I have a panasonic KX-T7731 with a total of 10 phones.

I have tried to change the time on my panasonic a couple of different ways according to on-line help guides but still can't do it. This is what I have done:

1. hit program,0 and then the year, month, day, etc is displayed. I get to that point. After I type in the year, month day and day of the week, I get a beeping sound and it won't let me type in the new time.

2. pick up the phone and hit extension 11. It automatically defaults to my main line (#1) and doesn't do anything. I try to hit 77 but it really doesn't do anything but my number 1 extension is lit up.

3. hit program as described. I can't get past the first * without the beeping sound.

Each of these are done at my main administrator phone. I would appreciate any help.
