The O-ring is a consumption product. Please replace it at least once a
year with a new one. Also perform maintenance with every use.
Deterioration of the O-ring will progress according to the conditions of
use and the storage conditions. Immediately replace the O-ring with a
new one if it is damaged, shows cracks, or has lost its elasticity.
At the time of O-ring maintenance, clean the inside of the O-ring groove
and confirm the absence of dirt, dust, sand, and other foreign matter.
Apply the specified silicone O-ring grease to the O-ring.
The waterproof function is not effective when the O-ring is not installed
correctly. When installing the O-ring, take care that it does not project
from the groove and that it is not twisted. Also, when installing the
battery cap, close it after confirming that the O-ring has not come out of
the groove.
