  • Support is great
Style: Optional Additional Handset
Handset worked great after getting advice from the Panasonic consultant on how to disconnect the old handset (one of six) that wasn't ringing correctly after five years. Clay was very quick, responsive, professional and helpful. Total time on the phone was only a few minutes and everything was operational. The whole set has been very handy. ... show more

  • Nice phone system
Style: Optional Additional Handset
Easy to program. Sound quality good. Occasionally calls come through as faxes when they are not. Did not have this problem with set they replaced. I have 6 handsets on this base. Lightweight. Reasonably priced. Don’t have to use a phone battery. Can’t do three way calling which I miss. Long battery life. ... show more

  • Easy Setup and Perfect Compatibility
Style: Optional Additional Handset
The Panasonic Additional Cordless Phone Handset worked perfectly with my existing KX-TGF540 phone system. It was extremely easy to set up and integrate into my current setup. The sound quality is clear, and the handset is just as reliable as the main phone. It’s a great addition for anyone looking to expand their cordless phone system with minimal effort. Highly recommend this accessory for seamless compatibility and ease of use. ... show more

  • Integrated successfully into our existing phone system
Style: Optional Additional Handset
We bought this unit because in our existing Panasonic KX-TGF540 system with four phones, one phone's headset port failed and one base failed to charge after a couple of years of use. We used the purchased phone to replace the phone with the failed headset port seated in the base unit and the purchased base to replace the failed base (which seems to have failed because we unknowingly spilled some liquid into it, which wasn't cleaned up). Both devices have been working fine for a few weeks. We disposed of the failed base unit and use the phone with only the failed headset port as a floater, a fifth phone in a four-base system. To keep it charged, we alternate the fifth phone with another phone in one of the charging bases every few days. We had retained our Panasonic operating instructions, but we could have programmed the purchased phone into our system with the instructions provided by the seller, which I verified were accurate and well written. The product arrived timely and well packaged. The product description and compatibility were as advertised. ... show more

  • WORTH THE PURCHASE
Style: Optional Additional Handset
A quick delivery and a helpful enclosure make this an easy transition. The additional contact number if needed for additional help is a nice touch. My suggestion is to include following in the informational enclosure: charge fully - go to settings - register phone.

  • How to get help
Style: Optional Additional Handset
I have four phones which work fine, but the two new same phones I just bought would not function correctly, and I could not get help from Panasonic or other sources. The Panasonic company did not answer and the new phones I bought just show "Main Unit No Power" and then they stop. I need a source of guidance, or I just just send these back to Amazon, and not buy from Panasonic again. Fortunately I have my four phones. And I wish Amazon could help me with Panasonic. ... show more
