Review: you must de-register a handset before adding new one - The product is essentially a good product. I have owned the base for about eight years. I have had to replace one handset and have added one handset, bringing the total number to six, the maximum capacity of my base. I couldn’t figure out how to add the new handset. The literature with the handset suggested texting a Help number. I did so. A technician called me back on my cell phone. He was wonderful and solved my problem in a few moments. The customer service at Panasonic is excellent. They responded quickly to my text and knew exactly what to do. The explanation was quite clear. The technician was very pleasant.
Review: Our third Panasonic cordless set in 20 years. - Our very first cordless telephone set was a Vteck with 2 handsets we bought in the 1990's, but when we moved to a larger house in 2000 & we wanted the largest set we could find we selected a Panasonic system with 4 cordless handsets because of ratings and price. We never experienced a problem with that very first Panasonic set. We updated that first set when the batteries wouldn't hold a charge and it was just cheaper to buy a new updated set. The next Panasonic cordless set had 5 hand pieces that held charges longer, had greater range into our yard and improved voice quality. That set eventually started dropping calls and wouldn't hold a charge so we updated to the brand new current five set system and even purchased an additional handset for another room for a maxium total of six handsets. Plus I also bought another three handset system for our basement. These phones work flawlessly and we especially enjoy the call block feature for permanently blocking robocalls. We're delighted that feature really works efficiently. We've set the system up so the telephone rings one time to let us know it blocked a number we set up with the call block button. We've told all our friends about it and they've been buying these cordless phones just for the wonderful call block feature. We enjoy using the handset to listen to the answering machine feature. We're considering syncing our smart phones with the base unit and have been playing with doing it with one of our phones. We've had good luck with Panasonic cordless phones over the years and will probably continue to buy them in the future. We also enjoy the included belt clips on the handsets and are surprised how few cordless manufacturers include belt clips with their cordless phones.

## Questions & Answers

**Q: I want to use 680S without any landline or any connection to voip etc. I just want to link it to my cell phone. so that when i come to home, i do not have to use my cell phone. all calls get directly transferred to this phone. is that possible ?**
A: It will work great for you.No landline or VOIP needed.Just connect via bluetooth once and it will hook up every time you come home.

**Q: How many handsets can work with one base phone.**
A: Without referencing the owners manual, I can safely say 6.  Though not for everyone, I love that 2 cellphones can be bluetooth linked to the base unit (charging) and incoming cell phone call can be answered with any cordless phone in the house.  The drawback is that text messages do not appear on the cordless handsets, only on the cell phone itself.

**Q: Can this hand set be mounted to a wall?**
A: Yes , but no screws in box.

**Q: Can this phone work without base?**
A: Main base? Of course not. Any cordless phone system will have at least one hardwired base station.

### ⭐⭐⭐⭐⭐ Compatible with older base
*by R***R on December 3, 2020*

I bought this handset hoping it will be compatible with an older KX-TG6511 base. I was not expecting much as older bases are not on the compatible list. However, it works perfectly. Following the instructions I turned on the handset and pressed "Locate" on the base unit for 5 seconds. The handset beeped and the service icon appeared. I charged the phone for 7 hours as instructed and all our contacts were copied to the new handset. There are a couple of new buttons on the new phone but they work too. Used KX-TG6500 series handsets are still available on Amazon but for about $4 more you can get a brand new upgraded handset. I deduce from my experience that this handset will probably work OK with any Panasonic DECT 6.0 base.
