Nga korero haumaru
WHAKATOKANGA: Panuitia nga whakatupato me nga tohutohu haumaru katoa. Ki te kore e whai i nga whakatupato me nga tohutohu ka puta pea te ru hiko, te ahi, me te whara kino/ranei.
- Me whakahaere i nga wa katoa te rihi i roto i te waahi pai-hau.
- Avoid sparks, flames, or smoking near the battery during charging, as batteries can produce explosive gases.
- Mau kakahu whakamarumaru kanohi me nga kakahu whakamarumaru ina mahi me nga pākahiko.
- Disconnect the AC power supply before making or breaking connections to the battery.
- This charger is designed for 6V and 12V lead-acid batteries only. Do not use it to charge dry-cell batteries that are commonly used with home appliances, as these may burst and cause injury to persons and damage to property.
- Keep the charger and its components out of reach of children.
- The charger has an IP64 water-resistant rating, meaning it is protected from dust and splashing water. It is not designed to be submerged in water.

Nga Tohutohu Whakahaere
The CJ TECH charger operates automatically once connected to a battery and power source.
- Aunoa Voltage Raputanga: The charger will automatically detect if the connected battery is 6V or 12V. It requires an activation voltage of 4V for 6V batteries and 8V for 12V batteries to begin charging.
- Aratau Whakatau: When the battery is charging, the LED Whero will illuminate. The charger delivers a constant current of 0.75A ±0.1A during this phase.
- Maintenance (Float) Mode: Once the battery reaches full charge, the charger automatically switches to maintenance mode, and the LED Koura will illuminate. In this mode, the charger provides a small, continuous current to keep the battery at optimal charge without overcharging, preventing sulfation and extending battery life.
- Momotu: To disconnect the charger, first unplug it from the AC power outlet, then disconnect the negative (-) battery connector, followed by the positive (+) battery connector.
