Just recieved my head back from APD so 2 weeks 4 days from when I sent it

.
Other than what I was told by Tony there is nothing new to add except that the hanset has been replaced at NO cost to me, so that on its own is an addmission that there was/is a fault on some handsets supplied by APD .
My advice to any body with this would be to contact APD via email reporting the problem ,hopefully as with me they will say no problem to wait to return it when your diving dies of for the winter .(I only returned mine as I'm servung a 1 month ban anyway !).At least then you have a record of the reply rather than just a telephone call .
Good luck
