You can select the desired ringer patterns of the base unit and cordless

handsets. 4 patterns are available for each line. Your phone comes from

the factory set to pattern 1. Programming must be carried out

separately for the base unit and cordless handset(s).

Make sure that the base unit/cordless handset is in the standby mode.

This sounds like a radio transmiting problem. This problem shows up first as "choppy transmit" where custimers complane of you sounding choppy or "under water". Google "KX-TGA400B choppy transmit" to find out more.

This is a very common problem with the KX-TGA400B and KX-TGA200B handsets. You need to replace the keypad or send it out for repair. Google "KX-TGA400B improved rubber keypad". Do not use the original factory keypad, the contacts are to small.

It sounds like the phone system base station is burned out.

Press the mute button to turn mute off.

I don't think that is possible on that model of phone. This is a phone with only the basic features and a fixed ringtone.
