10 GBOperation Reset / deleting settingsAfter connection to the power supply, the applianceautomatically returns to its basic setting and remainsin STANDBY mode Switching between modes 1,2, 3 and 4 Press the MODE selection button 9 the appro-priate number of times.The device switches between charging modes inthe following order: Standby , MODE 1„6 V“, MODE 2 , MODE 3 , MODE 4and then repeats the cycleNOTE: If you press the selector button 9 , chargingmode automatically switches over to the next modeand begins operation in that mode.NOTE: However, if a battery is not disconnectedfrom the charging station after a full charge, theappliance remains in trickle-charge mode, even ifthe user switches over to another mode. This pro-tects the battery from being damaged. Mode 1 „6 V“ (7.3 V / 0.8 A)This mode is suitable for charging 6 V lead-acidbatteries with a capacity less than 14 Ah. Press the selection button MODE 9 , to selectmode 1. After doing so, the corresponding LEDdisplay „6 V“ 2 lights up. If you do not activatean-other process afterwards, the electronic sys-tem will automatically start the charging processtogether with the LED display 8 at (with acurrent of) 0.8 A ± 10 %. If the procedure runswithout any problems, the LED display 8remains on during the entire charging process, un-til the battery is fully charged at 7.3 V / ± 0.25 V.When the battery is fully charged, LED display7 lights up and LED display 8 goesout. The device now switches automatically intomaintenance charging mode. Mode 2 „12 V“ (14.4 V / 0.8 A)This mode is suitable for charging 12 V lead-acidbatteries with a capacity less than 14 Ah. Press the selection button MODE 9 , to activatemode 2. After completion of this process, theappropriate LED indicator 3 lights up.Then if you do not take any further action, theelectronic control and the LED indicator 8automatically switches on and starts the charg-ing process. If the procedure runs without anyproblems, the LED display 8 remains onduring the entire charging process, until thebattery is fully charged. When the battery isfully charged, LED display 7 lights up andLED display 8 goes out. The device nowswitches automatically into maintenance charg-ing mode. Mode 3 „12 V“ (14.4 V / 3.6 A)This mode is mainly suitable for charging 12 Vlead-acid batteries with a capacity greater than14 Ah under normal conditions. Press the selection button MODE 9 , to activatemode 3. Then if you do not take any further ac-tion, the electronic control and the LED indicator4 switches on and starts the chargingprocess. If the process runs without any problems,the LED indicator 8 remains on during thewhole charging process until the battery ischarged. When the battery is fully charged, theLED indicator 7 and the die LED indicator8 go out. The device now switches auto-matically into maintenance charging mode. Mode 4 „12 V” (14.7 V / 3.8 A)This mode is used for charging 12 V lead-acid bat-teries with a capacity greater than 14 Ah undercold conditions or for charging some AGM (Absorb-ent Glass Mat) batteries with a capacity greaterthan 14 Ah.
