1. First use of machine
When using the Powershot 3 for the first ti e, there are so e parts to think of. So e parts need to
be installed in the achine and you should think about so e things before using the achine:
•First, you will find so e fuses with the achine, one of these need to be installed in the
achine panel. Disconnect the 220V cable! Then turn the fuse-holder to the left so you can
add the fuse into it and put back in the achine panel and turn to the right to lock in the
achine panel.
•The Re ote Control (RC) uses 2 pcs 1.5 V batteries which need to be installed in the RC.
Open the battery holder and install the batteries and close the holder.
•When you want to use the achine with the internal battery, it need to be fully charged first.
Use the charger by putting the power cable in a 220V connection and connect the other
round connector to the round connector of the achine panel. The achine could be turned
off when charging. The la p of the charger shows if the battery is still charging (red) or if it
is fully charged (blue). You can also hear the fan of the charger when charging. When the
achine is turned on, the display shows the percentage charged of the batteries but keep in
ind that a achine in standby shows a higher percentage when the achine is used.
•When the Re ote Control is “On”, the batteries will slowly be e pty, even though the RC
uses very low energy. That’s why it is better to turn off the RC, when you stop working with
the achine. To turn ON/OFF the RC, you should press the “Power button” for about 3
seconds, till you see the few arks on the RC display appear/disappear.
•When using the Powershot 3 with the battery, you should turn the “Power button” on the
achine panel to “DC”. When using the achine with a 220V cable connected to 220V and
to the flat connection of the achine panel, the “Power button” should be turned to “AC”.
When not using the achine, the Power button should be set in the iddle. When the power
is set right, the power la p, on the achine panel, will light.
•The ball bucket could be easily turned upside down by oving the flat hole of the ball
bucket over the handle so it easily fit on the ball achine. Then the ball bucket could be
filled with balls.
•As soon as the Power supply is set correctly, the power light on the control panel lights up
and the shooting wheels start to rotate but the achine does not start shooting. The re ote
control can be switched on by pressing the powerbutton on the re ote control for 3 seconds.
If the achine and re ote control are "On", do not stand in front of the achine. The
shooting wheels are started with a press of the "> / ||" button on the re ote control and the
achine start shooting the balls after 3 seconds (a safety for accidental pressing). Shooting
is stopped again (standby) by pressing the "> / ||" button again. If you want to only put the
achine into standby ode but do not yet use it and want first ake so e settings on the
re ote control or ake a progra , you can already set it on the re ote control. Only when
3

you start shooting ("> /" button), all new settings at the re ote control are sent to the
achine and the shooting is started (with a delay of 3 seconds).
•The front feet of the achine deter ine the angle of the achine itself. A s all change
higher / lower deter ines the exact depth of the different balls, these can be adjusted with a
wrench (nr 17) by the nuts on the inside of the achine (left and right of the shooting wheels
on the inside botto of the achine) holding the key and then turning the legs at the botto
by hand or using a hex key. For ore beginning players, who use the achine at a lower
speed, the legs will have to be set "longer" (higher) so that the balls will go over the net at a
lower speed, and for high level players these will have to be set shorter, so that the achine
shoots sharply over the net at high speed so that the balls are not shot into the fence at
axi u speed. It is not the intention to change the feet continuously but only a first /
single ti e to ake the achine suitable for the correct level of players. The correct depth
can also be adjusted by adjusting the speed. You can adjust the setting of the front feet only
if you have already played with the achine a few ti es and want to "finetune" the achine
for your level. You can also contact De Racketclub for questions about this.
•Another good way to deter ine the correct height of the forefeet is to set the achine
"rando ". The order is as follows:
1. Allow achine to shoot in "rando ode".
2. Check whether the achine shoots balls into the net. If, after speeding up, balls still get in
the net, put forefeet longer (higher).
3. Check whether the achine shoots balls behind the baseline. If this is the case, set the
speed lower or set top spin.
•The right position of the achine horizontally could be deter ined by:
1. Set the achine on the baseline in the horizontal iddle
2. Set the achine to F (fixed position) and the horizontal position to “40” ( iddle) with the
arrows.
3. The achine should now shoot in the horizontal iddle of the court (direction of the service
line between the 2 service fields).

