2. Opsætning
Follow these steps to set up your NITECORE USN4 PRO charger:
- Pak opladeren ud: Carefully remove the USN4 PRO charger and the included USB-C charging cable from its packaging.
- Tilslut strøm: Insert the USB-C charging cable into the input port of the USN4 PRO charger. Connect the other end of the cable to a USB power source (e.g., USB adapter, portable power bank, or solar panel) that provides DC 5V/2A or 9V/2A output.
- Indsæt batterier: Gently slide your Sony NP-FZ100 batteries into the designated charging slots (Slot 1 and Slot 2) on the USN4 PRO. Ensure the batteries are inserted correctly according to the polarity indicators.
3. Betjeningsvejledning
The USN4 PRO features an intelligent charging management system that automatically adopts optimal charging modes (Constant Current - CC and Constant Voltage - CV) based on battery status.
3.1 Opladningsproces
- Once a battery is inserted and power is connected, the USN4 PRO will initiate charging.
- The high-definition LCD display will show real-time charging information for each slot.
Displayet viser:
- Batteriets sundhed: Good, Normal, or Poor.
- Ladestrøm: Current flow into the battery.
- Charged Volume: Total mAh charged.
- Batteri Voltage: Nuværende voltage af batteriet.
- Batteriniveau: Visual representation of charge status.
3.2 Charging Modes and Output
- QC Mode (Quick Charge): When connected to a 9V power source, the charger can output up to 1200mA (MAX) for a single slot or 800mA (MAX) for two slots simultaneously. This allows for fast charging, capable of fully charging two batteries in approximately 4 hours.
- Standardtilstand: With a 5V power source, the charger provides up to 1000mA (MAX) for a single slot.
3.3 Over-Discharged Battery Activation
The USN4 PRO can automatically activate over-discharged batteries that have been caused by improper storage or misuse. This function is available for batteries equipped with a protection board.
3.4 Sikkerhedsfunktioner
- Omvendt polaritetsbeskyttelse: The charger features mechanical reverse polarity protection. If an incompatible battery is inserted or a battery is inserted incorrectly, the charging process will not initiate, preventing damage.
- Anti-Short Circuit Protection: Built-in mechanisms protect against short circuits.
- Cooling Fins Design: Unique cooling fins are designed to dissipate heat rapidly, preventing overheating during charging.
4. Vedligeholdelse
To ensure the longevity and optimal performance of your NITECORE USN4 PRO charger:
- Hold opladeren ren og fri for støv og snavs. Brug en blød, tør klud til rengøring.
- Opbevar opladeren på et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Undgå at tabe opladeren eller udsætte den for kraftige stød.
- Do not attempt to disassemble or modify the charger, as this will void the warranty and could cause damage.
5. Fejlfinding
If you encounter issues with your USN4 PRO charger, consider the following:
- Charger not turning on or not charging:
- Sørg for, at USB-C-kablet er korrekt tilsluttet til både opladeren og strømkilden.
- Verify that the power source is providing sufficient power (DC 5V/2A or 9V/2A).
- Check if the battery is inserted correctly according to polarity. The charger has reverse polarity protection and will not charge if inserted incorrectly.
- Langsom opladning:
- Ensure you are using a QC 2.0 compatible power adapter (9V output) to achieve fast charging speeds. A standard 5V USB adapter will result in slower charging.
- LCD displays "Poor" battery health:
- Remove the battery and re-insert it. If the "Poor" status persists consistently, the battery may be at the end of its lifespan and should be replaced.
The LCD display indicates battery health as Good, Normal, or Poor. - Opladeren føles varm under drift:
- It is normal for the charger to become slightly warm during charging due to the energy conversion process. The unique cooling fins design helps manage heat. If it becomes excessively hot, disconnect power immediately and contact support.
