Wet the electrodes to the transmitter (the two grooved surfaces on the underside of the
strap) and secure the strap as high under the chest muscles as possible. The strap should
be snug, but comfortable enough to allow for normal breathing.
The transmitter strap will deliver an optimum heart rate reading when the electrodes are directly
in contact with bare skin. However, it will function properly through wet, lightweight clothing.
The key to proper operation is for the electrodes to remain wet to conduct the electrical
impulses of the heart back to the receiver.
If it becomes necessary to remoisten the chest strap transmitter, grasp the center of the strap,
pull it away from the chest to expose the two electrodes, then moisten them in this position.
