Device Information

Device Care

NOTICE

Do not store the device where prolonged exposure to extreme temperatures can occur, because it can cause 
permanent damage.
Avoid chemical cleaners, solvents, sunscreen, and insect repellents that can damage plastic components and 
finishes.
Secure the weather cap tightly to prevent damage to the USB port.
Avoid extreme shock and harsh treatment, because it can degrade the life of the product.

Cleaning the Device

NOTICE

Do not use a cloth or any material that can scratch the optical lens on the front of the device. Scratching the 
optical lens may cause poor radar performance.

• Clear mud and dirt from the weather cap area.
• While the weather cap is closed, hold the device under running water.
After cleaning, allow the device to dry completely.

Radar Detection

 WARNING

The device can improve situational awareness. It is not a replacement for cyclist attentiveness and good 
judgement. Always maintain awareness of your surroundings, and operate the bicycle in a safe manner. Failure 

to do so could result in serious injury or death.

• The radar detects approaching vehicles up to 140 m away.
• The radar detects approaching vehicle speed from 10 to 160 km/h (from 6 to 99 mph).

NOTE: The radar does not detect vehicles traveling at the same speed as your bike.

• The radar beam width is 40 degrees. It provides radar coverage for typical bends in the road.
• The radar can detect up to eight approaching vehicles.
