I just received my new hotspot Saturday and I am attempting to learn and navigate the various screens. I’m having trouble determining how the screensaver page works. I have turned the screen saver page on. I have adjusted the dim level to a minimum by sliding the adjusting bar all the way to the left. I’m not at all sure what the 5  + or -20 buttons actually do. I am hoping that they represent a timer when the screen would hibernate. Is this correct? I have not been able to get it to work yet. Please advise how I get the screen to hibernate between my morning and afternoon session or do I have to turn the unit on and off manually to save the screen? Thanks PaulP WA4AA
