There are two levels of user lockout available.
The first level locks the inputs so that the input source cannot be changed by pressing the input buttons on the LCD.

4) Backlight Timeout
The time the backlight remains on after the screen has been touched can be adjusted. The time can be adjusted between
0 and 600 seconds. Setting the time to zero keeps the backlight on continually. Set the time to 1 sec and the backlight
will turn off after 1 sec etc.
5) Calibrate Volume
This option has been made available in the event that the volume will not reach the full 100% maximum level or will not
reach the 0% minimum level. Small adjustments can be made which shift the volume scale up or down.
6) Change Zone (Wall plate ID)
Use this option to set the wall plate ID. This must be set to match the RJ45 port connection on the rear of the
A 4480B. E.g. if the wall plate is connected to port 1, the ID for the wall plate must be set to “1”.
