Properties This is a fast charger for nickel/cadmium and nickel/metal hydride accumulators. The microcomputer-controlled fast charge charges the accumulators to 100%. 100% means up to 115% of the stated capacity with new accumulators and less than 100% of the stated capacity with older accumulators. With accumulators with a capacity of less than 500 mAh, the discharge capacity (D) may not reach 100%. However, this discharge value must be larger than 80%, otherwise the accumula- tor is defect (best test it with the ALIVE program). With this charger, it is not necessary to discharge the accumulators prior to recharging. The accumulator is charged from its current charge state to its presently possible 100%. The charging and discharging cycle is controlled independently of the charge state of the accu- mulator. The charge and discharge current is microcomputer-controlled. The discharge current of the charger is practice-conform (16 mA to 850 mA). The charger has an automatic sustain charge. The charger has an automatic fan control. The fan, which only runs slowly in standby-operation, automatically accelerates to maximum speed when charging or discharging an accumulator. If the charger detects a defect fan, all programs are cancelled, an error message is issued (FAN ERROR) and the charger no longer reacts. The charger has an automatic accumulator monitoring (charge voltage and charge quantity). The automatic accumulator detection notices when an accumulator is inserted or removed from the charger. There is no memory effect (charge and discharge current are clocked). This reduces the high interior resistance of the accumulator and its power capacity increases. The accumulator's degree of effectiveness increases (relation of the required charge quantity to the usable capacity). The charger has a memory backup. In case of power failure, the accumulator's data and the current functions are saved for up to two days. Once the charger is reconnected with the mains, the program is continued. To do so, the charger must have been connected with the mains for at least two hours beforehand and turned on. The LCD (alphanumerical) serves to display - the program (CHA, DIS, CHK, CYC, ALV) - the type of accumulator (BABY/MONO, MIGNON, MICRO, 9V block) - the accumulator's charge status (battery symbol) - the current accumulator voltage(U) - the current charge respectively discharge current (I) - the current respectively saved charge data (C) and discharge data (D) in mAh or Ah - the required time in hours and minutes (TIME hh:mm) There are three function keys for entering the programs and the settings.28 All available accumulator data can be displayed. You can display the accumulator data of all accumulators inserted in the slots with the two SELECT buttons (UP and DOWN). If all data of the slots in which accumulators are located was displayed, the overview appears again at the next push of the button. With the display of the individual accumulator data, the overview is displayed again when pressing the OK button. In the general overview, the OK button serves to adjust the display contrast. Overview Display: Here you see the overview of all inserted accumulators with the corresponding program and the charge status (battery symbol). If the charge status of the accumulator was not determined yet, a question mark appears ("?"). When the accumulator is treated, the battery symbol or an arrow alternate. When a charge is currently taking place, the arrow points upwards, if the accumula- tor is currently discharged, the arrow points downwards. If the POWER mode was turned on, "*PM*" blinks in the center of the second row. Display of Accumulator Data The charge program (e.g. CHARGE) and the charge capacity (C) is displayed in the first row. The status of the POWER mode appears in the second row, the accumulator symbol (?) shows the approximate charge status of the accumulator and the discharge capacity (D) is displayed. When charging is currently taking place, an arrow blinks in front of "C" and if a discharge is cur- rently taking place, an arrow blinks in front of "D". The third row displays the accumulator type and the measured accumulator voltage. The fourth and last row displays the already passed processing time (TIME) in the format "hh:mm". The charge respectively discharge current is also displayed. . ATTENTION! Remove the accumulator again immediately if the accumulator type (MONO/BABY, MIGNON or MICRO) is displayed wrong. Observe the correct fit when inserting the accumu- lator. If no voltage was determined yet, appears. A running program can only be cancelled by taking out the accumulator. If the accumulator is removed during charging or discharging, ERR for ERROR or RDY for READY may appear briefly, as the device notices that current no longer flows respectively that the discharge volt- age was undercut. If a program was performed successfully, RDY respectively READY appears and the display stops blinking. U= --.---V 1:CHARGE > C=123.1mAh PM OFF ? D= 0.0mAh

