Training and Operating Instructions
General instructions
System signals
Activation of the device
If you activate the device, a signal is emitted during the segment test.
Presetting
A short signal is emitted, if you reach a presetting such as time, distance and KJoule/ kcal.
Maximum pulse exceeding
If the preset maximum pulse is exceeded by one pulse beat, 2 short signals are emitted for the time.
Recovery
Calculation of the fitness mark (F):
$$ \operatorname{mark} (F) = 6. 0 - \left(\frac {1 0 \times (P 1 - P 2)}{P 1}\right) ^ {2} $$
P1 stress pulse P2 = recovery pulse
Grade 1 = very good Grade 6 = insufficient
Calculation of average value
The calculations of the average values refer to training units in the past until a reset or the stand-by mode.
Instructions for pulse measurement
The pulse measurement starts as soon as the heart in the display blinks in time with your pulse beat.
With ear clip
The pulse sensor works with infrared light and measures the variations in translucence in your skin, which are produced by your pulse beat. Rub your ear ten times strongly to activate the blood circulation before attaching the pulse sensor to your earlobe.
Avoid disturbing pulses.
- Attach the ear clip properly to your earlobe and look for the best point for the measurement (heart symbol blinks without interruption).
- Do not train directly under strong incidence of light, e.g. neon light, halogen light, spotlights, sun light.
- Completely eliminate any shocks or bounces of the ear sensor and the cable. Always attach the cable with a clip at your clothing or, even better, at your headband.
With breast clip
Please observe the corresponding instructions.
With hand pulse
An extra-low voltage caused by the contractions of your heart is registered by the hand sensors and evaluated by the electronics assembly of the device
• Always grab the contact faces with both hands
- Avoid jerky grasping
- Hold your hands calmly and avoid contractions and rubbing on the contact faces.
Comment:
Only one way of pulse measurement is possible: either with ear clip or with hand pulse or with breast belt. If no ear clip or plug recipient is located in the pulse plug, hand pulse measurement is activated. If you insert an ear clip or a plug recipient in the pulse plug, hand pulse measurement is automatically deactivated. It is not necessary to disconnect the plug of the hand pulse measurement.
Battery change
If the battery symbol occurs in the display, battery power is too low for pulse measurement. Training kilometres and time as well as all presettings will get lost. Time must be reset.
Brake level display
Brake setting is classified in level 1-10. If this classification is disturbed or lost, you must restore it as follows:
- Check whether the 3-pole connecting cable is plugged in at the back of the display.
- Insert batteries and press the "DISP/SET" button until the segment test is completed.
- Turn back hand lever to minimum setting and press the "DISP/SET" button when 0%, BRAKE 0 is displayed.
- Pre-turn hand lever to maximum setting and press the "DISP/SET" button when 100%, BRAKE 10 is displayed.
The process is completed.
Training instructions
Sports medicine and training science use cycle ergometry, among other things, for the examination of the functional capability of heart, circulation and respiratory system.
You can find out whether or not you have achieved the desired effect from your training after several weeks using the following method:
- You manage a particular endurance performance with less heart / circulation performance than previously
- You sustain a particular endurance performance with the same heart / circulation performance over a longer period.
- You recover more quickly than previously after a particular heart / circulation performance.
Guide values for the endurance training
Maximalpulse: maximum strain means the reaching of the individual maximum pulse. The maximum achievable heart rate is dependant on age.
Here the following empirical formula applies: the maximum heart rate per minute corresponds to 220 heart beats minus age in years.
Example: age 50 years -> 220 - 50 = 170 pulse/min.
Load intensity
Load pulse: the optimum intensity of load is reached at 65–75 % (see also diagram) of the maximum pulse. This value changes depending on age.

| Age | Maximalpulse | Fitnesspulse | Fat combustion pulse | | --- | ------------ | ------------ | ------------------- | | 20 | 200 | 140 | 130 | | 30 | 180 | 130 | 120 | | 40 | 160 | 120 | 110 | | 50 | 140 | 110 | 100 | | 60 | 120 | 100 | 90 | | 70 | 100 | 90 | 85 | | 80 | 80 | 85 | 80 | | 90 | 60 | 80 | 75 |Extent of load
Duration of a training unit and its frequency per week:
The optimum extent of load is attained, if 65–75 % of the individual heart / circulation performance is achieved over a longer period.

It is recommended that you perform approx. 5 minutes of exercises before and after every training unit, in order to warm up and cool down. There should be a training-free day between each two consecutive training units, if you prefer training sessions of 20-30 minutes 3 times a week later on in your training. Otherwise, there is no reason why you should not train daily.
