the local input button and volume controls. Once
hidden the local input icons will be greyed out.
They are no longer accessiible from the main
screen. To enable/show the local input press the
button and follow the prompts.

The pin number can be changed by pressing this
button and following the prompts.
3) Change Zone (Wall plate ID)

The time the backlight remains on after the
screen has been touched can be adjusted. The
time can be adjusted between 0 and 600
