sorry for newbie question do u have to insert the sd card with the test mode every time u wanna get into test mode. when i inserted the card everything was copying then screen froze on that green and white screen can someone explain. im trying to get into test mod so i can make a backup of everything. o yea i inserted the card 3 time and all the time it said copying does this mean i have 3 copies now on my system

when that green screen pops up look at the upper right there should be an x just click it u should be good to go. and there's no copy's of anything on ur sd or on the unit if u haven't actually done anything, test mode is not an installation just boot files.

okay i see the x i tried clicking it but it wont click out i tried calibrating but i just cant touch that x do i need to use the little pen that came with the f90 maybe my fingers to big?

Yes best to calibrate screen first.....then boot off SD card into test mode.

When you see the green box in middle of the screen, use the stylus pen and click on the 'x' in the top right corner and you'll be good to go.

Then use the stylus for all the actions of what you're trying to do, etc

this is how it all worked for me without issue
