Tested/working. Base/cradle only (w/adapter). No handset or other accessories included. If its not in the picture, its not included.
Your current handsets may need to be sync'ed (aka "registered") to the new base. If your handsets won't talk to the base please see the manual for your system. You can google the model number with the keyword 'manual PDF' to find it online if you don't have it. If you need help, please ask.X
