	Please try these things in this order.

	1) Try CTRL C followed by A and Enter. This will abort any command that may have hung up

	2) Press RESET on small monitor keyboard.

	3) Follow this sequence:
	* a) Pull out upper keyboard.
	* b) Hit “Scroll Lock” button twice followed by the number 2.
	This switches the upper monitor from the smart-set computer to the PC control computer. Try a second time if this doesn’t work. You should see a black screen with “Ready” near the top or you will see a menu driven screen. If the monitor switching does not work, go up to the gray interface box on top of the stepper control rack. Press the gray flash button. This is located in the area where the cables all plug in.
	* c) Push in upper keyboard.
	* d) Lift up plastic flap over lower keyboard and press break
	* e) Turn off lower monitor by pulling out the monitor box and using the switch on the top right front corner of the box (DO NOT TURN OFF SYSTEM POWER SWITCH ON MONITOR! This will shut down the whole system)
	* f) Wait 1 minute and turn the monitor back on.
	* g) Let monitor warm up until you see a cursor on the screen.
	* h) Hit the Set Up key on the stepper keyboard (lower keyboard)
	* i) Hit Line/Local key (number 4) so that the on-line LED lights.
	* j) Hit the Set Up key again. You should have a cursor on the screen.
	* k) Pull out upper keyboard and press the Alt button and “O” at the same time.
	* l) Hit Return to start the program.
	* m) Push in upper keyboard.
	* n) At the prompt on the lower monitor, enter the time and date as specified (10:25 19-NOV-02)
	* o) Stepper will finish booting up.
	* p) Pull out upper keyboard and hit “Scroll Lock” button twice followed by the number 1 to transfer monitor back to the smart-set computer. Try a couple times if this does not work and use the flash button (see instruction b) if needed.
	* q) You are ready to Log In.
	4) Follow this sequence:

	a) Follow system shut down sequence, but DO NOT TURN OFF LAMP OR ENVIRONMENTAL UNIT

	b) Wait 5 minutes.

	c) Follow system start-up sequence except for instructions on lamp or environmental unit.
