HEART2feelX SOFT BELT

The chest strap must be positioned around your chest. when correctly placed, it sends heart

rate information to the watch located on your wrist. The watch then displays the heart rate

and provides other extra information (target zone, intensity of exercises) to manage and opti-

mize your fitness and training. The soft belt will be connected with two clips at the sensor

case. The rubber areas have to be placed on the skin (see photo below)

USING THE HEART2feel X SOFT BELT

1 Connect the soft belt with the sensor on one side. 

Push one bottom of the heart rate sensor on the strap.  

2 Wet both sensors on the back (rubber area) of the heart rate monitor to create a strong 

connection between your chest and the transmitter.

(for extremely dry skin use some special gel)

3 Wrap the strap around your chest and attach it to the other side of the heart rate monitor.

Reapply moisture to the sensors. Use water, saliva, or electrode gel. Clean the sensors. Dirt

and sweat residue on the sensor can interfere with heart rate signals.

Synthetic fabrics that rub or flap against the heart rate monitor can create static electricity

that interferes with heart rate signals.

NOTE: In cold conditions, wear appropriate clothing to keep the heart rate monitor near

your body temperature. Accuracy may be degraded by poor sensor contact, electrical inter-
