Normally, applications are installed from our App Store as described [here](https://vuzix.document360.io/preview/v1/en/84b3bd72-9d77-4f92-8b55-a3c5021b5005/1). However, if you have downloaded an .apk file to your computer, you can install it via a USB connection. There are two mechanisms for this. Without Additional Software 1. For the M300XL: Disconnect the battery from the M300XL to expose the USB Micro-B port. For the M300: Attach either a USB Micro-B adapter or the a battery to the custom connector to expose the USB Micro-B port. 2. Insert a USB-A to USB Micro-B cable between the device and a USB-3.1 high-power port on the computer. Standard USB ports on the computer do not supply sufficient power and cannot be used. 3. On the M-Series device, open Settings > Storage & USB. 4. Long-press the front button to show the menu. 5. Select USB Mode. 6. Change the mode to File transfers. The M300 should appear as a device on your computer. 7. Use your Windows File Explorer or macOS Finder to copy the .apk file to the virtual SD Card of the device. 8. On the M-Series device, open Settings > Storage & USB > explore. 9. Locate the file you copied. 10. Highlight the .apk file and click it to install. Using Android Debug Bridge Software If not already installed, obtain ADB software from [developer.android.com](http://developer.android.com). Follow the setup procedure so that adb is in your path. Simply issue the command ‘adb install .apk’ in a command window.
