If the scales are adjusted correctly on both sides but the plates are not locking, contact your place of purchase to repair/replace the handle.
If the dial is unable to rotate during use, follow the steps below:
Remove the dumbbell from the base.
Press the reset button (Fig. 2) while rotating the scale to the minimum on both left and right side. Then the dumbbell will detach from the handle.

EXERCISE GUIDE

PLEASE NOTE:
Before beginning any exercise program, consult your physician. This is important especially if you are over the age of 45 or individuals 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 a great way to control your weight, improve your fitness and reduce the effect of aging and stress. The key to success 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 wear and tear of 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

$CORTEX-24kg-Adjustable-Dumbbell-FIG- $6$$

This is how your pulse should behave during general fitness exercise. Remember to warm up and cool down for a few minutes.
The most important factor here is the amount of effort you put in. The harder and longer you work, the more calories you will burn.
