Built-in Safety Features:
- Over Charge Protection: Prevents damage from excessive charging.
- Over Voltage Protection: Safeguards against voltage surges.
- Short-circuit Protection: Protects against electrical shorts.
- Over Current Protection: Prevents damage from excessive current flow.
- Over Temp Protection: Monitors and regulates internal temperature to prevent overheating.
Setup Instructions
- Inspect the Cable: Before use, visually inspect the power cord for any signs of damage or wear.
- Verify Compatibility: Ensure your Whistler Radar device (e.g., 1630, 1640De-1650, 1793SE) requires a 12V DC input and has a compatible power port. The power cord features a standard car cigarette lighter plug on one end and a DC barrel connector on the other.
- Connect to Device: Carefully insert the DC barrel connector end of the power cord into the power input port of your Whistler Radar device.
- Connect to Vehicle Power: Insert the car cigarette lighter plug end of the power cord into your vehicle's 12V accessory power outlet (cigarette lighter socket).
- Secure Connection: Ensure both connections are firm and secure.

Operating Instructions
Once the power cord is securely connected to both your Whistler Radar device and your vehicle's 12V accessory power outlet, the device should receive power. Most Whistler Radar devices will automatically power on or indicate power reception. Refer to your specific Whistler Radar device's manual for its power-on sequence and indicators.
- The power cord is designed for a DC12V input range.
- The cable length is approximately 50cm to 147cm (coiled to extended).

Care and Maintenance
- Cleaning: Disconnect the power cord from both the device and the vehicle before cleaning. Wipe with a dry, soft cloth. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, store the power cord in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Ventilation: If the adapter is used for extended periods, ensure it is in a well-ventilated area to prevent overheating.
- Handling: Always grasp the plug when connecting or disconnecting; do not pull on the cable itself.
Troubleshooting
If your device is not receiving power, consider the following:
- Check Connections: Ensure both ends of the power cord are securely plugged into the device and the vehicle's 12V accessory outlet.
- Vehicle Outlet Functionality: Verify that your vehicle's 12V accessory outlet is operational. Test it with another known working device if possible.
- Device Compatibility: Double-check that your Whistler Radar model is listed as compatible and requires a 12V input.
- Cable Damage: Inspect the power cord for any visible signs of damage, such as cuts, frayed wires, or bent connectors. If damaged, discontinue use and replace.
- Device Issue: If the power cord appears functional, the issue might be with the Whistler Radar device itself. Refer to its instruction manual.
