Red Light Won't Go Off

1. Press the "Message" button on your Panasonic KX-NT680 phone.

2. If that doesn't work, try pressing the "Intercom" or "Clear" button to clear any message indicators.

3. If the light still doesn't go off, you may need to perform a full system reboot on your phone. To do this, unplug the power cord from the phone, wait for a few minutes, and then plug it back in. This should reset the phone and hopefully resolve the issue.

If none of these steps work, there may be an internal hardware or software issue with your phone. In that case, I would recommend reaching out to the Panasonic customer support for further assistance. They will be able to provide you with more specific guidance for your model of phone.

The phone is not plugged in. Make sure that the phone is plugged into an outlet and that the power cord is properly connected.

The battery is low. If the battery is low, the red light will stay on to indicate that the phone needs to be charged.

The phone is in a power saving mode. Some phones have a power saving mode that will turn on the red light when the battery is low. To turn off power saving mode, check your phone's settings.

The phone is in a call. When you are on a call, the red light will stay on to indicate that you are currently in a conversation.

The phone is receiving a call. If you are not currently on a call, but the red light is still on, it may be because you are receiving a call.

There is a problem with the phone. If you have checked all of the above and the red light is still on, there may be a problem with the phone itself. In this case, you will need to contact Panasonic customer support for help.

Here are some troubleshooting steps you can try if the red light on your Panasonic KX-NT680 phone won't go off:

Check that the phone is plugged in and that the power cord is properly connected.

Check the battery level. If the battery is low, charge the phone.

Check your phone's settings to see if power saving mode is enabled. If it is, disable power saving mode.

If you are on a call, end the call.

If you are receiving a call, answer the call or decline the call.

If you have checked all of the above and the red light is still on, contact Panasonic customer support for help.
