Installing the Device

To ensure maximum tail light visibility and radar detection range, you should install the mount according to these considerations.

Make sure the device does not interfere with the safe operation of your bike.
Install the mount as high as possible on the bike.
Mount the device 250 to 1200 mm above the road.
Mount the Varia™ RearVue 820 device parallel to the longitudinal axis of the vehicle.
Make sure there are no obstructions in front of the light.
Make sure the mount surface is perpendicular to the road.
Make sure the device faces straight back, so that the radar beam covers the maximum range behind your bike.

You should go for a test ride during the day, in a safe environment, and adjust the mount, if necessary, before using the tail light at night.
