KEEP THIS MANUAL IN A SAFE PLACE AS YOU MAY NEED TO USE IT AT A LATER DATE. We draw the attention of all users of this device: please follow the safety and maintenance instructions which are part of this manual. Also read the caution markings on the charger, the manual, and the gift box. 2 INTRODUCTION: Congratulations on purchasing this intelligent charging unit which enables quick and optimum charging to "AA" and "AAA" rechargeable batteries. [. . . ] By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Discharge mode can be selected. (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 enable to toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. ) Note: The discharging current is always set to be half of the coming charging current whose upper limit is 700 mA (see Table 2). Therefore user is recommended to carefully select the discharging current so that the charging current afterward will not be too high. DISCHARGE MODE Current User-selected Discharging 100 mA current Thereafter Charging 200 mA current 250 mA 500 mA 350 mA 700 mA 13 14 Finally batteries will be fully charged in discharge mode and "Full" will be displayed. If user presses DISPLAY key at this time, "charge" icon instead of "discharge" icon will be displayed. Note: By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Refresh mode can be selected. (The mode key shall first be pressed and held for about 5 seconds to activate the mode change. The subsequent pressing of the mode key will enable to toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. ) Then user may also select a different discharging current by pressing the CURRENT key (see "Note" in Discharge mode and Table 2), within 8 seconds after inserting the batteries. (Or the display will blink once to indicate the end of setting and the current cannot be changed afterward. ) It may take up to several days to finish the refreshing process, depending on the selected discharging current. The maximum refresh current is 350 mA. REFRESH MODE Old rechargeable batteries and those have not been used for a long time require refreshing. This mode is automatically launched after rechargeable batteries are fully charged and kept at the charging unit. The signal "Full" will be displayed on the LCD. 500 mA 250 mA 700 mA 350 mA 17 18 DISPLAY MODE INFORMATION User can use different display modes to monitor the rechargeable battery condition during the different operations (see below figure and Table 4 to 7). Different display modes are exhibited: Charging current, Time, Voltage and Capacity Table 4.

(For example, 1:45 will be shown after the battery has been refreshed for 21 hr and 45 min. ) 21 22 · In case the power source is shortly interrupted or terminated when the charger is being operated, the operational mode will automatically be set to "Charge mode at 200 mA" to charge up the battery once the power source is back to normal, regardless of the operating mode (Charge, Discharge, Refresh or Test) which has been selected by user before. SPECIFICATIONS: Input voltage for AC/DC adapter Charging current range Max charging capacity (capacity of rechargeable batteries) Dimensions (L x H x W) of Charging unit : : : : 100-240 VAC 200 mA - 700 mA 3000 mAh 2. 95" x 5. 11" x 1. 57" (75 x 130 x 40 mm) CARE AND MAINTENANCE: Extreme temperatures, vibration and shock should be avoided as these may cause damage to the unit When cleaning the displays and casings, use a soft damp cloth only. Do not wet the exposed metal part of the charging unit. Do not use solvents or scouring agents as they may mark the LCD and casing. Do not spill water to the charging unit. Do not make any repair attempts to the units. [. . . ] NiMH (Nickel Metal Hydride) or NiCd (Nickel Cadium) rechargeable batteries only may be used in this product. Charging other types of batteries may result in failure of the charger. This charger requires at least . 9v in the battery in order to charge it. If the battery is depleted below that point, you will not be able to charge it on this battery charger. [. . . ]