Charge Types There are two different charge types: fast charge and POWER mode. With fast charging, the charge current is approx. 350 up to 2000 mA. In the POWER mode, the charge current doubles with round cells. For the two 9V block accumulators, the POWER mode has no significance (the charge current remains the same). ATTENTION! When the POWER mode is on, please note that NiCd and NiMH accumula- tors may be charged with maximum 1C. Therefore, the inserted micro accumulators have to have a minimum nominal capacity of 700 mAh, MIGNON min. 2000 mAh and BABY accumulators at least 4000 mAh! The total charge current of this charger is 16 ampere. As soon as these 16 ampere total charge current are reached, another inserted accumulator is set to BREAK and only treated when the total charge current is reduced (when another accumulator is finished). Mono and baby accumulators may only be charged in the slots 1 to 4 in POWER mode (only slot 1 to 4 can charge with 4000 mA). If these accumulators are inserted in slots 5 to 8, ERROR appears. Charge current with POWER mode (approx.) without POWER mode (approx.) MONO/BABY: 4000 mA (slot 1-4) 2000 mA MIGNON: 2000 mA 1000 mA MICRO: 700 mA 350 mA 9V: 21 mA 21 mA Charge and Discharge Data The capacity charged in the accumulator (C) and the discharged capacity (D) is stated in mil- liampere hours (mAh) or ampere-hours (Ah). With the programs CYCLE and ALIVE, the old data is deleted with renewed charging respectively discharging. The capacity during trickle charge is not calculated, not displayed and also not added. Commissioning Remove all possibly inserted accumulators, plug the charger in and turn it on with the POWER switch on the back of the device. You will see the following displayed on the display for approx. 2 seconds: In this time, the charger performs a self-test and also checks for possibly inserted accumula- tors. This is necessary for the preserving the memory of all data in case of a power failure (memory backup). Now leave the charger switched on for at least 2 hours so that the integrated gold cap can charge to maximum. This gold cap serves to store all data for at least 48 hours when the charg- er is turned off or in case of power failure. Of course, the device is completely operational dur- ing this time.

Introduction Dear customer, Thank you for purchasing this charger. With this charger, you have purchased a product that reflects the latest state of technology. The structure corresponds to Protection Class 2. This product fulfils the requirements of the valid European and national guidelines. The conformity was proven and the corre- sponding declarations were deposited with the manufacturer. In order to maintain this condition and ensure safe operation, you as the user have to observe this operating manual. Intended Use This charger serves exclusively for charging up to eight nickel/cadmium respectively nickel/metal hydride round cell accumulators size mono, baby, mignon and micro simultane- ously. Additionally, you can charge two 9V block accumulators made of nickel/cadmium respectively nickel/metal hydride in the intended slots. These block accumulators may consist of 6, 7 or 8 cells. There is no restriction regarding the maximum nominal capacity (stated in mAh or Ah) of the accumulator to be charged. This charger serves exclusively for charging the stated accumulators. You may not charge oth- er types of accumulators! You may neither charge nor discharge lithium-ion accumulators, rechargeable alkaline and dry batteries (primary cells) with this charger. Non-rechargeable batteries may not be charged! This charger is constructed in Protective Class II. The charger may be connected to alternate cur- rent nets from 100 V~ up to 240 V~. The net frequency must be 50 or 60 Hz. Use is only permitted in closed rooms, meaning not out in the open. The contact with moisture, e.g. in bathrooms and similar rooms has to be avoided at all cost. Another use than the one described above leads to damages to the product and is also asso- ciated with dangers like short circuit, fire, electric shock, etc. The entire product may not be altered respectively modified and the casing may not be opened. The safety notices have to be observed under all circumstances!

