Press Start (you will hear the wheels start spinning) and balls will begin loading into the machine. After
a few seconds, the first ball will reach the top of the Ball Tube. Press Stop to halt ball feed.
Grab your racket and prepare to return balls from your robot. The first balls that are thrown will be
Basic Balls and should be delivered along the centerline. Press Start and observe where the balls land
in relation to the centerline. If balls are delivered either left or right of the centerline, then stop ball
delivery. At the robot, loosen the large Black Knob on the rear of the Ball Tube (see Photo 7) and rotate
the head in the direction necessary for balls to land closer to the centerline. Repeat until all balls are
landing close to the centerline, then press Stop.
One Ball Type Thrown To One Placement
The easiest way to learn the various controls is to start with a single ball type delivered to one location.
Please remember that only the Current Ball (indicated by a flashing Ball LED) can be changed. Upon
powering on the Control Panel, only the Ball 1 LED should be lit and it should be flashing. If any other
Ball LED is lit, hold down its corresponding Ball Button until its LED becomes unlit.
To adjust Ball Type:
•
The Trajectory Buttons raise (3) or lower (4) the ball trajectory (throw angle).
One short push chang-
es 1 unit (about 0.5°) of the throw angle (fine adjustment). Each Trajectory LED represents 7 units
of adjustment if a single LED is lit and 9 units if 2 LEDs are lit. The exceptions are the 5 and –5 LEDs,
which represent 16 and 8 units respectively. Altogether there are 154 units of Trajectory adjustment.
If you hold down a Trajectory Button, the stepping action is accelerated and you rapidly change the
setting.
•
The Sidespin Buttons (7 & 8) change the orientation of the sidespin on the ball.
The zero setting
means there is no sidespin on the ball. Each button press from zero represents a 15° change in
orientation, except for the first press, which is 30°. Settings to the right of zero are degrees of right
sidespin and settings to the left are degrees of left sidespin.
•
The Speed Buttons reduce (9) or increase (10) the speed of the ball.
There are 21 increments of
speed adjustment.
•
The Spin Buttons reduce (11) or increase (12) the amount of spin on the ball.
A setting of zero indi-
cates no spin (dead ball). Settings to the right of zero (1 to 6) indicate stronger and stronger amounts
of topspin. Settings to the left of zero (-1 to -4) indicate stronger and stronger amounts of backspin.
To adjust Ball Placement (also called place or location):
•
The Placement Buttons (5 & 6) determine the left to right landing spot of the ball.
The zero position
corresponds with the centerline of the table. The 1 to 9 settings correspond with balls progressively
landing closer and closer to the right corner of the table. The -1 to -9 settings correspond to balls
landing progressively closer and closer to the left corner.
To adjust Ball Frequency:
•
The Ball/Min Buttons decrease (13) or increase (14) the rate, or frequency, of shots.
When either
button is pressed, the frequency, in balls per minute, is shown on the display. You can select settings
from 1 to 100 balls/min.
