the polarity marked on the case. Replace the battery cover.

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, 4:00 or 8:00 position and
search for the radio signal. If the radio signal is received the time

on the even hours. Once the radio signal is decoded, the hands
will automatically adjust to the correct time. This may take up to 5
nights.

the hours are off, hold the correct time zone button for 5 seconds
to correct.
