ЛЕД индикатори
The LED display provides visual feedback on the charging status and battery condition:
- Green LED on for 0.5 seconds after USB power connection: Indicates the charger has received power.
- Зелени ЛЕД полако трепери: Batteries are currently charging.
- Green LED illuminated (solid): Батерије су потпуно напуњене.
- Green LED flashes fast: Indicates defective batteries or disposable batteries have been inserted.

Battery Status Check Function
The charger includes a function to quickly check the battery status. This allows you to determine if your batteries are sufficiently charged or require recharging, helping to avoid unexpected situations with empty batteries and unnecessary charging.
4. Сигурносне карактеристике
The GP B441 charger incorporates multiple safety mechanisms to protect both the batteries and the user:
- Automatic Shut Off Timer: Prevents overcharging. The timer is 5 hours when using 1 channel or 10 hours when using 2 channels.
- Full Charge Detection (-DV): Automatically detects when batteries are fully charged and stops the charging process.
- Прекид температуре: Monitors battery temperature during charging and stops if overheating is detected.
- Примарна заштита батерије: Prevents charging of non-rechargeable (disposable) batteries.
- Заштита од обрнутог поларитета: Protects against damage if batteries are inserted incorrectly.
- These features collectively prevent overcharging, over-voltage, short circuits, and help extend battery life.

КСНУМКС. Решавање проблема
Ако наиђете на проблеме са пуњачем, погледајте следеће уобичајене кораке за решавање проблема:
- Batteries not charging / LED flashes fast:
- Ensure batteries are correctly inserted with the correct polarity.
- Verify that the batteries are NiMH rechargeable type. The fast flashing green LED indicates that defective or disposable batteries have been inserted.
- Check the USB cable connection and ensure the power source is providing sufficient power (DC 5V/1A minimum).
- Try charging fewer batteries at a time to see if the issue persists.
- Пуњач се не укључује:
- Уверите се да је USB кабл безбедно повезан и са пуњачем и са извором напајања.
- Испробајте други УСБ кабл или извор напајања да бисте искључили неисправну компоненту.
Ако проблеми и даље постоје, контактирајте корисничку подршку за даљу помоћ.
