While charging is in progress, the battery level indicator scrolls on the phone display. 3 When the battery is fully charged, the bars stop scrolling and four bars are displayed. You may now remove the charger plug from the communicator. Note: You can use all the features of the communicator during charging. When the battery level is low and only a few minutes of operation time remain, a warning tone will sound, and the message BATTERY IS LOW will be repeated at regular intervals on the phone display. When the charge level becomes too low for operation, the RECHARGE BATTERY message will be displayed, accompanied by a warning tone. If you do not connect the communicator to a charger, the communicator switches itself off. Note: When you connect a communicator with a fully discharged battery to a charger, it will take 30-60 seconds before the CHARGING message appears on the display and the battery indicator bar starts scrolling. After that, it may take 10-30 seconds before you can switch the phone on. WARNING: Keep all SIM cards and memory cards out of the reach of small children. Battery information Use the battery only for its intended purpose. Never use any charger or battery that is damaged or worn out. Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (for example coin, clip, or pencil) causes direct connection of the + and - terminals of the battery (metal strips on the bottom of the battery), for example, when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object. Tip: Read this section for information on how to prolong the life of your battery.
