Step 1: Slide the switch to select a time zone.
Step 2: Insert 1 fresh AA, Alkaline battery according to the
polarity marked on the case.
Step 3: For the best reception, please place clock on a wall that
faces Ft. Collins, Colorado. During the night, your clock
will automatically set itself.
 When the battery is installed, 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 if there is atmospheric interference.
Reset: If the clock does not respond to the various function
modes, press the RESET button on the movement case.
