Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:1) The Make & Model Number of the phone system you are working with?
2) What phone service provider (phone company) you have for this phone line?
Hi again and thanks for that information.
The "kx-tga470" is the model of a handset, so can you please find the MAIN base unit of the system and send the model of that (usually printed on a label on the bottom of the base).
That looks like a part number for an AC power adapter.
The MAIN BASE UNIT is a LARGE "base" that is connected to the phone cord and an AC adapter.
Please look for that main base unit and see if you can find a Model there? It should START with KX-TG, and then be followed by 3 or 4 numbers.
I have attached a diagram of some example systems, showing the main components, to help you find the MAIN base unit.
Note: You may have to click the file name to see the diagram.
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)
