Daily operation
4.1 Keyboard activation/deactivation
To activate the keyboard:
In order to avoid unwanted or accidental activation of the OSD keyboard, a lock/unlock mechanism has been
implemented. This means that, before the OSD keyboard can be used to change any of the setting of the
display, it needs to be unlocked. Two options are available to activate the keyboard:
1.
Option 1: Swipe a finger from the power button zone to the left for about 12 cm.
2.
Option 2: Press the Power On/Off key for 3 seconds and release it within the next 2 seconds.
As a result, the keys will light up and are now available for further actions. However, if no further actions are
taken within the following 10 seconds, the key indicator lights will dim and will be locked again.
To deactivate the keyboard:
The keyboard will automatically lock after 10 seconds of inactivity, except while navigating the OSD menu,
during which it remains unlocked.
As a result, its backlight switches off to indicate that the keyboard is locked.
Keyboard backlight 'Always on' mode
When used with keyboard Backlight 'Always on' (factory setting is 'On with touch'), the lock / unlock status of
the keyboard cannot be linked to the on / off status of the keyboard backlight (the backlight is always on in this
mode, except when in Power Save of Soft Off).
Therefore, the keyboard lock status is being signaled by a slow blinking of the keyboard backlight between on
and off at a rate of one cycle per second. The Keyboard will automatically lock after 10 minutes.

About the keyboard backlight
By default only the stand-by key is visible. After keyboard activation (see "Keyboard activation/deactivation",
page 32), the backlight of all keys is switched on for a few seconds. When you touch any of these keys again
while the backlight is on, the function of the key is executed. If no further action is taken within the time-out, the
keyboard backlight is switched off again.
The keyboard backlight auto-dim function can be disabled in the OSD menu so that the keyboard
backlight is always on (Keyboard Backlight).
