I have a Gardena WT 1030 water timer. The last battery is 10 months old and I have now replaced it as it is at my holiday home (very near to the sea) and we will not be back before April. The timer has worked very well under severe coastal conditions but the dial face has now faded very badly. I have misplaced or lost my manual. Could you please tell me how to reset it and can replacement dials be obtained. We are leaving in about 10 days so I would appreciate a urgent reply. Eddie
