Daylight Savings Time Changes

If the time does not change on your radio controlled clock (RCC):
  • Make sure Daylight Savings Time (DST) is set properly. All states except Hawaii and Arizona observe Daylight Savings Time. If you observe DST, make sure this setting is turned ON. The default is OFF.
  • Be patient. Wait at least one week before contacting Ambient Weather. The RCC is a shortwave signal originating near Fort Collins, Colorado, and travels thousands of miles by bouncing off the ionosphere. The signal is better at night due to solar interference during the daytime. The farther you are from Colorado, the weaker the signal. Urban environments can also effect the signal strengh.
  • Locate the console at night near a window or outer wall, and away from other radiating sources, like wireless routers or TVs. This will insure the best reception possible.
  • Test and replace the batteries in the console, if required. Low batteries are often the cause for weak reception.
  • Check your Time Zone Setting. Make sure your time zone is set properly in the display console settings. All times zones in the USA are negative.

Caveats and addendums:
  • WS-5300: The WS-5300 does not have a DST setting. Subtract one time zone during DST to compensate for the time change.
  • WS-1173A: The WS-1173A sunrise and sunset depend on the DST setting. If your sunrise and sunset are off by one hour, subtract one time zone during DST to compensate for the time change as a temporary work around.
Frequently Asked Questions:
  • I turned on DST. How come it is not showing on the screen? It will require an update from the atomic clock in Colorado to activate the icon once it is set to ON. Please allow up to one week for this change.
  • Can I manually set the time? Will it affect the RCC automated feature? Yes, you can manually adjust the time while waiting for the atomic clock to update It will not cancel the RCC feature.
