Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is dim or unreadable. | Unit not connected to power, or poor visibility in direct sunlight. | Ensure the car charger is securely plugged into the cigarette lighter. Reposition the unit to avoid direct, harsh sunlight if possible. |
| Temperature readings are inaccurate. | External sensor improperly placed (e.g., near engine heat, direct sun) or damaged. | Relocate the external sensor to an area away from heat sources and direct sunlight. Check the sensor cable for damage. |
| Settings are lost when vehicle power is off. | This unit may not have internal memory retention when disconnected from continuous power. | This is expected behavior for some models. Re-set time/date upon reconnecting power if necessary. |
| Voltage alarm sounds frequently. | Vehicle battery voltage is consistently too high or too low. | Consult a vehicle technician to check your car's electrical system and battery health. |
