# FAQs – Hardwire Kit

### **Q1. How do I choose the correct fuse holder for my vehicle?**

**A.** Since fuse types vary by vehicle, follow these steps:

- Check your **vehicle’s owner’s manual** for fuse box location and fuse type.
- Remove one of the existing fuses and visually compare it to the included fuse holders.
- Choose from the supported types: **Micro2 / Micro3 / Mini / ATO / Low-profile Mini (LPM)**.
- Match the fuse holder based on shape and pin spacing for a secure fit.

> 💡 Using the wrong fuse holder may result in power failure or damage to the dashcam.

### **Q2. My dashcam is not turning on. What should I check?**

**A.** Please follow these troubleshooting steps:

1. Verify that the **ACC (red)** and **BATT (yellow)** wires are connected to the correct fuse slots.
2. Check if the **fuse is blown** and replace it if needed.
3. Make sure the **GND (black)** wire is securely grounded to a bare metal bolt on the vehicle chassis.
4. Confirm that the hardwire cable is **firmly connected** to the dashcam’s power port.
5. If still not working, try another fuse slot with the same characteristics.

### **Q3. Parking Mode is not working.**

**A.** Please confirm the following:

- The ACC wire is connected to a **fuse that only receives power when ignition is ON**.
- If unsure, test with a **multimeter** to confirm switched vs. constant power.
- Go to your dashcam’s settings menu and make sure **Parking Mode is enabled**.
- Ensure that **motion or impact detection** settings are also turned on.

> 🔧 You may also use Power Magic Pro or an external battery to control Parking Mode power settings more precisely.

### **Q4. My car battery drains after extended parking.**

**A.** Since the dashcam continues operating even when the vehicle is turned off, extended parking periods may lead to battery drain. To prevent this, we recommend the following:

- Use a **BlackVue external battery (B-130A)** to supply power to the dashcam independently, reducing load on the vehicle’s main battery.
- Alternatively, enable the **Power Saving Mode** in your dashcam settings. This feature minimizes power consumption during Parking Mode by entering standby and only recording when an event (motion or impact) is detected.
- Some models also support **low-voltage cutoff**, which automatically turns off the dashcam if the vehicle battery drops below a preset threshold.

> 🔋 For those who frequently use Parking Mode for long durations, combining an external battery with power-saving features is highly recommended for safe and efficient operation.
