One of my headsets of wireless phone: CD 191 shown "not registered". I have 2 other headsets, works fine. All are fully charged. When I push the button "Menu/ok", it kept upon asked me "PIN". We never set up a pin, we then keyed in 0000" as instruction said, but no luck. Will appreciate your insight. Thank you.
