## Questions & Answers

**Q: Camera stops when engine is off**
A: The yellow ACC wire senses ignition status to switch between driving and parking mode. If the mode doesn’t change, ensure the ACC wire is connected to an ignition-triggered circuit and parking mode is enabled on the menu.

**Q: Camera stops unexpectedly during parking mode**
A: This usually occurs if the battery reaches low-voltage cutoff or the parking timer ends.

**Q: Camera keeps recording after turning off the engine**
A: Confirm the ACC wire is correctly connected to an accessory circuit (not constant power).

**Q: How to install the dash cam hardwire kit?**
A: Connect the red wire to a constant power source using a fuse tap. Connect the yellow wire to a circuit that only has power when the ignition is on (ACC). Securely ground the black wire to an unpainted metal point.

**Q: Does hardwire cable have low voltage protection function?**
A: Yes, the hardwire kit features built-in low-voltage protection. It automatically cuts power to the dash cam when your vehicle's battery drops to 11.8V (for 12V systems) or 24.8V (for 24V systems), preventing battery drain.﻿

Good kit with a voltage selector but would be better if some fuse taps where provided for the install. Works great otherwise with my a229 pro
