START CHARGING THE RECHARGEABLE BATTERIES
Once a rechargeable battery is inserted after the transformer has been plugged into 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 alteration 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. “Charge”, “Discharge”, “Refresh” and “Test” mode
may be chosen.
Then within 8 seconds from the last key pressing, user may select the charging/
discharging current by pressing the CURRENT key.
Note:
 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.
 There is an 8-second time allowed for choosing further functions after each key
pressing. If no more keys are pressed, the LCD will blink one time to indicate the end of
13
setting. Afterward, the current can no longer be changed during the process and the
selected mode will begin.
Charging current: 200 mA
Charge Mode
After 8 seconds from the last key
press, the LCD will blink once to
indicate the setting is confirmed and
the selected mode is 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).
After the rechargeable battery is fully charged, “Full” will be shown on the display and the user
may take out them at this time. If the rechargeable batteries are left in place in the
compartments, trickle charging will start. The trickle charging current is around 5% of the
selected charging current to keep the rechargeable batteries full.

Note :
 The current cannot be altered once the setting has been confirmed in the initial stage.
This prevents the user from changing the current setting accidentally while setting other
rechargeable batteries. If one wants to change the applied current afterward, the
rechargeable batteries must be taken out and inserted again.
 The maximum charging current of the other rechargeable batteries is restricted by the
current setting of the first inserted rechargeable battery. For instance, if the first
inserted rechargeable battery is set to charge at 700 mA, then the second, third and
“Full” sign is shown -The battery
is fully charged
