The power button is located on the back of the glasses, near the charging port, on the inner surface. You can feel it protruding slightly from the surface and it has a different texture. Don't confuse it with the circular Envision logo, which also protrudes, but is on the outside. The power button is the only physical button on the Envision Glasses and allows you to turn the Envision Glasses on and off, put them into sleep mode or resume them. Everything else is done with the touchpad on the side.
To power on your Envision Glasses, you can do so by holding the power button for 6 seconds. The power button is located on the rear end of the glasses, next to the charging port, on the inside surface. Please, be patient once you have pressed on it for 6 seconds, as it takes about a minute for the device to boot up, and there is no audio cue during this process.
For the first time, you will know that Envision Glasses are on when they speak out the start screen, which says 'Go to EnvisionGlasses.com', this simply means that your glasses are ready to be paired with your Envision App. For more information, see Pairing your Envision Glasses
Once you have paired Envision Glasses, you can also turn them on by unfolding them. This process is done automatically and can take between 20 seconds to 2 minutes, depending on usage, as the glasses need time to load all the preferences of the device. You know your Envision Glasses are on when you hear the word Home.
Note: Keep in mind that your Envision Glasses will automatically turn on when you unfold them and when you connect them to the power cable.
To turn off your Envision Glasses, press and hold the button for 3 seconds. You will hear a sound when the Envision Glasses initiate the power-off process, which completes in 20 seconds.
We recommend shutting down Envision Glasses if you are not going to use them for the next three hours. If you are going to use them in the next three hours, we recommend that you simply put them in Sleep Mode.
Keep in mind that your Envision Glasses will automatically turn on when you unfold them and when you connect them to the power cable even if you have already powered them off. We recommend that when you turn them off, you fold them up and put them in the protective case to ensure that the glasses will have battery power when you need them.
When the glasses are not being used, it is best to put them on sleep mode in order to conserve battery. There are different ways to set your device to sleep mode:
- Folding the glasses: The most convenient way to put your glasses to sleep is by folding the frame. The hinge sensor will detect that your glasses are folded in and it will set them to sleep mode. An audio cue is provided when the glasses are awake or set to sleep mode.
- Power button: By pressing once the power button, the device will go to sleep. This will happen both when the Envision Glasses are folded out and in.
- Home Screen: Go to Home and do a two-finger swipe down. The glasses will beep and that means they are now in Sleep Mode. Alternatively, if you are on the Home screen, it will automatically go to sleep after 30 seconds.
- Settings: Go to Settings and then select the Power option. The Sleep option will appear. Do a one-finger double tap to put them to sleep. The glasses will beep and that means they are now in Sleep Mode.
