Removing/Setting the O-ring
When removing the O-ring for replacement,
cleaning or inspection, take care for the
following points.
If there is mud on the O-ring, or if the
camera has been in seawater, be sure to
remove the O-ring to clean and inspect it.
Removing the O-ring
Press lightly on the O-ring with your fingers
to shift it from the groove, grasp the slack
portion, and remove the O-ring.
• Do not use a pointed, sharp or metal object to
remove the O-ring. This can scratch the O-ring
or the O-ring mating surface which may allow
water to leak inside the camera.
• Do not place excessive tension on the O-ring.
Cleaning the O-ring and the O-ring
groove
• Use tap water at 30°C or less to wash the O-
ring that you removed. Wipe away any water
when finished.
• The O-ring is specially treated, so take care not
to allow grease or oil to adhere to the O-ring.
• When sand particles or encrusted salt may be
present in the O-ring groove, clean the groove
carefully using a cotton swab. Take care that
fibers from the cotton swab do not remain in the
groove.
• Do not use a pointed, sharp or metal object for
cleaning, as this may scratch the O-ring groove.
Setting the O-ring
Place the O-ring in the groove, taking care
for the following points.
• Do not place excessive tension on the O-ring.
• After setting, run a final check for any of the
following problems.
– Are there any water droplets on the O-ring?
– Is the O-ring twisted?
– Has any dirt, etc. adhered to the O-ring?
– Is the O-ring protruding from the groove?
O-ring life
• Replace the O-ring with a new one if it
becomes cracked, warped, crushed,
twisted, split, scratched, rough or
otherwise damaged. Even if the O-ring
has no problems, deformation and wear
over time can cause the waterproof
performance to drop, so replace the O-
ring with a new one after approximately
two years of use.
• Consult your Sony dealer or local
authorized Sony service facility for
replacement of O-rings. Order the
following parts number when purchasing
