Continued use of the watch while it is smoking, emitting foul
odor, generating heat, or otherwise demonstrating
abnormal symptoms creates the risk of fire and electric
shock. Immediately take the actions below.
1. If a charging is in progress, unplug the USB cable from the

3. Contact an authorized CASIO Service Center.
Regardless of the information displayed by the watch, be

your exertion level within your own personal capabilities.
Whenever working out while using the watch to monitor your heart
rate or to perform any other type of training measurement, take
