Battery Replacement
Leave battery replacement up to your original retailer or authorized CASIO service center.
Have the battery replaced only with the type specified in the “Specifications”. Use of a different battery type can cause malfunction.
When replacing the battery, 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.
Initial Battery
The battery that comes loaded in your watch when you purchase it is used for function and performance testing at the factory.
The test battery may go dead quicker than the normally rated battery life noted in the “Specifications”. Note that you will be charged for replacement of this battery, even if replacement is required within your watch’s warranty period.
Low Battery Power
Low battery power is indicated by large timekeeping error, by dim display contents, or by a blank display.
Operation while battery power is low can result in malfunction. Replace the battery as soon as possible.
