Also the "Error" display, however, only at standstill of the flywheel. If you lea-
ve the recovery function, the previously set performance is adjusted again.

9.0 Switching between speed-independent / speed-
dependent operation (Countup/Countdown)
At the start, the ERGORACER always operates independent of speed. The
user can switch between speed-independent and speed-dependent operati-
on during training with the ‚SET' key. If both direction arrows are shown,
speed-dependent operation is selected. Pressing the ‚SET' key again returns
to speed-independent operation. If training is interrupted, the display com-
puter automatically switches back to speed-independent operation.
There is no limit up or down on power in speed-dependent operation. If
speed-independent operation is selected at a power of more than 600 W,
the power display is set at 600 W. and braking torque is altered appro-
priately. If speed-independent operation is selected at a power display
less than 25 W., power is set at 25 W and braking
Speed-dependent operation is only available during training
(Countup, Countdown) and is activated by the ‚SET' key. If speed-de-
pendent operation is selected, the braking torque remains constant. The dis-
played power does not alter until pedal speed is altered. When speed is al-
tered, the instantaneous power is calculated from the (constant) braking tor-
que and the actual pedal speed and is displayed correspondingly. If the po-
wer displayed in speed-independent operation cannot be adjusted (arrow
symbols are superimposed), the actual power value is displayed at the point
of switching over. Power can be altered using the ‚+' and ‚-‚ keys or speed.
During training, the displayed power is increased or decreased using the‚+'
and ‚-‚ keys, in 5 W (or 25 W) steps. The instantaneous power is used as a
measure for this. The new braking torque is calculated and set. Subse-
quently, the braking torque is kept constant and the power display is re-cal-
culated as described above when pedal speed changes.
It is only possible to alter the Ergometer power using the‚+' and ‚-‚ keys in
the range from 25 W to 600 W. If one of the keys is pressed outside this
range, the display jumps to the next possible value within the defined limits
and the braking torque is altered appropriately.
10 General
Braking behaviour
The electromagnetic eddy current brake produces the braking effect inde-
pendent from the speed such that the braking power is kept constant in a
wide range of pedal rotations (RPM).
Arrow display:
Performance range of the ergometer.
If the adjusted performance cannot be achieved with the current pedal ro-
tation (e.g. 400 Watt at 50 RPM - outside the grey range), an appropriate
arrow of direction (a) is displayed next to the current pedal speed (2).
The above diagram is only used to illustrate a performance range. If a per-
formance cannot be achieved with the current pedal rotation, an arrow
pointing upwards or an arrow pointing downwards appears for an in-
crease or a reduction of speed.
Velocity calculation
60 pedal rotations result in a velocity of 21,3 km/h.
Kilojoule calculation
The performance is entered in Watt (current performance) and the time in
seconds. Factor 4 results from the efficiency degree of a human being of
approx. 25% when training with the trainer. However, this is only a clue.
kJ = performance x time x 4

Fitness value calculation
The computer calculates and assesses the difference between the strain
pulse at training end and the recovery pulse after 60 s and the resulting
"fitness value" according to the following formula:
[
Value (F) = 6 - 10 x (P1 - P2)
P1
P1 = Strain pulse
P2 = Recovery pulse
Value 1 = very good
The comparison of strain and recovery pulse is a simple and fast possibi-
lity to control your physical fitness. The fitness value is an orientation va-
lue for your recoverability after physical strain. Before you press the re-
covery key (8) and establish your fitness value, you should train for a lon-
ger period, i.e. for at least 10 minutes, in your strain range. With a re-
gular cardiovascular training you will note that your "fitness value" im-
proves.
Average value calculation
For the average value calculation of pedal rotations, velocity, performan-
ce and pulse all training intervals are taken into account until the "Tem-
perature" display appears.
Information on pulse measuring
Only one kind of pulse measuring is possible at a time (ear-clip or cardio
pulse set).
Pulse calculation starts when the heart in the display flashes in accordan-
ce with your pulse beat.
With ear-clip
The pulse sensor operates with infra-red light and measures the changes
in the light permeability of your skin which are caused by your pulse beat.
Before you fasten the ear-clip to your ear lob please rub it strongly 10 ti-
mes, in order to increase blood circulation.
Avoid interfering impulses.
• Fasten the ear-clip carefully at your ear lob and try to find the most fa-
vourable point for sensoring (heart symbol flashes without interruption).
• Do not train directly under strong incidence of light, e.g. neon light, ha-
logen light, spot light, sunlight.
• Completely avoid any vibrations and wobbling of the ear sensor inclu-
ding cable. Always fasten the cable with the clip at your clothes or - even
better - at a headband.
With cardio pulse set
Please refer to the appropriate instructions.
Malfunctions in pulse display
Should any pulse detecting problems occur, please once again check the
above items.
Malfunctions at training computer
If the electronic system behaves strange or disturbed, press the reset key.
Information on interface
The training software "ERGO concept", art. No. 7926-000, to be bought
from your specialised dealer, permits the control of your KETTLER cross
trainer with a customary PC through this interface.
Soon you will find information about further possibilities with the interfa-
ce on our homepage www.kettler.net.
Under the item FAQ (frequently asked questions) you will find information
about the "electronic system" of our products.

Sport medicine and training scientists use the bicycle ergometry among
others to check the proper function of heart, cardiovascular and respira-

The sport medicine proceeds on the finding that the bodily functions can
