After changing the mode, press the set button (↳) to switch to the standby screen and operate the product normally.
Is it a malfunction that the display is continuously turned off?
It is not a product or functional malfunction, and it goes into power saving mode when there is no operation or use for 1 minute. If you press the set button (↳), the power save mode is released and the display is turned on. (You can check the user manual and manual video on our website for more details.)
