourself. You have no signal.

Enjoy your clock!
