- F04: Over-temperature protection
- F05: Over-time charging
- F06: Reverse connection protection
Troubleshooting
If the charger does not react when powered on, check the mains connection and power supply. If an icon is permanently displayed, check for incorrect polarity. If an icon is flashing, check the battery connections and cables for damage. Note that charging modes can only be selected when the battery is not connected.
Maintenance
Disconnect from the power supply before performing any maintenance. Use a dry cloth to wipe battery corrosion, dirt, or oil from the connectors, cords, and charger case. Ensure all components are in good working condition. Servicing does not require opening the unit as there are no user-serviceable parts. Store the charger in a cool, dry place when not in use.
