Hand set displays "check tel line"

Customer Question

hand set displays "check tel line"

Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

Expert:  Nathan replied 1 year ago.

Can you tell me a bit more about the problem please:

1) If you have multiple handsets (within the same system), does this happen with all of them?
2) Are there other phones or even a fax, outside of this system but on the same line? If so are they working properly?
3) Is this a landline from the local phone/cable company, or a VOIP service (vonage/magicjack/etc)?
4) Do you have dsl service on the same line?
5) Full model of the phone(s) (printed on sticker on the base usually)

These are not all yes or no questions, can you please give me detailed specific answers for each (#3) and the model of the base station (not handset)?

Great, thank you.

This symptom can indicate either a problem with the line (phone company equipment or the wiring in your home) OR a hardware failure in the base station (since the issue happens with all handsets). We most often see this type of damage to the base unit as the result of a power surge, either through the phone or power lines.

If possible it would be most helpful if you could test another device on the line, like a regular corded/wall phone. If you cannot right now we can skip that, but it may be necessary later.

The one thing you may attempt yourself is to fully reset the system:
1) unplug both power and phone lines from the main base.
2) remove batteries from all handsets
3) wait at least 15 minutes, then restore all
4) place a handset on the main base for a minute, as if to charge
5) check for functionality.

Let me know the results.

sk gotta go key you later
Expert:  Nathan replied 1 year ago.

Thank you for trying. The next step would be to check another phone to test the line.

Can you get/buy/borrow a basic corded phone, plug it into the wall jack used by the panasonic base currently, and let me know if you can get a dial tone on it?
