5.2 LCD & Keypad
5.2.1 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. This version of
software has the timeout period set to 5 minutes.
5.2.2 Status Icons
At the top of the LCD is a row of status icons.

5.2.3 Keypad Buttons
The four keypad buttons are used to navigate through the LCD screens. Their use varies depending upon
the current screen in view; however the key combinations listed below are constant for all screens.
Alt +
Pan display right
Alt - Pan display left
The display has been designed for a maximum of 24 characters per line even though the
actual LCD can only display 19 characters. In the case of the iRIS 320 this is limited to 12
characters.
Using the panning function allows additional text to be viewed. This is most useful when
viewing logged data samples, where the sample date and time information may be off the
screen when the display is fully left.
