ELIMINATOR V3.6

INSTRUCTIONS FOR OPERATION

The Portatree Eliminator has been designed to make reaction time practicing easy
and realistic. Many additional features including the ability to drive a full sized Portatree,
an RS-232 Serial Port to connect to a Large L.E.D. Display, and the ability to set up a
Starting Line have made the Eliminator the most versatile “Table Top” practice system
on the market. The features of operation have been simplified so that the user can make
changes to the system with a minimum amount of change to the initial set up program.

POWER UP

To turn on the Eliminator, push down the Rocker Switch on the top left side of the
unit. Every light on the Eliminator will be illuminated, then all segments on the LCD
Screen will display and lastly the version and the serial number of the particular unit that
you are using. The display will look like this: Version & Serial # 3.6 S.0000

After about 3 seconds, the unit will display: P r A C t I C E , the “r” and “t” do
not look correct, but they are.

NOTE: 7 segment displays do not properly show all of the alphabet characters - - A
combination of upper and lower case alphabet characters are used to indicate modes of
operation.

To begin, depress the START Switch and the Prestage Lights will come on.

The Eliminator will always start in a Full Tree, Dual User, and Automatic Reset
Mode on POWER UP. Depress and hold down the switches on the face of the
Eliminator which say “Stage Left” and “Stage Right” or plug in the external Hand
Switches and depress the buttons. Do not release the switch or button once you have
depressed it or the computer may red light you. Release the switch instantly when you
see the third amber light come on. Remember, when you see the light, not when you
think you see it. Great reaction times have to do with consistency, which translates into
lightning quick reflexes.

IMPORTANT*** External Hand Switches or the switch on the face of the
Eliminator can be used at any time. **** If the previous user has Left Delay in the
delay box, your results may not be what you expected. To check the delay box, at the
S UP S UP Prompt, depress Delay Box (Left or Right) and the Delay Number will
appear. Depress RESET to zero or UP or DOWN to adjust. **Depress the START

Switch to begin practicing again.**

HOW TO USE THE ELIMINATOR & OPTIMIZE YOUR

PRACTICE SESSIONS

When you see PrACtICE, Depress the Start Switch. The Eliminator will display:

S UP S UP (Stage UP Stage UP)

The S UP prompt means that you should stage up in that lane. When the S UP
prompt is displayed, the Eliminator will display the prestage lights in both lanes. When
you depress the Stage Switch on the face of the Eliminator, or depress the External Hand
Switch, the computer will acknowledge the signal and only the S will remain in that lane.
This indicates that the person in that lane is (staged) ready to practice. You must hold the
Stage Switch down and not release it until you reach the point in the tree sequence when
you want to measure your reaction time. Premature release of the Stage button may
result in an early RED LIGHT foul. You can play staging games, but if the computer
recognized that you are staged, you will red light.

The Eliminator also has three quick modes of change that can be instantly
obtained in the Practice Mode by depressing the selected switches on the face of the unit.
These changes are:

SINGLE/DUAL - - 1 OR 2 PLAYER // PRO/FULL - - TYPE OF TREE SEQUENCE

MANUAL/AUTOMATIC - - TYPE OF RESET

If you depress the SINGLE/DUAL Switch the Eliminator will display:
F A d or F A S. The “S” or “d” indicates Single User or Dual User. It will be displayed

for 2 seconds and then return back to practice. By continually depressing this switch, you
will cycle back and forth between the two modes.

The PRO/FULL Tree Switch works in the same manner. If you depress this
switch you will see: F A d or P A d. The “F” or “P” indicates whether you are in Full
or Pro Tree.

When the MANUAL/AUTO Reset Switch is depressed, you will see: F A d or
F L d. The “A” indicates automatic reset and the “L” indicates manual reset. Automatic
reset can be overridden any time by depressing the Reset Switch. This speeds up your
practice session. In Automatic Reset Mode, the Eliminator will wait 5 seconds before
resetting the computer for the next round. After 3 seconds of displaying the green or red
lights, the computer will automatically shut off the L.E.D.’S to preserve the batteries.
The L.C.D. Display will hold the results for 2 more seconds.

In Manual Mode, the L.E.D.’s will shut off after 2 seconds but the LCD Display
will retain the results until the Eliminator is manually reset.
