Heart Rate Monitor Functions

The back cover of the watch has a built-in sensor that detects your pulse.
This is used to calculate and display an approximate heart rate value. The
factors below can cause error in the displayed heart rate value.
How the watch is affixed to the wrist
Individual wrist characteristics and conditions
Activity type and intensity
Sweat, dirt, and/or other foreign matter near the sensor
All of this means that heart rate values displayed by the watch are
approximate, and no guarantees are made concerning their accuracy.
The heart rate monitor function of this watch is intended for recreational
purposes, and should not be used in any way for medical purposes.

Band

A band that is snugly tightened for heart rate monitoring can cause you to
sweat and make it difficult for air to pass under the band, which can lead to
skin irritation. During normal wear, when you do not need to monitor your
heart rate, make sure the band is loose enough to allow you to insert a finger
between it and your wrist.
Deterioration, rust, and other conditions can cause the band to break or
come off of your watch, which in turn can cause band pins to fly out of
position or to fall out. This creates the risk of your watch falling from your
wrist and becoming lost, and also creates the risk of personal injury. Always
take good care of your band and keep it clean.
Immediately stop using a band if you ever notice any of the following: loss
of band flexibility, band cracks, band discoloration, band looseness, band
connecting pin flying or falling out, or any other abnormality. Take your
watch to an authorized CASIO service center or to your original retailer for
inspection and repair (for which you will be charged) or to have the band
replaced (for which you will be charged).
