6. Arahan Operasi
6.1. Pemilihan Jenis Bateri
Tekan ke "SELECT" button on the charger to cycle through and choose the appropriate battery type for your auxiliary battery (AGM, Gel, Calcium, Lead Acid, or LiFePO4). The selected battery type will be indicated by an illuminated LED.
6.2. Reverse Charging Function
To activate reverse charging and revive a flat start battery from your auxiliary battery, press the "REVERSE CHARGE" button. This feature ensures your starter battery remains charged for off-road use.

6.3. DC Charging Priority
The charger is configured with DC charging priority. When both the vehicle's start battery (DC input) and solar panels are connected and meet the startup conditions, the charger will prioritize the vehicle battery input. If solar charging is already active, the system will continuously monitor the DC input and automatically switch to DC power if conditions are met.
- Startup Conditions:
- Input DC: 13-24V
- Solar Input: 13-26V

- Check all connections for proper seating and polarity.
- Inspect fuses/breakers for continuity.
- Ensure the ACC ignition wire (if used) is receiving power when the vehicle is running.
- Output Pengecasan Rendah:
- Confirm the correct battery type is selected on the charger.
- Semak voltage drop in wiring due to undersized cables or long runs.
- Ensure solar panels are clean and receiving adequate sunlight if solar charging is active.
- Verify the alternator is functioning correctly and providing sufficient voltage.
- Terlalu panas:
- Ensure the charger is installed in a location with sufficient airflow.
- Remove any obstructions around the cooling fins.
- Reduce load if possible, or ensure the charger is not operating beyond its rated capacity.
If the issue persists after performing these checks, contact ATEM POWER customer support.