ATTENTION! Other repairs than the ones described above may only be performed by an authorised expert. Overview Contrast The reading angle of the display depends on the location of the charger. Depending on the angle of view, you can adjust the good readability of the writing with the menu "DISPLAY CON- TRAST" with a high or low position of the charger. POWER MODE If no accumulator is inserted, you can activate the POWER mode: this doubles the charge cur- rent for the eight round cells. The inserted micro accumulators have to have a minimum nominal capacity of 700 mAh, MIGNON min. 2000 mAh and BABY accumulators at least 4000 mAh for the POWER mode! You can only charge MONO and BABY accumulators in slot 1 to 4 while the device is in POW- ER mode. Procedure Insert the accumulator. If the accumulator is not detected automatically, check the polarity. Then set the program with the two SELECT buttons and conform with OK. In case of a wrong program, take out the accumulator, reinsert it and enter the program anew! You can select the charge types CHA, DIS, CHK, CYC and ALV. At the start of the program, the fan (which is only running slowly) switches to maximum capac- ity and becomes perceivably louder. READY (RDY) appears in the display when the charging of the accumulator is done. Now you can take out the accumulator. The three buttons serve to display the individual slots during the processing of a program and to adjust the display contrast. In case of power failure or when the device is unplugged or switched off, the data and settings are preserved as long as the accumulator is not taken out. ERROR (ERR) This appears if a MONO or BABY accumulator was inserted in slots 5 to 8 in POWER mode, if a (non-rechargeable) battery was inserted or if another error has occurred. BREAK (BRK) The total charge current of 16 A was exceeded. The accumulator is charged automatically as soon as another accumulator is finished. Technical Data This charger serves exclusively for charging up to eight nickel/cadmium respectively nickel/metal hydride round cell accumulators size mono, baby, mignon and micro simultane- ously. Additionally, you can charge two 9V block accumulators made of nickel/cadmium respectively nickel/metal hydride. These accumulators may consist of 6, 7 or 8 cells.24 Main Menu If no accumulator is inserted, you can turn on the POWER mode. The display contrast can be changed at any time (also during charging). Charge Programs - CHARGE = charge respectively recharge once only . CHAR (CHARGE) means that the inserted accumulator is charged. - DISCHARGE = discharge only once DISCHARGE means that the inserted accumulator is discharged only. - CHK (CHECK) = discharge once and recharge - CHECK means that the inserted accumulator is discharged and charged again. - CYC (CYCLE) = charge / discharge / charge CYCLE means that the inserted accumulator is first charged, then discharged and finally charged again. - ALV (ALIVE) = charge / discharge / charge / discharge / charge The ALIVE program serves to revive new accumulators stored over a longer period of time. If an accumulator is already treated in slot 1, the selection starts with the same program as this accumulator (SAME AS SLOT 1); otherwise the selection starts with CHARGE. Please note that new and possibly improperly treated accumulators may at first only take up 30% of their capacity. This bad degree of effectiveness is indicated by a high charge capacity (C)and a very low discharge capacity (D). Charge these accumulators with the ALIVE program. After some cycles, the usable capacity (D) increases. NiCd and NiMH accumulators should be charged with C/3 up to 1C. Accumulator Voltage The accumulator voltage is stated in the deactivated state (and can therefore not be measured during operation). If no voltage U is displayed, the charger hasn't determined it yet. Accumulator Status In order to obtain a fast overview of the status of the accumulator to be charged respectively discharged, this device displays a battery symbol. This symbol merely serves to be able to tell at a quick glance how far the charge respectively discharge process has already advanced. Here, the battery symbol is filled from the bottom to the top during charging, while it is emptied from the top to the bottom when discharging. This does not allow any conclusions about the time remaining until the end of the program. When the charge status of the accumulator was not determined yet, a question mark appears in place of the battery symbol (in this manual, the battery symbol is generally portrayed with a "?". Charge and Discharge Current The current I flowing through the accumulator during charging and discharging is displayed. If no current was determined at the start of a program or if there is no current running after the end of the program (READY/ERROR), I = 0.000 A appears. Times The complete time in which the accumulator was charged and discharged is displayed in hours and minutes (TIME hh:mm). The time during trickle charge (TRICKLE) and during breaks (BREAK) is not added. If an accumulator exceeds approx. 80% of its maximum capacity during charging, a part of the charge current is converted to heat. This may cause the accumulator to heat up.

