I have the Sigma 160 double wireless, and this morning before my ride i was fiddling with it and accidnetally changed the language setting from english to german!! i've scoured the manuals and can't figure out how to change the language setting back to english...
on the bright side, it reports my GEM. SNELH. as 29km/h, which was pretty decent for my ride.
-Press the bottom left hand button for 3 seconds until the settings menu is displayed.
-It probably says "Sprache", German for language.
-Press the set button again (bottom left).
-Press the bottom right till it says "English" or "GB". Should be one click away.
-Then press the set button again.
-Hold down the set button again to leave the settings menu.
