I know that the F1, F2 & F3 determine which device you are connected too this Keyboard will connect to 3 different devices Try Pushing The F1 key Logitec does not give you much information to work with
Sorry, there was a problem. Please try again later.Same thing happened to me. I inadvertently hit one of the three white keys at top left of keyboard F1 F2 F3... In retracing my steps, I saw F2 blinking and came to this site and saw the comments above. Just guessing, but I must have pressed the F2 button when I tried to type a '2'?? I pressed the F1 and it started working again. I did not see anything about this in the Logitech set up info.
Sorry, there was a problem. Please try again later.JUST HIT F1 KEY
Sorry, there was a problem. Please try again later.When you turn it on press F1. F1 through F3 are used to connect up to 3 devices.
Sorry, there was a problem. Please try again later.I suggest trying to reprogram your K780 Keyboard to work with your desired connected device. Remember, you have to pair them first and the K780 has three (F1 thru F3) keys that allow you to interface to three different Bluetooth types devices. Could be that your desired connecting device is no longer paired and then make sure that the Flashing F3 key is paired for your desired device. If both are paired to each other, Then it should work if you have new batteries (they last longer the six moths usually). If this doesn't solve your problem return to reseller if under warranty.
Sorry, there was a problem. Please try again later.Hold down fn and p keys at the same time for 3 seconds. That should allow it to recognize the USB instead of Bluetooth.
