Normally the computer is marked off when not in use so a few instructions are needed to get it to take control of the telescope. Proceed as follows:
Look down list of devices and find FX16:. If it is OFF, type
MA FX16:,ON,,CD=ALL
and wait for the one line response, then type
GO JKT
and wait for the message LOADJKT: END OF TASK 0. If it says FX16:SYS type
GO JKT and wait for message, either LOADJKT:END OF TASK 0 or CONTROL SYSTEM is already running.
If this is the first startup after an end-change or reversing the telescope then GO JKT,F15E,COMPILE or F15W or F8E as appropriate.
JACOBUS KAPTEYN TELESCOPE
should appear followed by the user interface UI> prompt. You can then zeroset, input source positions, initialise T/S parameters or any other User Interface Command.
RESTART USER <cr>
The user interface (or other task) should now restart. If it doesn't then try again.
To switch back to engineering mode, just press the illuminated switch don't try to turn the key anticlockwise!
The telescope is now totally under the influence of commands entered at the USER terminal or the set/guide buttons either on the control console or the telescope handset.
