LCD Operation
The iRIS LCD is controlled to optimise power consumption. If the display has powered down (in full power save mode), the
unit is in the lowest power mode and can be woken by pressing any key on 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. The timeout period is user configurable
