If you have Call Waiting and a call waiting tone sounds while you are on a call, press TALK/FLASH to accept the waiting call.  There is a short pause, then you will hear the new caller.  To return to the original caller, press TALK/FLASH again.
A Flash function will only work if you have Call Waiting set up from the phone subscriber. 
A flash Flash feature does not operate as a Hold feature.
