fourth rechargeable batteries can be only set to charging at a maximum current of 700 mA.
Therefore, the user is advised to place the battery with the highest expected charging current in Compartment 1 first. To release the restriction of setting charging current, user must take out all four rechargeable batteries from the charging unit.
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.
When overheating conditions occur (over about 127°F (53°C)), usually due to too high a charging current selected), the charging will be stopped immediately and the display will read “000 mA”, the charging process will only resume once the temperature of the rechargeable batteries drops to a safe level. If overheating conditions continue to occur, the rechargeable batteries must be taken out to cool down and then charged at a lower current.
When the battery is overheated the charging will cease automatically. “000
16mA” will be displayed.
Note:
The discharging current is always set to be half of the coming charging current whose upper limit is 1000 mA (see Table 2). Therefore the user is recommended to carefully select the discharging current so that the charging current afterward will not be too high.
The mode key shall first be pressed and held for about 1 second to activate the mode change. The subsequent pressing of the mode key will toggle between the “Charge”, “Discharge”, “Test” and “Refresh” mode.

Finally, batteries will be fully charged in discharge mode and “Full” will be displayed. If the user presses the DISPLAY key at this time, "charge" icon instead of "discharge" icon will be

For a new rechargeable battery it is recommended to charge it with 200 mA current to
DISCHARGE MODE
Discharge mode will first discharge the rechargeable battery then charge it. It is for removing the memory effects of rechargeable batteries.
By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Discharge mode can be selected. Then the user may also select different discharging current (see Table 2) by pressing the CURRENT key, within 8 seconds after inserting the batteries. (The display will blink once to indicate the setting has been confirmed and the current cannot be changed afterward.)

displayed.
REFRESH MODE
Old rechargeable batteries and those that have not been used for a long time require refreshing. This process will recover the optimum capacity of the rechargeable batteries. By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Refresh mode can be selected.
Refresh mode will start with discharging the rechargeable battery, then charging it. The repeated discharging and charging cycles will be launched until no further increase in the measured capacities is estimated.
