The DISPLAY PWR SAVE softkey is used to switch on/off the power-save mode for

and is confirmed by ENTER.
• The power-save mode is deactivated by pressing the key again.
On leaving the menu with the power-save mode in the activated state, the softkey is

response time. Pressing again the key switches off the power-save mode.
