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.

The labels used on the Input buttons on the A 4433 can be user defined to any text description to a maximum of 12

button will automatically import the labels from the configuration files found on the Micro SD card. See section 5.3 for
more details.

• BACKLIGHT TOGGLE - the LCD backlight will toggle OFF and ON for each button press.
Each of these can be turned ON or OFF independently via this menu function.
