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 9,5 km/h.
Kilojoule calculation
The performance is entered in Watt (current performance) and the time in se-
conds. Factor 8 results from the efficiency degree of a human being of ap-
prox. 12,5% when training with the trainer. However, this is only a clue.
kJ = performance x time x 8

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 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

]
Value 6 = insufficient
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 Training instructions
Cross training is a very effective training for the whole body straining all lar-
ge muscle groups and simultaneously training the cardiovascular system in
an ideal manner and supporting the fat metabolism. The innovative elliptical
motion of the stepping surfaces strengthens the leg and gluteal muscles par-
ticularly joint friendly. The upper body training coupled with leg training par-
ticularly trains arm, shoulder, chest and back muscles.
Before starting to train you should read the following information carefully!
Important note:
Before taking up training with the cross trainer, have your family doctor
check that you are fit for this kind of fitness training. The medical report
should be the basis for building up your training program.
The above and the following training information are only recommended
for persons with a healthy cardiovascular system.
Training information
Training with the cross trainer has to follow the principles of stamina trai-
ning. Stamina training predominantly causes changes and adjustments at
the cardiovascular system. These include a reduction of the resting pulse
rate and of the exercise pulse. This gives the heart more time for filling the
ventricles of the heart and for supplying the cardiac musculature with
blood (through coronary vessels). Furthermore, depth of respiration and
volume of air that can be inhaled (vital capacity) increase. Further positi-
ve changes take place in metabolic system. In order to achieve these po-
sitive changes, your training has to be planned according to certain prin-
ciples.
Planning and control of your cross training
Basis for training planning is your current physical capacity. With an
exercise test your family doctor can assess your personal capacity which
will for the basis for your training planning. If you have no exercise test
performed, high training strains and/or overloading are to be avoided
by all means. The following principle should be taken into account for
planning: Stamina training is controlled both over the volume of strain
and over the intensity of strain.
