Check

1. Jethro is on. Turn it over and check that the power switch is on ON.
2. Jethro is charged. Plug in the cable from the box for a while. See Charge Jethro.
3. Jethro is connected. The light on the bottom shows the connection: red for the USB receiver, blue for wireless connection 1, purple for wireless connection 2. Press the button next to it to switch.
4. The Virtusx app is open and you are signed in. Without the app, the Mic key, Translate key and AI key do nothing, and Jethro works as a regular mouse.
5. On a Mac, Virtusx is allowed. Open System Settings, then Privacy & Security, and turn on Virtusx under Microphone and Accessibility.
6. Hold or click. Hold the Mic key to dictate and click it to record a meeting. Hold the Translate key to translate and click it for the Smart Toolbar. Hold the AI key to ask and click it to open the app.
