This unit is listen only. Listener units are a cost-effective way to add people into your conversation who need to hear it. If you are looking to add another full unit to your group, you need the two-way version.
When ordering, select the appropriate region for use. Please note that the model of the listener unit and regular unit must match to be compatible. A single group can have unlimited listeners.
