With the supplied alcohol wipe, clean the vehicle surface where the LMU will be installed, ensuring to choose a
dry location with easy access to the electrical panel and cable connections.
The LMU contains a built-in GPS antenna, which can be obstructed by metal objects. The best place to mount
the LMU for optimal GPS reception is on top of the front dash panel, with the label facing out towards the sky.

Once you connect the harness, you’ll need to verify whether the device is powered and communicating with
the Safe Fleet Cloud servers. The following table describes the LED patterns on the LMU. Ensure that the
device reaches solid orange and solid green before moving onto the next step.
Once all of your devices are installed, powered, and communicating properly, you’ll need to provision the
devices with Safe Fleet software. A detailed walk-through of the provisioning procedure can be found on our
Safe Fleet Community customer support portal. Open a web browser on your device and navigate to
community.safefleet.net/installer
. Then, select the LMU provisioning procedure and follow the instructions
outlined on that page.
