(1) All battery replacement comes under Citizen Service Center repairs, so
request it at the place of purchase or send directly to a Citizen Service
Center.

replacement are carried out during battery replacement.
(3) All the log memo, from the maximum depth memo onwards, is erased by
battery replacement, so record it beforehand in a logbook.

cause damage by leaking. You are advised to replace the battery
immediately.
