1 will not hang up
The line disconnect micro switch checks ok but the phone will not hang up from the land line, it does however show normal display responses to the hang up switch. It will just not disconnect from the land line.
When I replace the handset in the cradle the conversation will not disconnect. If I disconnect the landline from the phone the conversation will disconnect. If I reconnect the landline with the phone hung up I can hear a dial tone and then after a while a continually busy signal . Calling my landline with the cl4949 connected produces a busy signal . Is there a switching transistor in the circuit of the 4940 that is leaking?
I can use the phone as long as I physically remove the landline to hang up. The landline must remain disconnected or the line will lock up and no other phone in my home will work. With the 4940 disconnect from the landline all my other phones work ok.
Thanks,
Robert
Cette question est-elle utile ?
Hi @rcol ,
Where do you hear the dial tone etc, the receiver or the speaker?
I'm wondering if you have a faulty speakerphone button that is holding the line connected.

Both the hand set and the speaker. Speaker button releases ok. if I manually disconnect the landline each time I want to use the phone it works perfectly. As I said it will not electronically disconnect from the landline signal.
Thanks for your comment.

Hi @rcol ,
Can you test the speakerphone button contact with an Ohmmeter (with the phone disconnected from the line) to prove that the button contact is not permanently operated i.e s/c (short circuit) and that the button contact is operating and releasing correctly when the button is pressed and released?
