Note: If you remove the battery for a long time, the phone will ask you to reset the time and date. If you choose to cancel or ignore, the time and date will be affected. You can input the correct time and date by:
Find it: Press M > Setting > Initial Setup
>Time and Date
But, if you remove the battery just for a few seconds (e.g., quickly change SIM card), the system either won’t ask you to reset the time and date or if prompted, you can choose BACK on the time and date screen, the clock will only be slightly affected.

Before you can use your
phone you need to completely charge the battery. New batteries are
not fully charged. Plug the travel charger into your phone and an
electrical outlet. Your phone displays Charge Complete when finished.
Tip: You cannot overcharge your battery. It will perform best after you fully charge and discharge it a few times.
New batteries are shipped partially charged. Before you can use your phone, install and charge the battery as described below. Some batteries perform best after several full charge/discharge cycles.
