How do you set the clock? Mine is an hour ahead and I can't figure out how to set it back. I don't have a manual either...

Not sure if this will work for you but I had a used one and when I set mine at 12 it would chime 9. So I turned my clock backwards to eleven then ahead to 12. When I did that it chimed 10. I kept back and forth till 12 chimed 12.Then it was reset.

To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening. Select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time. The time zone buttons may be pressed any time after installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. Another time zone can be selected during or after the clock has set itself. Your clock can only set itself to one of the four time zones stated above. For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement.
When the battery is installed the second hand will advance eight seconds (two seconds per step x four steps). The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day. If a signal is not receivable it will fast-forward the hands to the 4, 8, or 12 o'clock position and search for WWVB each
hour until a signal is received. If the time is manually set the clock will continue to periodically search for a signal and automatically reset the hands when the signal is received.

I feel your pain, I am in the same position. After endless mucking around I finally figured it out. By the way, this is for my model P10034AP. Press these buttons: - Cancel [to abort anything currently underway] Clock [to set the time] Cancel [to clear the time allowing input] nnnn [the 4 numbers HH:MM in 24 hour time] Clock [to set the new time]
Hope that helps :) Cheers Jonathan Barton
