Freezing screens
Valdstejnska and Uvoz - You have to hold the button for about 3 seconds
Klarov we have prowise screens but 2 types depend on age and for one type of screens we have 2 types of remotes because our excelent students are taking them home :)
On one there is written Freeze on the second type is written Display but both buttons are doing the same job
I think K1, K2, K3 and K4 at klarov have newer Prowise screens and different remote and to freeze you have to do the following
Option 1
Press the power button on the screen. If you press and hold this for three seconds, you will get a menu where you can choose between black screen or lock screen.
Option with the remote control.
Using the "Button 11" on the remote control, you can choose to black out or freeze the screen. Keep five fingers on the screen and click the cogwheel on the left or press the cogwheel on the remote control. Under 'General' in the section 'Remote control' you can select the function of this button
