Refer to the LED display touch screen or the mobile app (for Bluetooth versions) to adjust this setting.
6. Operating Instructions
6.1 Powering On/Off and Temperature Control
Use the LED Display Touch Screen to power on/off the unit and set the desired temperature. The temperature range is -20℃ to 20℃ (-4℉ to 68℉).
6.2 Fast Cooling and ECO Mode
- Fast Cooling: The powerful compressor allows the refrigerator to cool down below 0°C (32°F) in approximately 15 minutes. In MAX mode, it can reach -20°C (-4°F) in less than 4 hours.
- ECO Mode: For energy efficiency, activate ECO mode. This mode optimizes power consumption, using approximately 0.18kWh per day.

6.3 Dual-Zone System
The refrigerator features a removable partition, allowing you to create two separate temperature zones:
- Use the partition to maintain a cooling zone (e.g., for drinks at 5°C) and a freezing zone (e.g., for meat at -18°C) simultaneously.
- Remove the partition to create a single, large compartment for larger items.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Refrigerator not turning on | No power supply; loose connection; vehicle battery low. | Check power cords and connections. Ensure vehicle battery has sufficient charge. Adjust battery protection level to 'L' if necessary, but monitor vehicle battery. |
| Not cooling sufficiently | Temperature setting too high; ventilation blocked; excessive ambient temperature; door not sealed properly. | Lower temperature setting. Ensure clear ventilation. Avoid direct sunlight. Check door seal for obstructions. |
| Unusual noise | Unit not level; fan obstruction. | Ensure the unit is on a stable, level surface. Check for any obstructions around the fan. (Normal operating noise is ≤45 dB). |
| App connection issues | Bluetooth not enabled; app not updated; incorrect pairing. | Ensure Bluetooth is enabled on your device. Update the app to the latest version. Follow app instructions for pairing. |
9. User Tips
- Pre-cool before travel: For optimal performance, pre-cool the refrigerator at home using AC power before loading it with items and heading out.
