Changing a display name

I know you can change a display name, example would be changing a name from Net, to perhaps network.
I see it on the setup but the manual is unclear as to how to do it.

Hi transmaster,
What unit do you have? Thank you.

Sorry that would be important My unit is a TX-NR709

Hi transmaster,

This information is on page 41 in the manual,

The following is how to change the display:

Changing the Input Display

1 Press TV/CD, GAME or VCR/DVR.
“TV/CD”, “GAME” or “VCR/DVR” appears on the
display.
2 Press and hold down TV/CD, GAME or VCR/DVR
(about 3 seconds) to change the input display.
Repeat this step to select the desired input display.
Note
• DOCK can be selected for the TV/CD, GAME or
VCR/DVR input selector, but not at the same time.
TV/CD → DOCK→ TAPE
■TV/CD:
GAME ↔ DOCK ■GAME:
VCR/DVR ↔ DOCK ■VCR/DVR:

Thank you!

Hi transmaster,
