Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Bill.
The handset model you would need is the kx-tgea20, which you can order online here: http://amzn.to/2ar3Tu7
note that your system can accommodate a maximum of 5 handsets total.
When you get the new one, you'll need to register it:
Charge the battery for at least 8 hours first
then key in Menu#130 on the new handset
press and hold the locator (find hs) button on the main base 5 seconds,
then press the OK button on the new handset, it will give a long beep to confirm it worked.
If you have any other questions, just let me know. Otherwise, please take a moment to rate my service using the stars at the top of the page; hopefully I have earned 5 Stars. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh and ask for Nathan.
Thank you, ***** ***** a nice day,
