lrp sphere 07 spec problems

[birdy b4]

on my lrp sphere 07 speedo the set button has broken , it will only work if i push very hard and then only works sometimes , also am i right in thinking that this model has 8 punch settings ? because i seem to remeber it does but whilst trying to set it up today ive discovered that sometimes it goes back to setting 1 after setting 6 and sometimes setting 5 ! does anyone know of anything i can do ? and who is the current lrp distributer in the uk ? would it be worth giving them a call ?
