I have a dunhaven quartz wall clock.My problem is

their is no way of setting it up yourself the only thing you can do is take it to a watch repair shop you can often find these in markets and the ones in the markets are alot cheaper as i dont know the area where you live i couldnt advise you on a certain place but usuall somwhere that does key cutting thse often repair watches.
this is the only problem with digital watches and alarm clocks it is difficult to do and impossible to do yourself so take it to a watch repair shop they should set it right for you for next to nothing sorry i couldnt offer you any more help but unless their is an adjuster where the battery goes their is no way of doing it yourself.
If you have only recently brought it do you still have reciept because these shouldnt be sold not set up so if you have reciept take it back and they will replace it if not and repair is only option take it into a watch repair shop this is the only sollution but shouldnt cost to much hope this is some help to you let ne know how you get on good luck

Anon, replace battery with a good strong AA Energizer or Duracell Alkaline not a cheap battery, make sure battery contact point in clock are clean and no corrosion. If this does correct the problem, the clock mechanism is probably just wearing out from age which is normal unless it is digital. Read through the links and learn how some time mechanisms can be made to work properly again. Check the attached links,instruction and guides, Good luck

How to identify and replace quartz clock movement

You may need to try and repair the quartz movement, this link will help you out.

Hi, A 8 year old can do this. On the back of the clock there should be 2 round turning nobs. 1 is for to set time (min...) 2sec is for to set timer for that hour...usually is a smaller hand on face of clock.
select hour to wake up at and set alarm Button. This is only basic set up.

First change the batteries.
Then on the back panel you will see a lot of buttons. Push the slider button from normal to time. Then after pressing the mode button you can sequentially change the time date etc. Same way for setting up alarm...push the slider to alarm and set. After you have finished put slider switch to normal.

go to www.klockit.com they make replacement movements of many types

I'm not on this field of expertise but I could try giving you some tips. These cloks work by dividing the natural oscilations of a quartz cristal in the corresponding way to form "1 second". A quartz cristal like the one in your clock will oscilate at about 14080236 times per second. Your clock uses a specialised chip in order to count these oscilations and know they form "1 second". However, the problem is the following. These clocks doesn't compensate for frequency variation over the mains power line. You should always look firts at it's power ratings and determine if it requires 50Hz or 60Hz. Even if you use an adaptor to raise/lower the tension from 110 to 220 v or viceversa, this woun't correct the problem as the adaptor will leave the frequency unchanged. Unfortunately in order to make the required adjustments you woun't need a resistor or capacitor, but a whole bunch of them in order to make a frequency divider-convertor that's stable enough to give your clock a fixed time reference. One more thing, not all components have exactly the parameters noted on them. There's another thing called Tolerance. A 1Kilo Ohm resistor with 10% tolerance (most comon tolerance) can have any value with +/- 10% of it's noted parameters, and in this example, could have any value between 900 ohm - 1100 ohm. These clocks will need components with a very strict tolerance in order to have an acurate time reference. Note that they aren't atomic clocks, they simply use a larger chip that includes most of the clock, time reference, frequency analyser and divider. An atomic clock doesn't use quartz cristals, instead it relies on the natural oscilations of the very precise Cesium izotope atom. The rest of the atomic clock is made up in a similar way as usual clocks (more fixed and small tolerance of course :) ).
