Hello, same with me! It is the second time this has happened.
First time, I send it back to seller and they fixed the scope.
Since this is a normal behaviour for this type of device, I would like to be able to repair it all alone, without waiting several days (or weeks) for the seller.
Can I have this recovery package, please?
