Note:
User shall always observe the recommended maximum charging current of the
rechargeable batteries. In general, 200 mA is a recommended charging current if rapid
charging is not necessary. It is definitely safe and optimum to the rechargeable batteries.
It may be necessary to charge and discharge the new rechargeable batteries for several
time in the beginning before the optimum capacity of the rechargeable batteries can be
obtained. User is recommended to perform the "Refresh" mode to new rechargeable
batteries in order to achieve optimum battery capacity.
When the transformer has been plugged to the power source, the version number of the
charger (for example "29" ) will be displayed first. Then all the segments will light up
momentarily and the "null" sign will be shown before batteries are placed. If damaged
batteries are placed to the charging unit, the charger will also show "null" on LCD.
START CHARGING THE RECHARGEABLE BATTERIES
Once a rechargeable battery is inserted after the transformer has been plugged to the power
source, the battery voltage (for example, "1.39V") will be displayed for 4 seconds. Then "200
mA Charge" (default mode) will be shown on LCD for another 4 seconds, indicating that
charging with 200 mA is to be started if no alternation in setting is made.
Within this 8-second time from inserting the batteries the user may first select the
operating mode by the MODE key.
Then within 8 seconds from the last key pressing, user may select the charging/
discharging current by pressing the CURRENT key.
