My wall clock no longer accepts the correct time signal.

... I'm not familliar with your particular clock, but, I'm assuming you may have a;
BATTery operated, wall-hanging, 'self-syncronizing' clock with 'hands' on it.
These are often marketed as 'Atomic' Clocks that 'keep perfect time - all the time'.
Generally these work by 'accuratizing' the Minute-hand as it approaches the 'top-of-the-hour' position (e.g. the 60th. or the zero- minute marker at '12'. They often achieve this by either 'double-Clocking' or 'half-clocking' (doublespeed or halfspeeding) the electric pulse that makes the 'SECONDs' hand advance to it's next mark. These 'SynCHRONO-ize' to a low-frequency Amplitude-Modulated (AM) radio-wave signal, (perhaps near 430Khz?) emminating from a source near "The Atomic Clock" out in Colorado (I believe).

One that I used to have hanging had recommended something like the following:

-manually adjust the time (via the small grey wheel near the BATTery, but set it about 7 to 12 minutes 'early' or before the actual correct time, (preferably at about 10 min. before an Hour).
-then remove the one " double A" . . .
... battery (for about 30sec.) and reinstall battery.
-then hang it up, and watch for the second-hand to do its 'Double-clocking' (for part of it's revolutions ) as the Minute-hand apprpaches th '12'. {note; it may take ~2 or 3 hour-cycles for the minute-hand 'to catch-up on all it's "Lost" minutes}.
(then, hopefully, your model will stay 'synchonized' there, for that 'Hour's' setting, and accept It (DST Hour value) with accuratizing Minutes. (and not go crazey over the next few days trying to get back to "Real TIME"). /mm

Once the battery is installed the clock will begin 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 even numbered 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.
What I would do, take the clock outside, it might not be getting a signal inside your house.

I do not have the same clock, but I assume the atomic receiver is the same. I found my clock went berserk if it was anywhere near anything else electronic. I had it on a dresser that was sharing space with my wireless printer. Once I relocated the printer, the clock went back to normal. You may have a different issue, but maybe check that nothing is around that would cause interference.

It sounds like it is receiving a DST signal instead of an MSF signal or vice versa depending on your country, they are one hour apart.
Unless this clock has a choice of signal settings the best way is to gently remove and reset the hour hand to the correct hour.

When you put in a new battery, the hands advance to the hour and stop. It then waits to receive a radio signal and sets the time.
to do a manual set, insert the battery and hold down the M button until the correct time. Don't go past it or you will need to continue until it comes up again. There is no reverse.

The previous answers don't fit the HD-1688 Sheng Bang clock mechanism that I have.

When the battery is installed the second hand will advance eight seconds (2 seconds per step x 4 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.

These are general quartz wall clock instructions as I dont know enough about what type/style of clock you have.

Open the access door to the dial and hands of the clock if required. Some battery-operated clock movements are sealed inside the clock case with a back panel that is screwed in place. To gain access to the hand set knob, remove the back panel screws using the appropriate tipped screwdriver.

Turn the minute hand (or turn the hand set knob at the rear of the movement if access is available) carefully counterclockwise or clockwise until the correct time is reached. Keep in mind that using the hand set from the rear would require turning the knob in a clockwise direction in order for the hands to turn counterclockwise.

Move the hour hand carefully with your fingers near the center of the hand to the hour that the clock is striking if the striking chime is not counting the correct hour. The hour hand is a friction fit hand and will move without engaging the minute hand.

Replace the back panel and tighten the screws with the screwdriver if removal of the back panel was necessary to access the hand set knob.

Close the front access door if required.

Try to move the clock to a different place. Atomic clocks work by receiving a radio signal. If it has no reception, it may do that. However, I would suspect that no reception would lead to it not setting at all(at least based on the ones I've seen) and it may be something wrong with it (i.e. having difficulty detecting where it's hands are) Good luck.

Remove backup battaries
and re insert new/or-goodbattaries in the battarey comportmane as correct +/- sign.
show the time if its start from 12:00AM
press startbutton -get time adjust mode -select correct Time and press set to mnormal mode.

I have a sharp 12 inch atomic clock...cant get it to reset and dont have instructions...please help
