<Replacing the Battery>
• The battery of this watch must be replaced at a Citizen Service Center.
Please have the battery replaced at a Citizen Service Center.
• When replacing the battery, the service center also inspects water resistance
and performs other checks, including replacement of the packing as neces-
sary.
• All log memos, altitude memos and other data are erased as a result of bat-
tery replacement. Please retain a separate record of this data when it is
required for future use.
• Leaving the battery in the watch after it has become worn down can cause
leakage of battery fluid resulting in damage. It is recommended that you
have the battery replaced promptly.
• With long-term use of this watch overseas you run the risk of being unable to
have the watch serviced, if a malfunction should happen to occur, due to the
absence of a Citizen Service Center in some locations. It is recommended

formed prior to traveling overseas.
• Battery replacement and any accompanying inspections or parts replacement
are performed at normal service rates even during the warranty period.