2. Speed, Frequency, Topspin and Slice balls
All exercises, in the achine, can be adjusted by speed. Just like a tennis player, topspin or
backspin (slice) can also be given to the ball. With ore topspin to the ball, the balls will bounce
shorter behind the net, with ore slice the balls will get deeper and with ore speed the balls will
also get deeper. When changing the speed, the top spin or slice is stopped. The speed can’t be ixed
with spin. When setting the topspin or slice, the speed of the 2 different shooting wheels are a fixed
value “around” 80k /h. With topspin or slice, the depth of the ball should be changed by setting the
height. The height, a ount of topspin and backspin influence the height / depth of the ball. The
a ount of wind can also influence the direction and depth of the ball, you have to adjust it yourself
or you can put the ball cannon in the field shorter / deeper. The ball achine nor ally is positioned
on the baseline on the other side of the net of the player.
The frequency deter ines the pause between each shot ball, it can be set between 1 (long pause)
and 9 (short break, balls very quickly in succession).
The frequency also plays a role in the horizontal and vertical ove ent. The achine continuously
oves right / left with horizontal variation. The frequency then deter ines when the ball is actually
shot. This can have a lot of influence on the weight of the exercise. So eti es the achine is
oving left/right to the other side but not shooting the ball because the frequency is set low.

3. The functions of the machine
The achine has any different functions that allow the balls to be shot in different ways:
•With different speed
•With different frequency
•With different effect (topspin or slice)
•At different locations:
1. 1 fixed point (F)
2. At different depths ("high / low")
3. Horizontal on 2-line or 3-line (2 or 3 fixed positions) and vertical in 2 different distances
(short or deep)
4. Rando , the balls are rando ly shot at 28 different positions.
5. Cross, here 6 different co binations of 2 cross balls (1 bal short, 1 deep and at 2 horizontal
positions)
6. By your own progra of up to 28 positions
6

1. Fi ed point
The ball can be set at a fixed horizontal and vertical position on the court. This position can be set
horizontally via the "<" and ">" buttons on the re ote control between position 10 (left for the
player) and 70 (right for the player). The vertical position can be set via the "^" and "v" buttons
between position 10 (low) and 40 (lobs).
→ Note that a preferable speed and spin can be co bined with the fixed point
→ Once the altitude is set to 20 or higher, the speed can only be set to 50 or lower. This is a security
that the balls are not accidentally shot over the fence.

2. Horizontal and vertical movement
The Powershot 3 has several ways to vary horizontally:
•Rando between the 2 “tra rails”
•2 line function (on 2 fixed positions left and right)
•3 line function (on 3 fixed positions left, iddle and right)
The Powershot 3 can vary vertically in 2 ways:
•Rando between 2 depths (eg serviceline and baseline)
•At 2 fixed positions short and long (eg serviceline and baseline)
The variations can not be co bined with each other, for this is the "rando function". However, the
vertical variation can be set to a fixed horizontal position, for exa ple on the forehand or the
backhand, via the "<" and ">" buttons.
Horizontal variation, press the "horizontal" button each ti e:
•Rando between the 2 tra rails (re ote control shows: ………….)
→ The ball is played rando ly across the entire width of the field. The frequency setting has
a big influence on the weight of this exercise. If the achine always oves to the other side
but only shoots again when it is back to the player, it is easier than the achine just shoots
when it is positioned towards the other tra rails.
The height of the horizontal balls can be adjusted as desired (depth) with the vertical buttons
"^" and "v".
•2-line wide (re ote control shows: “. .” )
→ The 2-line wide is often used for training of 2 (groups) players. Group1 gets 1 ball and then
shoots the achine to group2, leaving group1 ti e to prepare for the next stroke or to join the
back of the row again
•2-line iddle (re ote control shows: “. .” )
•2-line narrow (re ote control shows: “. .”)
→ The 2-line narrow shoots at 2 positions close together so that it is suitable for 1 player resp.
forehand, backhand, forehand, etc.
•3-line (re ote control shows: “. . .” )
→ the iddle position gets ore balls than the left / right positions, aking the 3-line function
ore suitable for 1 player who gets the balls in a fixed pattern over the entire court
8

