The S520 keyboard does not indicate the state of the Number (Num) lock and Capital (Caps) lock keys on the keyboard. Logitech uses on-screen Caps and Num Lock indicators. These messages will appear for approximately 2 seconds each time either key is pressed.
In addition the USB receiver has an LED for Num lock and Caps lock indicator when they are enabled.
NOTE: This feature requires that Logitech's Mouse and Keyboard software (SetPoint) be installed on your computer..
