User manual LA CROSSE TECHNOLOGY RS1000

[. . . ] Never use any power cable and transformer other than those originally supplied with the charging unit. The rechargeable batteries may become hot during charging (especially when high charging current is chosen). User shall take extra care when taking out the batteries after charging. 5. 6. FEATURES: The Charging unit Charging rechargeable battery in various current (200, 500, 700 or 1000 mA). [. . . ] 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 4 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 enable to toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. There is a 8-second time allowed for choosing further functions after each key pressing. If no more key is pressed, the LCD will blink one time to indicate the end of setting. Afterward, the current can no longer be changed during the process and the selected mode will be undergone. 45 After 8 seconds from no more keys pressing, the LCD will blink once to indicate the setting is confirmed and the selected mode activated Charging current: 200 mA Charge Mode 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" sign will be shown on the display and the user may take out them at this time. Or if the rechargeable batteries are kept placing at the compartments, trickle charging will start. The trickle charging current is around 5% of the selected charging current to keep the rechargeable batteries being full. 46 "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. If one wants to change the applied current afterward, the rechargeable batteries must be taken out and inserted again. The maximum charging current of other rechargeable batteries are 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 fourth rechargeable batteries can be only set to charging at a maximum current of 700 mA. 47 Therefore, user is recommend to place the battery with the highest expected charging current at Compartment 1 first. To release the restriction of setting charging current, user shall 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 condition occurs (over about 53° usually due to too high a charging C, current selected), the charging will be stopped immediately for all channels charging and discharging, and the display will shown "000 mA", the charging process will only resume once the temperature of the rechargeable batteries drops to a safe level. If overheat conditions continue to occur, the rechargeable batteries shall be taken out to cool down and then charged at a lower current. When the battery is overheated the charging will ceases automatically for ALL channels. "000 mA" will be displayed. 48 For new rechargeable battery it is recommended to charge it with 200 mA current for reconditioning it from the long storage status. [. . . ] Return it to its original point of purchase for repair by a qualified engineer. Do not expose the unit to extreme and sudden temperature changes, this may lead to damage to the electronic parts in the unit. 63 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 - 1800 mA 3000 mAh 75 x 129 x 37. 2 mm LIABILITY DISCLAIMER: The manufacturer and supplier cannot accept any responsibility for any improper or incorrect use and any consequences occur.
