I recently bought this ski with 116 hours on it and it has been running great but i just noticed when I put the key in it beeps twice which i know is normal but "maint" shows up along with a red light, then when i start the ski the light goes out and "maint" disappears. Is this a normal start-up? Also if i don't start the ski but keep the key in i get 4 short beeps ever few seconds until i start it or take the key out, is this just letting me know the keys in and if so is there a way to disarm it? Thanks!
