Instruction Manual
13.5” Atomic Wall Clock
Get Started
Step 1: Slide the switch to select a time zone.
Step 2: Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to the polarity marked on the case.
Step 3: Position the clock on an exterior wall that faces Ft. Collins Colorado. During the night, your clock will automatically set itself.
Note: The hands will move to the 12:00 position and search for the radio signal. If the radio signal is not received in the first 10 minutes, the clock will start running from the 12:00 position and will continue to run. Do not attempt to reset the hands manually even though the time on the clock is incorrect. The clock is synchronizing to the WWVB signal and once the radio signal is decoded, the hands will automatically adjust to the correct time. This may take up to 5 nights.
Position Clock
•Choose a location 6 feet or more from electronics such as cordless phones, wireless gaming systems, televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.
•Position near an exterior wall that faces Ft. Collins Colorado for WWVB time signal reception.
•The antenna is available for signal reception when the front or back of the clock faces Colorado.
Reset:
If the clock does not respond to the various function modes, reset the clock by pressing the RESET button on the movement case.
Note: We recommend that you change the battery every 24 months to maintain accuracy. Remove the battery when the clock will not be in use for an extended period.

Manual Set Time
On rare occasions in certain areas, the clock may not be able to utilize the radio controlled function because of the strength of the signal or the geographic location. In this case, the clock can be set manually and used as a regular quartz wall clock.
Note: Allow up to five nights for the clock to receive the WWVB signal before manually setting the time.
Set the clock manually:
1.Press and hold the SET button for 3+ seconds to activate the manual mode. Once the clock is in manual mode, there are two ways to move the minute hand forward.
2.Hold the SET button down to move the minute hand forward consistently.
3.Alternatively, press the SET button rapidly (more than once per second) to move the minute hand forward step by step (in minute increments).
4.Use these features to move the minute hand forward until the correct time is set. The clock will automatically leave manual mode after the SET button is not pressed for 6+ seconds.
Troubleshooting
The wonderful advantage of owning a radio-controlled clock is that it is virtually trouble free. If the clock receives a clear time signal, it will set itself perfectly. If it does not receive a time signal, consider the following:
•Battery – The clock must have a fresh battery to receive and process the time signal.
•Location – Try a different location, ideally near a window. Your clock should be at least six feet from computers, TVs, air conditioners, other radiocontrolled clocks and other electrical appliances that cause interference.
•Weather – Electrical storms between you and Colorado during the night will interfere with the WWVB signal.
Daylight Saving Time:
The National Institute of Standards and Technology and WWVB encode a special DST “bit” in the WWVB transmission for DST. Your clock will read this information and automatically advance the hands one hour in the spring and eleven hours in the fall.
Arizona
If you live in an area that does not recognize DST, you must slide the DST switch OFF. To reactivate the DST program simply slide the switch to the ON position.
