Frequently Asked Questions - BN-8 CORTEX

How do I assemble the Cortex BN-8 fitness equipment?

Assembly requires basic tools (included). Follow the step-by-step manual: attach the stabilizers, then seat post and handlebar post, then pedals and console. Tighten all bolts securely. Estimated time: 30 minutes.

How do I adjust the resistance?

Turn the resistance knob on the main frame clockwise to increase resistance and counterclockwise to decrease. The BN-8 has 8 magnetic resistance levels for a smooth, quiet ride.

The display is not turning on. What should I do?

Check that the batteries are installed correctly in the console (2 AA, not included). If still off, try replacing the batteries. Ensure the battery contacts are clean and making contact. If the problem persists, contact support.

How do I use the heart rate monitor?

Grasp the hand pulse sensors on the handlebars lightly with both hands. The display will show your heart rate after a few seconds (usually in beats per minute). For more accurate readings, pause pedaling and keep hands still.

Why is the pedaling not smooth?

First, check that the pedals are tightened properly. Then verify the resistance setting is not too high. If the sound is grinding, lubricate the crank axle with silicone spray (do not use oil). If problem continues, inspect the magnetic brake; contact support if needed.

Can I use the BN-8 if I weigh over 120 kg?

No, the maximum user weight is 120 kg. Exceeding this could damage the frame and cause safety hazards. Please respect the weight limit.

How do I clean and maintain the equipment?

After use, wipe the frame and seat with a dry or slightly damp cloth. Do not use harsh chemicals. Check all screws and bolts monthly and retighten if loose. Lubricate moving parts every 3 months with a light lubricant.

The seat is wobbly. How can I fix it?

Tighten the seat post adjustment knob and the bolts under the seat. If still wobbling, check if the seat post is properly inserted and not damaged. For replacement parts, contact Cortex.

What spare parts are available for the BN-8?

Commonly available spare parts include replacement pedals, seat cushions, handlebar grips, battery covers, and resistance knobs. Contact Cortex customer service or check online for part numbers.

How long is the warranty and what does it cover?

The Cortex BN-8 comes with a 1-year limited warranty covering manufacturing defects in materials and workmanship. Wear items like pedals and grips are not covered. For warranty claims, provide proof of purchase.

! PLEASE NOTE:

Before beginning any exercise program, consult your physician. This is important for individuals over the age of 45 or with pre-existing health problems.

The pulse sensors are not medical devices. Various factors, including the user's movement, may affect the accuracy of heart rate readings. The pulse sensors are intended only as an exercise aid in determining heart rate trends in general.

Exercising is great way to control your weight, improve your fitness and reduce the effect of aging and stress. The key to a healthy lifestyle is to make exercise a regular and enjoyable part of your everyday life.

The condition of your heart and lungs and how efficient they are in delivering oxygen via your blood to your muscles is an important factor to your fitness. Your muscles use this oxygen to provide enough energy for daily activity. This is called aerobic activity. When you are fit, your heart will not have to work so hard. It will pump a lot fewer times per minute, reducing the strain on your heart.

So as you can see, the fitter you are, the healthier and greater you will feel.

WARM UP

Start each workout with 5 to 10 minutes of stretching and some light exercises. A proper warm-up increases your body temperature, heart rate and circulation in preparation for exercise. Ease into your exercise.

After warming up, increase the intensity to your desired exercise program. Be sure to maintain your intensity for maximum performance. Breathe regularly and deeply as you exercise.

COOL DOWN

Finish each workout with a light jog or walk for at least 1 minute. Then complete 5 to 10 minutes of stretching to cool down. This will increase the flexibility of your muscles and will help prevent post-exercise problems.

WORKOUT GUIDELINES

This is how your pulse should behave during general fitness exercise. Remember to warm up and cool down for a few minutes.
