When screen gesture mode is enabled, a frame indicating the screen gesture active area is displayed. 
This frame is displayed with a bright red line only when the contents within the screen gesture active area are not enlarged, and with a combination of bright red and dark red lines when the contents are enlarged. You can check that screen gesture mode is enabled when this frame is displayed. 

* For the GOT3000 series, only models with a capacitive-type touch panel are compatible with screen gesture mode.
