The US displayed on the bottom right is to
remind you which ThinkPad Keyboard Language is currently set, US stands
for US English QWERTY, this is important when displaying recovered SVP
as the letters can change depending on the Keyboard.
Diagnostics is the last option on the
Main Menu, if you press Down once more, the Main Menu is repeated again
from the first option
As you scroll through the Main Menu
Options, if you wish to perform the currently displayed selection, you
move the joystick tip to the Right
For example, you have scrolled Down through
the main menu to LSI
You wish to perform an LSI operation - you
move the joystick tip to the Right
If you now move the joystick tip Down
once more, you will scroll through the next of the 2 options available in
the LSI menu
With SVP Clear displayed if you move the
Joystick tip to the Right you select that operation
If you confirm that you do indeed wish to
Clear SVP by moving the Joystick tip to the Right the Clear SVP
operation starts
Had you moved the Joystick tip in any
direction other than to the Right to confirm it, the operation is
aborted
When the SVP has been cleared you see this, which is to
remind you to go into BIOS Setup, select defaults F9 and save F10
All of the LCD - Joystick operations
also appear on your PC or Laptop screen if you are running your terminal
Software
Notice "Joystick active" is
displayed on the PC screen followed by the operations performed using
the LCD - Joystick
Also note the more complete message
following the operation
You can switch back and forth at any time
between the PC keyboard running your Terminal Software or using the LCD-
joystick
If the LCD- Joystick was last operated and
you wish to use the PC keyboard just press 0 [zero] and you have control,
photo below, 0 was pressed screen at Main Menu
If the last command was type on the PC
keyboard and you wish to switch over to the LCD - Joystick, simply move
the Joystick tip either Left or Up and you are back at the
Main display on the LCD with the Joystick in control
Trying to explain using the LCD - Joystick
in fact makes it appear to be much more difficult than it is to use it in
practice.

options at that Menu level.
Right selects/confirms that menu
level or operation.
Left gets you out of almost
anything.
