12InstallationCharge DisplayThe charge status of the batteries is indicated on the display:ƒ batteries are 81 - 100% charged„ batteries are 61 - 80% charged√ batteries are 41 - 60% charged… batteries are 21 - 40% charged† batteries are 0 - 20% charged† (frame flashes) batteries are almost empty; a warning has been given.Your handset has a battery management system which has to ascertain the limits of the batterycharge status first before it can output the correct status to the display.When you insert the batteries for the first time, the charge status will not be displayed correctlyuntil they have been completely discharged and then completely recharged.When the handset is placed in the charger cradle, the flashing or lit segments indicate the chargingprocess or charge status respectively.Charge WarningWhen the batteries' capacity is almost exhausted, the battery icon in the display will flash, and anacoustic warning is given in the form of three short “beep” signals every minute. If you are making acall, you have approximately five minutes' talk time left before the handset switches itself off.Use only rechargeable NiMH batteries. Never use normal, nonrechargeable batteries or fuel cells (seepage 61).NoteYou can replace your handset in the charger cradle after every call if you wish. The charging processis electronically regulated so that the batteries are always optimally recharged, whatever theircharge level at the time. Do not remove the batteries from the handset unless there is a good reasonfor doing so. Removing the batteries interrupts the optimized recharging process.The capacity of the batteries can be increased by discharging them completely in the handset whenthey have been in use for a long period and then fully recharging them again.
