4.3.1 LCD Operation
The iRIS LCD is controlled to optimise power consumption. If the display has powered down, the unit is in a lower power
mode and can be woken by using the keypad.
After a certain period of no key presses, the display and backlight will power down again, although other functions
continue normally. If the user was logged on (PIN entered), they will be logged off. This version of software has the
timeout period set to 60 seconds.
