Success - thanks hay88.
For info, 9649 was the right code that I tried first but wasn't accepted.
I then tried 8052 but that was incorrect.
After yet another 30 mins, retried 9649 and held the '5' button in for around 10 seconds before the radio came to life!
Perhaps the buttons are getting worn out too!
Anyway, thanks again and I have now written the code down.
Hope I do not need your assistance again ! :-) ...
Mike
