Slide the SIM card out of the SIM card holder. Battery The battery that comes with your R380 is a lithium ion (Li-Ion) battery. The battery is not fully charged when you buy your phone but there may be enough power to turn it on. We recommend that you charge the battery for four hours before you use the R380 for the first time. The first time you charge a new battery, or a battery that has been completely discharged, it may take a few minutes before you get any indication that the battery is being charged (the Status indicator does not light up and the battery meter does not display). Note: You cannot turn on the R380 before the Status indicator lights up and the battery meter displays. A battery that has not been used for a long period needs to be completely discharged and then recharged 2-3 times before reaching full capacity. Should you need to discharge the battery, simply use your R380 as usual until the battery runs low. Preparing for Use 11
