Memory card formatting
The format is necessary in the following situations:
1. Unformatted SD card
2. Reformat the card when it does not work in camera properly although it has
been formatted before;
3. It is important to format the card first when using it in another camera.
Attention: please keep the card in "unlock" status before using. All data will be
deleted and irrecoverable when the card is formatted. Please download all images or
backup the data before formatting.
Security

To avoid the danger of electric shock, do not open the camera or fix the camera
by yourself.

Even though this is a water resistant camera you should not open the battery
compartment with wet hands. Dry the camera very well before removing the SD
card or changing the batteries. If water enters the battery compartment this will
ruin the camera and cause the camera to stop working.

Stop using the camera immediately if water enters the battery compartment. Dry
the camera well with a clean cloth or towel. Leave the camera to dry in the air
before reusing.

Before using underwater, be sure to lock the battery door properly following
the steps as explained in the Preparing your Camera for Use section, and do
not open the battery door underwater.
