Using the Trek CarBack Rear Bike Radar Light is easy. First, pair it with your GPS head - unit following the instructions in the user manual. Once paired, turn on the light and it will start detecting approaching vehicles automatically. When a vehicle is detected within 240 meters, you'll get audio and visual alerts. As for maintenance, keep the light clean by wiping it with a soft, dry cloth regularly. Avoid exposing it to extreme temperatures or water for long periods. If you notice any issues with the radar or the light, check the battery level and make sure it's properly charged. Replace the battery as needed according to the manufacturer's recommendations. Always follow local traffic laws when using the light on the road.
