| + | [title] cleaning the contacts |
| + | [* black] 1st image shows clock with back removed (after undoing 12 screws). |
| + | [* black] 2nd image shows orange printed circuit board (pcb) for leap year correction. Spray or drip contact cleaner on copper tracks of pcb. Note you can't see the contacts, but the cleaner will run into the gap. Turn the big cog around a few times to help the cleaning process. |
| + | [* black] 3rd image shows printed circuit board for month adjustment. Again spray or drip a little contact cleaner onto the pcb copper tracks. Again help the cleaning process by rolling through the months immediately after using the cleaning solvent. Dry up any excess cleaning fluid. |
