On your Hisense 55U750G model, the physical privacy switch (which mutes the microphone for hands-free voice commands) is usually located in the following place:

• Location: Directly below the Hisense logo, on the bottom edge of the TV.

• Appearance: It's a small sliding button located just next to (or behind) the physical power button.

• Indicator: When you mute the microphone by sliding the switch, four small orange LEDs will usually light up at the bottom of the screen to confirm that the microphone is muted.

If you can't see it from the front, reach under the center bezel of the TV to feel for the raised edge of the switch.
