There are two options of power saver function
(Dim Mode). The screen may be switch off (Screen Off)
or dimmed with different levels (Level 1, 2 or 3). In the
case when any of these options is set, after a delay, set
by parameters Dim Delay, from pressing any key the
screen is dimmed or switched off. After it has happened,
pressing any key will cause the display to switch on
again.
If Dim Mode is Off the screen will stay bright all the time.
By default, Dim Mode is of Level 2 (medium dim).
The power saver delay defines the delay period from last use of any key to the
start of the power saver mode. This delay period can be set for active Dim Mode
from 5s to 60m.
