I have an 824 at a customer and have the CPC-S 3.0 and CPC-M 3.2 manual. Per the features manual I should be able to:

1. On/Off

2. Prog

3. #2

4. Port No.

to change name on the port.

Manual says to use "Auto" to backspace and "Conf" to switch between numbers and letters.

However "Auto" does not backspace but enters uppercase "A" and "Conf" does not switch cases but enters uppercase "C".

I assume this is a software version problem and do not know how to resolve this. Customer need names at the extensions, so I am trying to resolve this. I understand that Pansonic is no longer supporting 824 so need help on this. Customer does not have money to upgrade system now.
