We have a BT 8500 system with four handsets.
Somehow, my wife has accidentally locked one of the handsets, and I cannot unlock it by following the instructions: "Press and hold #"
How can I unlock this problem handset?
I have tried removing batteries, waiting, and replacing them, with no success.
I have the same problem.
Is this a design flaw?
Just checked my 8500 & it works as stated.
If you have tones on for key presses, does the hash key produce a tone when pressed? Just wondering if maybe they key is stuck "on".
Does the display say "unlock" at bottom left with a padlock symbol?
