P 3 / 5 Features and benefits New charging system for Ni - MH . battery The electronic charging control system proceeds the charging process . ( 1 ) with controlling the temperature rise on battery . ( 2 ) with corresponding to the battery's conditions ( its temperature , remaining capacity , serving time , etc . ) and outside temperature . ( 3 ) without shortening the battery's life . The relation of charging speed with temperature on battery just after finishing of charging process High The relation of charging speed with temperature finishing on battery just after finishing of charging process is in inverse proportion . after just battery The optimum point where the charging process speed accords with the temperature rise . on ( The battery's life is not shortened on this point . ) Temperature charging the Low Slow Fast Charging speed The electronic charging control system The ideal channel for temperature rise on battery The ideal channel for temperature rise is The temperature has to rise through the ideal channel programed in the electronic charging control system to get the optimum point . in advance to correspond to the various conditions . The charging time for Ni - MH . batteries The charging time for Ni - MH . batteries Charging may differ depending on the conditions time ( min . ) of batteries . The out put current for charge is to be limited Outside temperature : 20 ° C 40 to low level to protect the batteries in case of the following conditions . Consequently the charging 35 time may be longer than usual . * Charge for the batteries with low temperature 30 * Charge for the batteries with high temperature * Charge for the inactive batteries , which are new , : Ni - MH . 3.0Ah 25 however , not used for long period of time . : Ni - MH . 2.2Ah The charging time for such batteries is as follows . 2.2Ah batteries : approx . 30 min . under the 20 outside temperature , 25 ° C . 3.0Ah batteries : approx . 45 min . under the 15 outside temperature , 25 ° C . 0 ° C 10 ° C 20 ° C 30 ° C 40 ° C The temperature on battery However , they can be charged within normal time at the start of charging process from the next time . * Charge for the batteries just before ending of the life The charging time for battery 1233 ( 2.2Ah ) The charging time for such batteries is as follows . is approx . 20 minutes when the temperature on battery 2.2Ah batteries : approx . 30 min . under the is 25 ° C under the outside temperature , 20 ° C . outside temperature , 25 ° C . However , please note that the above figure can differ 3.0Ah batteries : approx . 45 min . under the from conditions to conditions . outside temperature , 25 ° C .

P 4 / 5 Repair < 1 > The charging circuit complete can not be repaired , because the circuit itself are molded on the board with the urethane resin . It has to be replaced as a charging circuit complete . < 2 > In case of damaged varistor or fuse , they can be repaired according to the following procedure without replacing the circuit board . ( 1 ) How to find broken varistor a . In case that the surface of varistor ( ref . to the following illustration ) has broken or has become black , and fuse has been cut , the varistor has been damaged . b . Varistor can be damaged easily , if the charger is plugged in a double voltage of the rating one . c . It is considered that the varistor has been broken for other reasons , if the fuse is broken while the surface of varistor is not damaged . In this case charging circuit complete has to be replaced . Fuse Varistor FOR 120 Varistor FOR 220 - 240V Charging circuit complete Fuse Receptacle Terminal Fig . 1A Fig . 1 ( 2 ) Removing broken varistor A . Cut the lead wire of varistor at the height of about 10mm from the surface of urethane resin . Fig . 2 Cut approx . by 10mm B . Take off lead wire's sheath by 2 - 3mm with nipper to expose the core . 2 - 3mm Fig . 3 ( 3 ) Assembling new Varistor ( See Fig . 3 ) a . Cut new varistor's lead wires to 10 mm , and insert them about 5mm depth between the sheath and the core . b . Solder both lead wires , being so careful that they may not contact with each other . Approx . 10mm Solder here . Insert about 5mm depth . Fig . 4

P 5 / 5 Repair ( 4 ) Replacing fuse for 220 - 240V ( See Fig . 1 . ) 1 . Remove damaged fuse from the receptacle , and replace the damaged one with new fuse . ( 4A ) Replacing fuse for 120 ( See Fig . 1A . ) 1 . Remove damaged fuse from terminal by melting the wire with soldering iron . 2 . Connect the wire of fuse to the terminal and solder the wire with the terminal . < Note > Be careful not to overheat the fuse with soldering iron . Otherwise the wire may be cut with the heat of soldering iron . 3 . Cut the surplus of wires with nipper .
