ActilinoBattery ManagementPage 96If you require information about the battery, you can display all the important data in the(I)nfo menu, submenu (B)attery stats (see chapter 5.1.11.2).10.3 Automatic Recognition of Low VoltageThe Actilino includes battery voltage recognition in two steps. When the voltage falls to alow level, a warning signal sounds every minute. This indicates that battery capacity isnearing its end and that the battery should be recharged. You can turn the warning signaloff or on in the (O)ptions menu (see chapter 5.1.12.11 (T)one signals).When the lowest limit for the battery voltage has been reached at about 3 V, your Actilinoturns itself off. However, even in this state it uses up a small amount of electricity. You shouldtherefore never leave the Actilino in this state for longer than one day. It would be best if youbegin to recharge the battery immediately.If you expect not to use your Actilino for several weeks, either recharge the battery up to50% first or remove the battery completely from the device. Please be aware that a longbattery calibration is necessary after the removal of the battery to ensure a correct capacitystatus display.10.4 Replacing the BatteryThe Actilino contains a rechargeable battery which enables you to work for about 30 hoursindependent of a power source. The battery is fully charged prior to shipment, so that youcan begin working independent of any power source. The power supply included in thepackage allows you to recharge the empty battery.We recommend to remove the battery only if it is obviously broken and has to be substituted.As soon as you have removed and re-inserted the battery, a long battery calibration has tobe done to ensure a correct capacity status display. Therefore, the battery has to bedischarged and charged again completely (see chapter 5.1.12.21 Battery calibration: seemanual).The battery must be replaced from time to time because of aging. Please proceed as followsto replace the battery:1. Turn off the Actilino and disconnect all cables.2. If the Actilino is inside of its carrying case, make sure all cables are disconnected andtake it out of the case.3. Turn the device over horizontally, so that the control keys are underneath.4. The battery compartment is placed on the bottom of the housing and is secured by asnap catch.5. If you push the snap catch inwards using one finger, you can easily remove the lid ofthe battery compartment.6. Now you can remove the battery by lifting it out.7. When inserting the new battery, make sure that the electronic contact is placed ontothe contact pins inside the battery compartment.8. You lock the cover again by inserting its pins into the appropriate recesses on thehousing and then pushing down lightly on the catch. The catch snaps audibly intoplace.
