LCD Display Timeouts

All menus timeout to revert to the previous (higher) level after two minutes with no user activity. If logged on,
then after five minutes with no activity the user is logged off. Thus with no user activity the LCD display
always returns to the top-level display and logged off state.
The LCD backlight is under control of the processor. It is switched on whenever any button is pressed, and
stays on for five minutes after the last key press has occurred. Should a fault occur, the backlight is
automatically illuminated.
