Introduction
WARNING
See the Important Safety and Product Information guide in the product box for product warnings and other important information.
The device can improve situational awareness. It is not a replacement for cyclist attentiveness and good judgement. Always use your best judgment, and operate the bicycle in a
safe manner.
Getting Started
You can use the Varia RTL (radar taillight) with the Varia RDU (radar display unit) or with your compatible Edge® device. This list provides an overview of the installation and
setup tasks.
Charge the device (Charging the Device, page 3).
Install the taillight on your bike seat post using one of the included mounts:
Install the universal mount (Installing the Universal Mount, page 1).
Install the seat-post mount (Installing the Seat-Post Mount, page 1).
If you are using the Varia RDU, install it on your bike stem or handlebar (Installing the Varia RDU Device, page 2).
NOTE: When you purchase the Varia RTL and RDU devices together, they are already paired.
If you are using a compatible Edge device, pair the devices (Pairing the Taillight with Your Edge 1000, page 3).
Tips for Installing the Taillight
The Varia RTL device includes a taillight and micro radar that can detect approaching vehicles up to 140 meters away.
Select a secure location to mount the device where it does not interfere with the safe operation of your bike.
Select a mount that best fits your bike.
Mount the device as high on the seat post as possible for optimal light visibility and radar detection. NOTE: The mount surface should be vertical.
Install the device correctly. The device faces backward and is parallel to the road. The Garmin® logo is right-side up.
Go for a test ride during the day in a safe environment
