Why does the headset turn off after 30 minutes when it has not been moved, docked, or used?

To conserve battery, the headset will automatically turn off when it has not been docked for 30 minutes, moved, or used.

To end the Power Nap, either move the headset (the headset has built-in motion sensors), press any button on the headset, or dock the headset in the base.

You can turn off/on the Power Nap setting using Jabra Direct.
