Pay careful attention while using the memory card, especially
while inserting and removing the card. Some memory cards
must be formatted on a computer prior to the initial use.
On the regular basis, make backup copies of data stored on
cards used in other devices, if you use the SD cards! Misuse
or other factors might damage the card or cause its content
to be lost.
Battery Installation:
•
Insert the battery so that the contacts +/- will go
towards the bottom of the phone.
•
After the battery is inserted, place the battery cover
back on the phone and slide it upwards.
