2.5.2 LEDs
The 8525 G2/8530 G2 is equipped with four tri-coloured LEDs
located in the upper-right corner of the keyboard. If you have an
8530 G2 and are using the onscreen, soft keyboard, only the API and
Rx/Tx LEDs are available in the taskbar.
Important: You should proceed cautiously if a LED is illumi-
nated in red; this generally indicates an abnormal
operating condition or an active laser emission.
