This is the procedure to view or change the number of bumps to
    Emergency Throw off for web wrap-up:

    This is the keyboard:
	________________________
	|     |     |     |     |
	| 000 |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |  0  |     |     |
	|_____|_____|_____|_____|

    a.  Press these two keys marked with 0's together, depressing
	the one marked 000 just slightly before the other one.

    b.  The top line of the display will show the Distance that the
	Print Head or Anilox Roll must be shoved back for the
	Positioning System to recognize the start of a Web wrap-up.
	The Distances are currently in discrete steps, corresponding
	to the clicks on the wheel:

		00.8 mils	0 Clicks from the lowest value possible
		02.4 mils	1 Clicks from the lowest value possible
		04.0 mils	2 Clicks from the lowest value possible
		05.6 mils	3 Clicks from the lowest value possible
		07.2 mils	4 Clicks from the lowest value possible

	to a max of 52.0 mils (51.22, actually, because of metric
	round-off).

	This corresponds to Stepper Motor Tumbles as follows:

		00.8 mils	1 Stepper Motor Tumble
		02.4 mils	2 Stepper Motor Tumbles
		04.0 mils	3 Stepper Motor Tumbles
		05.6 mils	4 Stepper Motor Tumbles
		07.2 mils	5 Stepper Motor Tumbles
		etc, etc

    c.	Rotate the hand encoder to adjust the number of bumps to
	Emergency Throw off for web wrap-up.  The number from the
	factory is the smallest possible, meaning that the Web
	push-back is quite sensitive.  You will probably want a
	higher number.  Your number should probably be in line with
	the thickness of the material you're running.  For really
	thin stuff, leave it at 00.8 mils. for 18 point board,
	I'd suggest trying 02.4 or 04.0 mils.

	Try the lowest number that works without falsely tripping the
	Emergency Throw off for web wrap-up.

    d.  To make the Positioning Sysem remember the new value, press
	the two keys marked with 0's together, depressing the one
	marked 000 just slightly before the other two:
	________________________
	|     |     |     |     |
	| 000 |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |     |     |     |
	|_____|_____|_____|_____|
	|     |     |     |     |
	|     |  0  |     |     |
	|_____|_____|_____|_____|

	Pressing any other key(s) will make the Positioning Sysem
	forget about any changes you attempted to make.  This is the
	way you view (and verify) the current value without making a
	change.

    e.	It's good practice to check your work by repeating steps a and
	d above, omitting changing any data.
