Oregon Scientific Atomic Clock Not Synchronizing and Time Zone Settings

*General processes for atomic signal reception and time zone settings (See user manual for details)
Oregon Scientific Atomic Clock Signal
Most Oregon Scientific Clocks have a feature to turn on or force the clock to search for the RCC signal. The standard process to force the clock to search for the RCC signal is to press and hold the "up" or "+" button for 2 - 3 seconds. An indication that the atomic clock signal is enabled and searching for the signal is the Oregon Scientific signal icon which looks like a partial "O" will flash.
Oregon Scientific Time Zone Settings
Selecting the time zone on most Oregon Scientific clocks requires pressing the "Mode" or "Clock" button for 2 - 3 seconds to enter into the clock settings.
Typically the first clock setting is the time zone. Use the up/down or +/- buttons to change to the correct time zone. The time zone indication varies. Some Oregon Scientific clock indicate the time zone with the first letter of the time zone. Other clocks the time zones are numbered (0 = Pacific, 1 = Mountain, 2 = Central, 3 = Eastern).
After the time zone is selected allow the clock settings mode to timeout by not pressing any buttons (about 30 seconds) and the clock will return to the main screen.
*Note: On some clocks the time zone is the last setting for example the RM938. In the event the time zone is the last setting in the clock settings, press the mode or clock button repeatedly (don't hold) to cycle through each clock setting until you reach the time zone. Then proceed to select the correct time zone.

Atomic Clock Signal Troubleshooting Tips

  • The North American Atomic Signal is broadcast from Ft. Collins Colorado.
  • If the main unit receives the RF (radio frequency) transmission (atomic signal) move the main unit near a window. If the sensor receives the RF transmission try moving the sensor to another location to receive the atomic clock signal.
  • Keep the main unit away from other electronic devices that may cause interference.
  • Most units provide a method of initiating the atomic clock signal. See your user manual for details.
  • The best time to receive a signal is during nighttime hours.
  • It can take up to 24 hours to receive a signal.
  • To reset the unit, press the reset button typically located on the back of the clock or in the battery compartment. This may require a paper clip.
