Updating the Software on the dēzl Headset 100 and dēzl Headset 200

The dēzl™ Headset 100 and dēzl™ Headset 200 Premium Trucking Headsets can only be updated using the dēzl™ App.

NOTE: Do not turn off the headset while an update is installing.

When an update is available, the dēzl™ app sends it to the headset automatically.
The next time you start your headset, it notifies you that it is installing an update.
Or, you can start the update manually in the dēzl™ app:

During the update, the Power LED light on the headset will stay illuminated.
The update takes a couple moments and the headset won't function while updating.
A progress bar will show in the dēzl™ app during the update.
After the update is complete, each LED light on the headset will illuminate, then the headset restarts and operates normally.

See dēzl™ App Software Versions for a list of software releases and how to check the current dēzl™ App version installed.
