Why can't I hear a dial tone on my Panasonic KX-TG5421 Cordless Telephone?
If you cannot hear a dial tone on your Panasonic Cordless Telephone, confirm that the telephone line cord is connected.

If the handset does not ring, the ringer volume may be turned off. Adjust it.
Why can't I program items on my Panasonic KX-TG5421 Cordless Telephone?
If you cannot program items on your Panasonic Cordless Telephone, it may be because programming is not possible while the handset is being used. Also, do not pause for over 1 minute while programming. Try moving closer to the base unit.
