I’ve tried pressing the bottom button on the right side of the EFIS (RNGE button) and hold down for more than 1 second to get a screen shot to save to the SD Card inserted into the top of the EFIS. When I do that I see “Saving screenshot 1, 2, etc”. I always see this message on the left side of the EFIS that it is saving the screenshot. Occasionally it works but most of the time it doesn’t. I have tried multiple 8GB SD cards and have tried reformatting each before using. I verified that the SD card is not locked. Another way that does work is: SET-LOGS-SCREENSHOT but that is 3 button pushes vs 1. This also shows “Saving screenshot” on the left side of the EFIS.
Do I have to go to the Admin settings-Transfer files and make sure that SD Card is selected instead of USB? I use USB to update the EFIS maps and software updates so maybe this is the default I last selected??
