Leitner Corded Compat Settings

Updated by Kamika Royal on May 19, 2024

Use this article as a guide to help you find the right settings for your phone.

The settings we need to change are a pair of small switches located on the bottom end of the headset (not the bottom of the quick disconnect cord).

Leitner corded headsets have two (2) compatibility switches where the cord for the headset snaps into the quick disconnect cord for your phone or computer. They are labeled 1-2 and 3-4. Use the tip of a pen to move the compatibility.
