Be careful while using your memory cards,
especially while installing and uninstalling them.
Some memory cards must be formatted on a PC
before the first use. Make backup copies of data
stored on the cards used in other devices, if you use
SD cards! Misuse or other factors might cause
damage or loss of data stored on the cards.
 Insert the battery with the contact pins +/-
facing downwards (1), and next install the
battery in place.
