6. Інструкція з експлуатації

Вставте батареї: Insert one or more compatible rechargeable batteries into the charging slots. Ensure correct polarity (+ and -) as indicated on the charger and battery. The charger will automatically detect the battery type and capacity.
Automatic Charging Mode Selection: The Ci4 will automatically select the appropriate charging mode (CC, CV, or -dV/dt) based on the detected battery type (Li-ion, Ni-MH, Ni-Cd).
Процес зарядки: The indicator lights above each slot will show the charging status.
- Red Indicator Constant-on: Indicates Fast Charge Mode.
- Green Indicators:
  - 3 Green Indicators Constant-on: 100% charged.
  - 2 Green Indicators Constant-on: Approximately 80% charged.
  - 1 Green Indicator Constant-on: Approximately 30% charged.
Over-Discharged Li-ion Battery Activation: If an over-discharged Li-ion battery with a protective circuit is inserted, the Ci4 is capable of attempting to activate it.
Завершення зарядки: The charger will automatically terminate charging once the batteries are fully charged. Remove the batteries from the slots.

9. Вирішення проблем

проблема	Можлива причина	Рішення
Зарядний пристрій не вмикається.	No power supply, faulty cable, or faulty adapter.	Ensure the USB-C cable is securely connected. Try a different USB-C cable or power adapter. Verify the power source is active.
Акумулятор не заряджається.	Incorrect battery insertion, incompatible battery, or deeply discharged battery.	Check battery polarity. Ensure the battery type is compatible with the Ci4. For deeply discharged Li-ion batteries, the charger will attempt activation; if unsuccessful, the battery may be faulty.
Зарядний пристрій або акумулятор надмірно нагріваються.	Poor ventilation, faulty battery, or environmental factors.	Ensure adequate ventilation around the charger. Remove the battery immediately. Do not use a battery that overheats. Contact support if the charger itself overheats without a battery.
Indicator lights behave unexpectedly.	Internal error or battery issue.	Remove all batteries and unplug the charger. Plug it back in and reinsert batteries. If the issue persists, contact customer support.
