I am trying to select UK region to use the Rugby radio time signal. I have lost the manual for the clock. After installing new batteries, Germany (GER) is the default selection. By repeatedly pressing WAVE on the back of the clock, I can make "UK" flash on the LCD but I do not know how to then fix UK as a selection. Once I stop pressing WAVE, the flashing soon stops and it always reverts to GER. Can anyone help by telling me the correct button sequence to set the radio region to UK.
