How do I replace batteries?
• Leave battery replacement up to your original retailer or authorized CASIO service center.

• Have the batteries replaced only with the type specified in the User’s Guide. Use of a different battery type can cause malfunction.

• When replacing the batteries, also request a check for proper water resistance.

• Ornamental resin components may become worn, cracked, or bent over time when subjected to normal daily use. Note that if cracking or any other abnormality indicating possible damage is noticed in a watch submitted for battery replacement, your watch will be returned with an explanation of the abnormality, without the requested servicing being performed.
