Therefore, user is recommend to place the battery with the highest expected charging 
current at Compartment 1 first. To release the restriction of setting charging current, 
user shall take out all four rechargeable batteries from the charging unit.     

z

 

To change the operating mode during charging, one can press the MODE key (for 
selecting all rechargeable batteries) or NUMBER key then MODE key (for selecting 
individual rechargeable battery). 8 seconds after the last key press the LCD will blink 
one time to indicate the end of changing. 

z

 

When overheating condition occurs (over about 53°C, usually due to too high a 
charging current selected), the charging will be stopped immediately and the display 
will shown “000 mA”, the charging process will only resume once the temperature of 
the rechargeable batteries drops to a safe level. If overheat conditions continue to 
occur, the rechargeable batteries shall be taken out to cool down and then charged at 
a lower current. 

 

When the battery is overheated the 
charging will ceases automatically. 
“000 mA” will be displayed.
