VERY basic Roomster 1.2.  Has most basic display (no menus), which now shows a spanner and "service", which I would like to be rid of. No instructions on how to do this in manual, and have tried permutations of pressing trip button and ign on/pff. There is no little button to turn, as mentioned in some posts. Determined not to go near dealers. So...any ideas, please? Some cheapo reset gadgets on ebay but anyone tried one?  Thanks for any help. H.

Hi, give a try this method
