Tunturi C20 사용자 설명서

Do not route the power cord beneath a carpet and 

do not place any objects on the cord. 

Disconnect the plug from the power outlet 

before you move the unit, perform any needed 

maintenance or open the housing.

Do not alter (for example, lengthen) the cord 

between the transformer and the unit.

If the product is not stable, adjust the stabilizing 

screws under the rear support appropriately.

If you feel sideway play in the pedal cranks, tighten 

the front end shaft nuts until the play disappears.

Exercise intensity can be increased or decreased 

with ”+/- ” keys: ”+” increases the resistance and 

”-” decreases the resistance.

Working out using an exercise cycle is excellent 

aerobic exercise, the principle being that the 

exercise should be suitably light, but of long 

duration. Aerobic exercise is based on improving 

the body’s maximum oxygen uptake, which in turn 

improves endurance and fitness. The ability of the 

body to burn fat as a fuel is directly dependent on 

its oxygen uptake capacity. Aerobic exercise should 

above all be pleasant. You should perspire, but you 

should not get out of breath during the workout. 

You must, for example, be able to speak and not 

just pant while exercising. You should exercise at 

least three times a week, 30 minutes at a time, to 

reach a basic fitness level. Maintaining this level 

requires a few exercise sessions each week. Once 

the basic condition has been reached, it is easily 

improved, simply by increasing the number of 

exercise sessions. Exercise is always rewarding for 

weight loss, because it is the only way of increasing 

the energy spent by the body. This is why it is 

always worthwhile to combine regular exercise 

with a healthy diet. A dieter should exercise daily 

- at first 30 minutes or less at a time, gradually 

increasing the daily workout time to one hour.

You should start slowly at a low speed and low 

resistance, because for an overweight person 

strenuous exercise may subject the heart and 

circulatory system to excessive strain. As fitness 

improves, resistance and speed can be increased 

gradually. Exercise efficiency can be measured by 

monitoring the pulse. The pulse meter helps you 

monitor your pulse easily during exercise, and thus 

to ensure that the exercise is sufficiently effective 

but not over-strenuous.

No matter what your goal, you’ll get the best 

results by training at the right level of effort, and 

the best measure is your own heart rate.

Pulse is measured wiith sensors which are located 

in the hand supports and which measure the 

pulse each time the user touches both sensors 

simultaneously. For reliable pulse measurement, 

the skin must be in continuous contact with the 

sensors and the skin in contact with the sensors 

should be slightly moist. Too dry or too moist 

skin will impair hand pulse measurement. Please 

note also that active use of the upper body muscles 

during exercise may interfere with hand pulse 

measurement: active muscles transmit similar 

electronic signals as the heart muscle. Therefore, 

we recommend that arms be kept relaxed during 

pulse measurement.

First find your maximum heart rate i.e. where the 

rate doesn’t increase with added effort. If you don’t 

know your maximum heart rate, please use the 

following formula as a guide:

This is an average value and the maximum varies 

from person to person. The maximum heart-rate 

diminishes on average by one point per year. If you 

belong to a risk group, ask a doctor to measure 

your maximum heart rate for you.

We have defined three different heart-rate zones to 

help you with targeted training.

BEGINNER • 50-60 % of maximum heart-rate.

Also suitable for weight-watchers, convalescents 

and those who haven’t exercised for a long time. 

Three sessions a week of at least a half-hour each 

is recommended. Regular exercise considerably 

improves beginners’ respiratory and circulatory 

performance and you will quickly feel your 

improvement.

TRAINER • 60-70 % of maximum heart-rate.

Perfect for improving and maintaining fitness. 

Even reasonable effort develops the heart and lungs 

effectively, training for a minimum of 30 minutes 

at least three times a week. To improve your 

condition still further, increase either frequency or 

effort, but not both at the same time!

ACTIVE TRAINER • 70-80 % of maximum 

heart-rate.

Exercise at this level suits only the fittest and 

presupposes long-endurance workouts.
