LED adierazleak
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.
- LED berdea distiratzen da poliki-poliki: Batteries are currently charging.
- Green LED illuminated (solid): Bateriak guztiz kargatuta daude.
- 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. Segurtasun Ezaugarriak
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.
- Temperature Interruption: Monitors battery temperature during charging and stops if overheating is detected.
- Primary Battery Protection: Prevents charging of non-rechargeable (disposable) batteries.
- Alderantzizko polaritatearen babesa: Protects against damage if batteries are inserted incorrectly.
- These features collectively prevent overcharging, over-voltage, short circuits, and help extend battery life.

5. Mantentzea
To ensure optimal performance and longevity of your GP RECYKO charger and batteries, follow these maintenance guidelines:
- Keep the charger and docking station clean and dry. Use a soft, dry cloth to wipe surfaces.
- Saihestu unitatea tenperatura altuen, eguzki-argiaren eraginpean edo hezetasun handiaren eraginpean jartzea.
- Kargagailua eta bateriak leku fresko eta lehor batean gorde erabiltzen ez dituzunean.
- Do not attempt to disassemble or modify the charger or docking station.
6. Arazoak
Kargagailuarekin arazoak badituzu, jarraitu arazoak konpontzeko ohiko urrats hauek:
- Batteries not charging / LED flashes fast:
- Ziurtatu bateriak polaritate zuzenarekin behar bezala sartuta daudela.
- 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.
- Kargagailua ez da pizten:
- Ziurtatu USB kablea kargagailura eta elikatze-iturrira ondo konektatuta dagoela.
- Try a different USB cable or power source to rule out a faulty component.
Arazoak jarraitzen badu, jarri harremanetan bezeroarentzako laguntza-zerbitzuarekin laguntza gehiago lortzeko.
