5. Návod k obsluze
Follow these steps to charge your batteries:
- Vložte baterie: Carefully insert one or more compatible rechargeable batteries into the charging slots, ensuring correct polarity (+ and - ends match the markings on the charger). The charger will automatically detect the battery type (Li-ion 3.7V, Ni-MH/Cd 1.2V) and begin charging. For LiFePO4 3.2V and Li-ion 3.8V (IMR) batteries, manual selection may be required using the corresponding slot button.
- Nabíjení monitoru: The LCD display will show real-time charging information, including:
- Battery type (e.g., NiMH/NiCd-1.2V, LiFePO4-3.2V, Li-ion-3.80V, Li-ion-3.70V)
- Procento nabíjenítage (%)
- Accumulated charge (mAh)
- Aktuální svtage (V)
- Doba nabíjení (h)
- Charging current (CH-CURRENT: 500mA, 1000mA, 2000mA)
- Nabíjecí proud: The charger intelligently auto-sets the current. Note that the 2000mA charging current is exclusively available for slot #4 when it is the only slot in use. If multiple slots are used, the current will adjust accordingly (e.g., 1000mA for two batteries, 500mA for three or four).
- Dokončení: Charging is complete when the LCD display shows "End" for the respective slot and the battery percentage reaches 100%. Remove batteries promptly after charging is complete.
