Setup
- Inspect the Cord: Before connecting, visually inspect the power cord for any signs of damage. Do not use if the cord or connector appears damaged.
- Locate Power Port: Identify the power input port on your Cobra XRS-979 or XRS-969 radar detector.
- Connect to Detector: Insert the barrel connector end of the onerbl power cord firmly into the radar detector's power input port.
- Connect to Vehicle Power: Insert the cigarette lighter adapter end of the power cord into your vehicle's 12V or 24V accessory power outlet (cigarette lighter socket).
- Verify Power: Once connected, your radar detector should power on or indicate power reception. If not, check connections and your vehicle's power outlet.
Operating Instructions
The onerbl replacement car power cord is designed for straightforward operation. Once properly connected as described in the Setup section, it provides continuous power to your compatible Cobra radar detector.
- Automatic Power: The power cord typically activates when your vehicle's ignition is turned on, supplying power to the radar detector.
- Power Off: When your vehicle's ignition is turned off, the power supply to the cord will cease, and the radar detector will power down (unless it has an internal battery or other power source).
- Safety Features: This power cord includes built-in protections against short-circuit, over-voltage, and over-current to safeguard your device and vehicle's electrical system.
