If "Presentation Mode" is not available in the Unitech Scan Service Profile Management, your device may not be updated to the latest version. Follow these steps to ensure your device is updated to the latest versions of Android and all the bundled Unitech Apps. ### Update Android System | 🔋 | Make sure your device is **fully charged **and **plugged into the wall charger** before starting a system update to avoid any interruptions. | | --- | --- | Navigate to **System Settings > System > System Update Center** You should see the **Unitech SHEILD **logo at the top of the screen. Tap the **Refresh **icon in the top right of the page to check for updates. If there is an update available, download it and wait for the update to install. This process takes a few minutes. Your RT112 will reboot automatically after the update is complete. ### Update Unitech Apps Once your device has rebooted, tap on the purple **Software Update** button in the app drawer. Tap the **Refresh **icon in the top right of the page to check for updates. If any updates are available for the bundled Unitech apps, you can click the **Download All** button. ### Reset Scanner Profiles Tap on the blue **USS Profile Management** button in the app drawer. Tap the **Hamburger** icon in the top right of the screen and select **Factory Default**. This will reset your scanner profiles to defaults - it will not delete any data off your device. Once reset, tap the **Default **profile to open it. Tap on **Scanner Settings > Trigger Modes** and select **Presentation Mode.** - [VeriScan for Windows](https://support.idscan.net/veriscan-for-windows?hsLang=en#main-content) - [Scanning](https://support.idscan.net/veriscan-for-windows?hsLang=en#scanning) -
