I

Seal the marine case.
z Make sure that the O-ring is not twisted, 

and that you did not forget to attach it.

z Make sure that foreign objects (strap, belt, 

dirt, etc.) have not been caught in between.

z The risk of water leakage is extremely high if 

the O-ring is twisted, if you forget to attach it, or 
if something is trapped in the seal.

J

Check that all the operation buttons of the 
camera are functioning properly.
z If it is not functioning, take out the camera 

and insert again.

K

Attach the grips.
z Attach the grips, lights or weights on the 

bottom of the marine case.

Submerge the marine case with the camera 
inserted into a bathtub or water tank full of fresh 
water. Gradually prolong the time the marine case 
is submerged as follows.

z 1st time: 5 ~ 10 seconds
z 2nd time: 30 seconds ~ 1 minute
z 3rd time: 3 minutes ~ 5 minutes (try operating 

the levers and buttons while the marine case is 
submerged).

z Always have someone hold the marine case 

for you when diving into, or getting out of 
water, to prevent loss or damages.

z If for any reason water leakage occurs, remove 

the camera battery. It may cause the camera to 
explode.

A

Turn on the camera’s power.
z Press and hold the power button for more 

than 2 seconds to turn on the power. (The 
camera’s power lamp lights and the 
monitor turns on.)

z Sometimes, due to sudden shaking or 

impact to the marine case, the camera’s 
drop detection function operates to turn off 
the camera’s power. When the camera’s 
power is turned off, turn it on again.
