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 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)
]
2
P1
P1 = Strain pulse
P2 = Recovery pulse
Value 1 = very good Value 6 = insufficient
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 reco-
very key (8) and establish your fitness value, you should train for a longer
period, i.e. for at least 10 minutes, in your strain range. With a regular
cardiovascular training you will note that your "fitness value" improves.
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 hand
pulse sensors 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 hand pulse sensors
A very low voltage caused by the contraction of the heart is detected by
the hand sensors and assessed by the electronic system.
• Always grasp the contact surfaces with both hands.
• Avoid jerky grasping.
• Hold your hands calm and avoid contractions and rubbing on the
contact surfaces.
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.
10 Exercising instructions
Sport medicine and training scientists use the bicycle ergometry among
others to check the proper function of heart, cardiovascular and respira-
tory system.
The sport medicine proceeds on the finding that the bodily functions can
only be efficiently checked when on exertion. A cardiovascular examina-
tion in the state of rest can possibly not give any information about the
behaviour of the heart and cardiovascular system on physical exertion.
An exertion test, however, e.g. on the bicycle ergometer, can detect pos-
sible cardiovascular deficiencies and diseases. The appropriate measu-
res, e.g. a moderate cardiovascular endurance training on consultation
with the doctor, can be taken at an early stage/ in time.
Even in the framework of the rehabilitation of cardiovascular cases (car-
diac infarction convalescents, etc.), exercises on the bicycle ergometer
are of major importance. The exercise can be well-measured and the
exertion during exercise can be controlled at any time.
In competitive sports, the individual endurance of the athlete under opti-
mum conditions can be measured by means of bicycle ergometry. Con-
clusions on the fitness level of the athlete can be drawn from these results.
Even you as amateur fitness sports person who is only looking for bodily
exertion to avoid manifestations of degenerations of the cardiovascular
system or to improve your endurance should make use of the options the
bicycle ergometry offers.
The thoroughly trained athlete differs from the amateur sports person
among others in terms of the quick and abundant availability of the ener-
gy carriers required. This is the duty the "Cardiovascular /respiratory sy-
stem" transport system has to perform: to achieve maximum results with
the least possible effort.
To find out whether your fitness endurance training has achieved the de-
sired effects/adaptations after some weeks of regular cycling exercise see
