    those have not been used for a long times, refreshing may bring the rechargeable battery back to the optimum condition. Check the rechargeable battery capacity in mAh/ Ah (TEST) CHARGE MODE Charging at 200 mA is the default-operating mode of the charging unit. User may select a charging current of 200, 500 or 700 mA.
  • Page 8 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 times in the beginning before the optimum capacity of the rechargeable batteries can be obtained.
  • Page 9 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.
  • Page 10 Charging current: 200 mA After 8 seconds from no more keys pressing, the LCD will blink once to indicate the setting is confirmed and Charge Mode the selected mode activated During charging, the different displays- Charging current (in mA), Time elapsed (in hh:mm), Terminal voltage (in V) and Accumulated capacities (in mAh or Ah) may be toggled and selected by pressing the DISPLAY key (refer Table 4).
  • Page 11 “Full” sign is shown -The battery is fully charged Note : The current cannot be altered once the setting has been confirmed in the initial stage. This can avoid the user changing the current setting accidentally while doing setting on other rechargeable batteries.