Vertical variation, press the "vertical" button each ti e:
•Rando (about 4 degrees in height difference), the ball is rando ly shot between the short
and long position (re ote control shows several points above each other)
•2-line (about 4 degrees in height difference), the ball is shot short and long (re ote control
shows: “:” )
During the vertical variation, the horizontal position can be set at a fixed horizontal point with "<"
and ">".
To turn off the variation, press the "F" button.
→ Note that speed and spin can be co bined with the different variations according to your own
insight.

3. Random balls
The achine can shoot the balls at 28 rando positions in the field, 7 (horizontal) x 4 (vertical)
positions.
As soon as the "Rando " button is pressed, the achine will ove between these 28 positions. The
achine has a unique rando function, not just left/right and up/down ove ent but real rando !
The speed of the frequency, for the o ent of shooting the ball, is of great i portance here.
So eti es the balls are shot at the sa e position a nu ber of ti es, but then it is purely
coincidental because the achine has already oved to different positions on the court but has not
shot there because of the frequency setting.
Rando function:
1. Press "Rando "
To switch off the rando function, press the "F" button.
→ Note that speed and spin can be co bined with the variations as you like, the position is fixed.
→ If the speed is very low, the achine ay have to be oved closer to the net. The height over the
net can not be changed at "Rando ", so if this would be necessary for children, this should be done
by anually set the front feet of the achine a bit higher.

4. Cross balls
The achine can play two balls in a cross (diagonally) in two different places. There are 6 different
co binations, the nu ber of ti es the "Cross" button stands for each co bination:
1. Right short, Left deep *)
2. Left short, Middle deep
3. Middle short, Right deep
4. Right short, Middle deep
5. Middle short, Left deep
6. Left short, Right deep
To stop the cross exercises, the "F" ust be pressed.
*) The starting order of these trainings could differ, dependant on what training last ti e stopped.

4. Programming
With the Powershot 3 you can create your own progra . One progra could be ade after the
re ote control is turned on, and it couldn’t be saved. As long as the re ote control is on, the
progra is still there, even when you oved in between to other trainings. There are 28 positions on
the court (7 horizontal and 4 vertical). Each position can be used once, which eans that a
axi u of 28 positions can be progra ed in a progra .
To start progra ing, press the "Progra On" button for 3 seconds until a flashing dot appears on
the screen. The desired position can then be selected with the 4 arrow keys. Every position is saved
when pressing "Progra On", an already progra ed position is deleted with "Progra Off" (go
first to the position to be deleted). To start a new progra (delete old progra ), press the "Progra
Off" button for 3 seconds.
The speed, frequency and spin can be adjusted as desired for the progra . Because the 28 positions
on the court are fixed, the front feet of the achine ay need to be adjusted once at the correct
height. This is only necessary if the achine, in case of short balls, shoots into the net or in case of
long balls, outside the baseline.
The progra is ade fro the position of the player (left is left on tennis court and right is right on
tennis court), however the short balls are at the botto of the screen and the deep balls above. This
takes so e ti e of getting used to and it is good to "play with" here.
Sequence of progra ing:
1. Progra On (3 sec): Start progra ing
2. Progra Off (3 sec): Delete previous progra
3. Use the arrow keys to ove to the desired position
4. Progra On: store position in progra
5. Repeat 3-4 until the progra is co plete
6. Start shooting (>||)
→ Inserting a position into an existing progra is difficult. The progra ay have to be executed
and stopped at the o ent where an extra position needs to be inserted. Then add position. We are
still figuring this out. It is easier to create a new progra (see sequence above).
