2. Información de seguridade
Observe as seguintes precaucións de seguridade para evitar lesións ou danos no produto:
- Use this charger exclusively for NiMH rechargeable batteries. Do not attempt to charge alkaline, NiCd, or Li-ion batteries, as this may cause damage, leakage, or explosion.
- Ensure batteries are inserted with correct polarity (+/-) as indicated on the charger and batteries. Incorrect insertion can lead to damage.
- Non desmonte, modifique nin provoque curtocircuítos no cargador nin nas baterías.
- Avoid exposing the charger or batteries to water, fire, extreme temperatures, or direct sunlight.
- Manter fóra do alcance dos nenos.
- If a battery shows signs of leakage, discoloration, deformation, or any other abnormality, discontinue use immediately.
- Always replace all batteries in a device simultaneously. Mixing old and new batteries, or different types of batteries, can reduce performance and potentially cause leakage.
- Consult your device's manual for specific battery requirements and compatibility with 1.2V NiMH batteries. Note that 1.2V NiMH batteries may have a shorter runtime than 1.5V alkaline batteries in some devices.
- NiMH batteries are slightly larger than alkaline batteries to meet IEC standards. Verify proper fit in your device.

5.2 Guía de indicadores LED
The charger features LED indicators for each slot to display the charging status:
| Estado LED | Descrición |
|---|---|
| Startup & Quick Diagnostic | When connected to power, all 4 LEDs light up briefly (1-2 seconds) and then turn off. |
| Slow Flashing (Charging) | A slow flash (approximately one flash per second) indicates that the battery in the slot is currently charging. |
| Solid White (Fully Charged) | A solid white light (no flashing) indicates that the battery in the slot is fully charged. The charger will then switch to a trickle charge mode to maintain the battery's charge. |
| Rapid Flashing (Error) | Rapid flashing (approximately two flashes per second) indicates an error. This could be due to a defective battery, an alkaline battery inserted, or incorrect polarity. Remove the battery and check. |

7 Solución de problemas
If you encounter issues with your charger or batteries, refer to the following:
- Batteries not charging (Rapid Flashing LED):
- Ensure the battery is a NiMH rechargeable type. The charger is not compatible with alkaline or other battery chemistries.
- Check for correct battery polarity. Reinsert the battery, ensuring the '+' and '-' terminals align with the charger's markings.
- The battery may be defective. Try charging a different NiMH battery to confirm charger functionality.
- Slow charging or reduced battery life:
- Ensure the charger is plugged directly into a functional wall outlet.
- Batteries have a limited number of charge cycles. If batteries are very old or have been recharged many times, their capacity may naturally decrease.
- Ensure the batteries are fully discharged before recharging for optimal performance, though NiMH batteries do not suffer from a "memory effect" as severely as NiCd.
- O cargador non se acende:
- Verifica que a toma de corrente funcione conectando outro dispositivo.
- Ensure the charger is securely plugged into the outlet.
