clear of moisture.

∫ About the water draining design
This unit is designed so that water that entered the gaps around the
zoom button etc. drains out. For this reason, bubbles may appear when
the unit is immersed in water, but this is not a malfunction.
Draining water from the unit
Drainage holes are found on the bottom of the unit. Hold the unit
vertically, as shown, to drain off the water.
When draining, attach the hand strap to the unit and secure the hand
strap to your wrist to prevent the unit from dropping. (l 15)
