Proton,

Check you consumer rights in Switzerland. Under UK consumer law you would be able to reject that unit as "unfit for purpose", particularly as you have given them the opportunity to remedy the issue, and demand either a replacement or a refund. It is unacceptable, particularly with a product like the 861, that such problems persist...

I am sure the dealer is doing his best, but I would now insist, in writing, that the dealer remedy the issue permanently and within an acceptable time limit, eg 3-4 weeks, or failing that I would then reject the unit and demand a replacement/refund.

Cheers,

Mark
