BT8500 additional handset will not connect to base
I have just bought the BT8500 and set them up for charging. I came back to them 12 hours later to find the additional handset had no display and kept flashing on and off. I can't access any menu on the phone as its loosing connection all the time. I read about resetting all the bases so did this. The phones display came on and I was able to reset everything. However once I connect the base handset (handset 1) it reverted back to flashing intermittently as if it's searching again. Anybody else had this problem? I even set the phones side by side to enable them to connect to each other!!!
