Button Operations

Button Overview

Each side has two buttons, front and rear. For reliable response and tactile feedback during sports, we use physical buttons. The front button has a raised dot. You need to remember the front and rear operations, and it becomes very intuitive once you get used to it.

Quick Disconnect & Power Off

Quick Disconnect

Double-press the rear button of the right side to disconnect, and double-press again to reconnect. The glasses will turn off automatically 3 minutes after being disconnected from the phone, which makes it convenient to use as a quick power-off feature.

Push-to-Talk

Push-to-Talk

Download Zello and open the "Add Hardware Button" page. Turn on the glasses — they will appear in the list as "PTT-Z01". Hold the rear button (on either side) to talk, and release to send.

Zello

You need to download Zello on your iPhone or Android phone to use the Push-to-Talk feature. You're not limited to talking between the glasses—you can talk to any phone or device that uses Zello. Download on App Store or Download on Google Play.
