Intended use This appliance is intended for charging NiCd / NiMH rechargeable batteries of Size Micro AAA, Mignon AA, Baby C, Mono D and 9V battery packs, for personal and household purposes. It is not intended for charging commercial type batteries (even rechargeable types), or lithium-ion batteries, or for use in commercial or industrial applications. Never load commercially available non-chargeable batteries into the appliance ­ these can overheat and explode. Risk of injury! 2 2. Safety instructions. · Never leave the appliance to charge unsupervised. Batteries become hot once they are fully charged. Overcharged or faulty batteries can overheat and explode. Never touch batteries when they are hot ­ they might explode while they are being taken out. First disconnect the appliance from the power supply and allow the batteries to cool before taking them out. Never expose the appliance to other sources of heat, such as direct sunshine or heaters. This will prevent the batteries from overheating prematurely. If you are charging a number of batteries at the same time: Always insert only batteries that are similar, i.e. batteries of the same type, same level of charge, same size and same capacity. This will avoid some of the batteries becoming fully charged and overheating while the others are still charging. 3 · Set up the appliance in dry rooms only, never in humid areas. Otherwise there could be danger of death from electric shock. If the appliance is not working or is damaged, it should no longer be used. Have it repaired by customer service. If the power cord is damaged: The power cord cannot be repaired ­ have it replaced by customer service before using the appliance again. Never open the casing, there are no operating elements inside. Warning! Risk of accident! Do not allow children or elderly persons to play with the appliance unsupervised, since these are not always able to assess the dangers correctly. Batteries can represent a considerable danger for children, who might put the batteries in their mouth (they contain poisonous heavy metals), or shortcircuit them while playing with them. · · · · · · · 3.

Charging batteries Danger: Only charge batteries identified by the letters "NiCd" or "NiMH" . Never charge other types of batteries , even if these are "rechargeable". Such batteries require a quite different type of technology! If you place these batteries in NiCd/NiMH battery chargers, they can overheat and explode. a) Inserting batteries · Place the batteries the right way up, as indicated in the charging slots. Otherwise the charging process cannot start. b) Test the batteries first! If you do not know how charged or discharged your batteries are, you can test them as follows: Move the switch to the far left, to the position with the "partly charged batteries" symbol. · Then, connect the power plug to the power socket. The test indicator lightat the symbol is lit brightly if the battery is sufficiently charged. If the test indicator light is lit only faintly or not at all, then the battery is almost completely discharged or flat. Note: Only insert the battery in the slot on the far left is tested. If you would like to test the other batteries as well, they must be inserted one after the other into this slot. NiCd batteries should only be recharged when they are almost completely discharged. Otherwise, a "memory effect" is created, where the batteries reduce their capacity to the lower level at which they are actually used. NiMH are not susceptible to the "memory effect". 5 c) Discharge NiCd batteries first NiCd batteries that are not fully discharged should be discharged first, to avoid the possibility of "memory effects". If you have inserted up to 4 NiCd batteries, move the switch to the far right, to the position with the "Discharge" symbol. · Connect the power plug to the power socket. Allow the NiCd batteries to discharge until the test indicator light is barely lit, meanwhile testing the batteries a few times. Important: Do not allow NiCd batteries to become completely discharged, as this may ruin them. Therefore, do not allow the batteries to discharge until the test indicator light goes off completely. The Discharge feature is only available at the four charging slots for 1.2 V batteries ­ not for 9 V batteries. d) Charging batteries If you have inserted the batteries the right way up, as described at paragraph a) ... move the switch to the center, to the position with the "Charge" symbol, and ... · connect the power plug to the power socket. If all batteries have been placed correctly, the charge indicator LED lights up at each charging slot. Danger! If a charge indicator LED is not lit, even though the battery has been correctly inserted, then the battery is faulty. Do not, in any circumstances, attempt to charge a faulty battery. A faulty battery can overheat and then explode. · Only charge with the cover closed. This will provide sufficient protection against flying battery parts in the event of an explosion due to overheating. 6 e) Keep to the charging time! The best protection against battery overheating is not to exceed the proper charging time. If you wish to calculate the time exactly, please refer to the technical data for information about the charging current required. You can take the values in the following table as a rough guide: 1.2V NiCd battery 300 mAh Charging time: 1.5-2 hrs. 1.2V NiMH battery Charging time: 9V NiCd battery Charging time: 9V NiMH battery Charging time: 650 mAh 3 hrs. 100 mAh 5-11 hrs. 150 mAh 8-15 hrs. 500 mAh 3 hrs. 1700 mAh 9 hrs. 1200 mAh 9 hrs. 3000 mAh 15 hrs. All charging slots and 9 V connections have separate charging current controls. You can therefore charge completely different batteries at the same time ­ provided you observe the different charging times, required for batteries with different capacities. f) Charging time: Automatic cut-out If you have loaded four batteries of the same type in the 1.2V charging slots, you can use the automatic cut-out feature. With this feature, the appliance switches the 1.2V charging slots over to trickle charge after the pre-selected maximum charging time. This function is available for the 9V connections only. Turn the knob to about the time required (you can determine this time by referring to the table opposite). At the end of the charging time, the appliance switches over to trickle charge, and the green LED indicator at the "Battery" symbol is fully lit. If you do not want to use this function, set the knob to the maximum charging time of "15 h". 7 Warning: Batteries with a capacity of not more than 300 mAh should not be charged for more than 2 hours, as they would become overcharged and overheat. 5. Taking out batteries When charging is complete and you wish to take out the batteries, ... · first disconnect the power plug from the power socket, · wait until the batteries have cooled. · take out the batteries. 7. Storage If you are not going to use the appliance for a long period, disconnect the plug from the power socket and remove all batteries from the charging slots. Caution: If you do not take out the batteries, deposits can accumulate over time at the terminals, depending on the quality of the battery. Batteries can also leak and damage the appliance. · Store the appliance in a dry place. 6. Cleaning and Care Clean the appliance only when the plug has been disconnected from the power socket and all the batteries have been taken out. · Clean the appliance only with a dry cloth. Never use cleaning agents or solvents. These may cause damage to the appliance, and particularly to the labelling and plexiglas cover. · The terminals do not require cleaning, as they are chrome-plated and therefore dirt resistant. 8 8. Disposal Before disposing of the appliance, take out any batteries remaining inside. These should not be disposed of with the household waste. Take the appliance and batteries to your dealer, or to a suitable recycling center. Kompernaß Handelsgesellschaft mbH · Burgstraße 21 · D-44867 Bochum www.kompernass.com IDNr: KH967-03/04