Now you can take out the accumulator. If you leave the accumulator in the charger and if required for the accumulator, the trickle charge program TRICKLE (TRI) is started automatically. This means that the accumulator is recharged (this naturally does not apply if the accumulator was merely discharged with the pro- gram DISCHARGE). The capacity (C) of the trickle charge and the time required for this (hh:mm) is not displayed or added. Only the voltage and the current are constantly updated. Therefore, the charge capacity, the discharge capacity and time only always refers to the processed program. When the charge was not successful, an error message ERR respectively ERROR appears and the charger no longer handles this accumulator. If the 16 A total charge current were already reached, each additional accumulator is set to BREAK. These accumulators are charged automatically as soon as another accumulator is fin- ished. This charger has a memory backup, meaning that the program and the added capacity values of the accumulator are saved in case of a power failure. Therefore never change the accumula- tor when the charger is off, as it otherwise takes over the no longer valid values and would thus determine wrong values for the new accumulator! If the charger is turned off during program selection, selection starts anew. The programs can only be continued if the integrated gold cap was previously charged (this requires that the charger was turned on for at least two hours). ATTENTION! All inserted round cell accumulators must be fast-charge capable in POWER mode. Please note that the inserted micro accumulators have to have a minimum nominal capacity of 700 mAh, MIGNON min. 2000 mAh and BABY accumulators at least 4000 mAh in POWER MODE! 1:BREAK C= 0.0mAh PM ON ? D= 0.0mAh

3:--- *PM* 4:--- 5:--- A:--- 6:--- 7:--- B:--- 8:---26 Without inserted accumulators, the standby display appears: The lines "---" mean that there is no accumulator inserted in these slots. The numbers 1 to 8 stand for the 8 slots in which you can insert the mono, baby, mignon or micro accumulators. The arrangement on the display corresponds to the arrangement of the slots. The letter "A" corresponds to the left 9 Volt slot, the letter "B" corresponds to the right 9 Volt slot. If no accumulator is inserted, you can turn the POWER mode on and off with the two SELECT buttons (UP and DOWN) and adjust the display contrast in three stages. POWER MODE means that all eight round cells are charged with twice the current. ATTENTION! All inserted round cell accumulators must be fast-charge capable in POW- ER mode. Please note that the inserted micro accumulators have to have a minimum nominal capacity of 700 mAh, MIGNON min. 2000 mAh and BABY accumu- lators at least 4000 mAh in POWER MODE! You can select the POWER mode with the two SELECT buttons (UP and DOWN) and confirm them with the OK button. After pressing the OK button, you can adjust the display contrast. During charging, you cannot change the POWER mode. When pressing OK, you go straight to the menu with the display contrast. You can set the contrast to "LOW", "MID" and "HIGH" with the two SELECT buttons (UP and DOWN) and confirm the entry with the OK button. Now insert an accumulator size MONO, BABY, MIGNON or MICRO into one of the 8 slots. Observe the correct polarity: the positive pole of the accumulator always has to point inwards towards the charger and the negative pole outwards. CHARGE- MANAGER 2020 ==================== DISPLAY CONTRAST <> MID CHARGE- MANAGER 2020 ==================== POWER- MODE <>

The charger detects this accumulator and starts querying the program settings. Now you merely need to select the charge program with the two SELECT buttons (UP and DOWN). Five different programs are available. These programs have the following functions: CHA (CHARGE) means that the inserted accumulator is fast-charged. DIS (DISCHARGE) means that the inserted accumulator is discharged only. CHK (CHECK) means that the inserted accumulator is discharged and charged again. CYC (CYCLE) means that the inserted accumulator is first charged, then discharged and finally charged again. ALV (ALIVE) means that the accumulator is charged / discharged / charged / discharged and charged again. The ALIVE program serves to revive new accumulators and accumulators stored over a longer period of time. You now have five seconds to select the program. After each press of the button for changing the charge program, you have once again 5 seconds. After these 5 seconds, the setting is tak- en over and the program activates. You can also press "OK" for confirmation. Without an entry, the program CHARGE starts. If a program was already started in slot 1, "- ADJ SAME AS SLOT 1" appears. This means that this accumulator is charged with the same program as the one in slot 1. So if you want to charge several accumulators with the same program, first insert an accumu- lator in slot 1 and select the desired program. Then insert the remaining accumulators; these are then charged with the same program without the push of any button. The built-in fan runs with maximum power when starting the device. With the programs CHA, CYC and ALV, the device starts charging, with the programs DIS and CHK, it starts discharg- ing. CHA = Charge once only DISCHARGE = discharge only once CHK = Discharge / charge CYC (CYCLE)= charge / discharge / charge ALV = Charge - discharge - charge - discharge - charge
