Getting started Low battery warning Your phone displays the Battery Low icon ( ) and a warning message when the battery gets low. If this happens, charge the battery using the travel charger. If the phone is nearly out of battery power, it shows the "Main Battery Very Low" message. In this case, you cannot perform a synchronisation without connecting the phone to a power source and the phone doesn't give you any instructions for saving data. Connect the charger to the phone immediately. Note: You must back up data in case of power cutoff. For details, see page 37. When the battery gets very low, the phone turns off the backlight to reduce the power consumption. 16 Adjusting the power settings You can conserve battery power by adjusting the Power settings. During standby, the phone goes to Sleep mode after a specified period of time of inactivity, so very little power is being consumed. This helps to preserve programmes and data stored in the RAM. A lower setting increases the usable battery time. A higher setting decreases the usable battery time and allocates it for standby usage.
