Re: Please Help!!! I have IBM-3900SL cordless phone. ...
You need to register the base and handset... Here is how to do it:
Press and hold the "CH" button on the right side of the handset and the
press and hold the "Page/Find" button on the base.... The handset
should say "Registered" in a few seconds
