SST Function keys

Keys F3, F5, F10, F12, and F16 usually have the following functions:

• F3 key ends the SST function.
• F5 key causes the system to ignore input to the display. Use this key to see the same display with the input erased or a waiting display.
• F10 key causes the command entry display to be shown. You can then enter CL commands.
• F12 key causes a return to the previous display. You can use this key to return through the prompts to the first service tool display that has an option that can cancel the service tool.
• F16 key always returns control to the System Service Tools (SST) display; it does not cancel the active service tool.
