How to fix Panasonic KX-TG6591C when I cannot hear a dial tone?
- DDaniel RhodesAug 27, 2025
If you cannot hear a dial tone, the base unit’s AC adaptor or telephone line cord may not be connected. Check the connections. You can also disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, contact our service personnel to have the unit repaired. If the working telephone does not operate properly, contact your service provider/ telephone company.
