2.5.1.3 Cleaning Display ( CLEAN MODE )
The purpose of CLEAN MODE is to clean the surface of the display unit without accidentally activating a function. When
the CLEAN MODE is started, the touch screen will be deactivated for 60 seconds. Within this period the instrument
will remain functional, but it is not operable. Except when an alarm is activated, then the touch screen will be activated
immediately and the instrument will be operable again.
Figure 23: Clean Screen Menu
To start CLEAN MODE, perform the following actions:
1. Touch the CLEAN MODE button in the MENU.
The CLEAN SCREEN screen appears, see Figure 23: Clean Screen Menu on page 32.
2. Touch the CONFIRM CLEANING THE SCREEN button to start the CLEAN MODE.
The AlphaLine instrument switches to the CLEAN MODE COUNTDOWN page and starts the countdown sequence,
see for example Figure 24: Clean mode Countdown (Example) on page 32.
Note For safety reason, if an alert is active and needs attention of the operator, CLEAN MODE can not be
started.
The touch screen is now deactivated and surface can be cleaned. After 60 seconds, or at an active alert, the instrument
will become operable again.
