Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phone system.
To help you with this issue, may I ask:1) The Make & Model Number of the phone system you are working with? That model should be printed on a sticker on the bottom or back of the main base unit and START with KX-TG.2) How many TOTAL cordless handsets do you have with this system?
Can you read me the NUMBERS immediately after the KX-TG - from the MAIN BASE UNIT?
I only ask because the PNLC numbers are usually for a POWER ADAPTER - that connects to the main base OR the remote handset chargers.
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
