Go to **SETTINGS**, then press down and turn the selector knob to see each setting option. When done, long press to return to the **SETTINGS **screen**.** ### Installing the Zello app and creating an account Since the device doesn't have a screen, you'll need to use a computer to configure it. 1. Download an Android remote control application to your computer. For example, [Vysor](https://vysor.io/) is one such app that works on both Mac and Windows PCs.  **NOTE**: Zello is not affiliated with, nor endorsing, Vysor 2. Connect the TE390 to your computer using a USB cable 3. Use Vysor to configure the device and download Zello for Android from the [Zello website](https://zello.com/downloads/android/) 4. You may be prompted to allow apps from unknown sources to be installed. Tap **SETTINGS\>OK** and turn on the **Unknown sources** setting to allow the installation to proceed. ![](https://support.zello.com/hs-fs/hubfs/Knowledge%20Base%20Import/27652558940557-2.png?width=300&height=546&name=27652558940557-2.png)      ![](https://support.zello.com/hs-fs/hubfs/Knowledge%20Base%20Import/27652558950797-2.png?width=300&height=547&name=27652558950797-2.png) 5. On the homescreen, go to **File Manager**, locate the Zello .apk file, and click on it to install Zello 6. Tap **OPEN** to open Zello in Vysor  7. If you do not have a Zello account, create one now. If you already have an account, log in with the account username 8. You should see **RECENTS** in the OLED screen on top. ### Creating Zello channels and contacts Channels and/or contacts can be mapped to your device's selector knob by following the instructions [outlined here.](https://paidsupport.zello.com/hc/en-us/articles/28236147249037-Hardware-Knob-Mode-Configuration)  ### Mapping the push-to-talk button and secondary buttons The Telo TE390 is pre-mapped for Zello PTT and ZelloWork Emergency Alerts. No additional mapping is required.  ### Using Zello with the selector knob The TE390 radio includes a knob (with no stop or markings) that allows you to switch through all your contacts and channels. There is no limit on the number of contacts or channels you can access on the selector knob. To switch between different Zello screens (RECENTS, CHANNEL, CONTACTS), push the knob down. Turn the knob to scroll down through your recents/channels/contacts. When done, push down to cycle through your screens again.  - [Getting Started](https://support.zello.com/zw/getting-started?hsLang=en#main-content) - [Trials](https://support.zello.com/zw/getting-started?hsLang=en#trials) - [Admins](https://support.zello.com/zw/getting-started?hsLang=en#admins) - [Users](https://support.zello.com/zw/getting-started?hsLang=en#users) - [Dispatch Hub](https://support.zello.com/zw/getting-started?hsLang=en#dispatch-hub) - [Intro to Zello](https://support.zello.com/zw/getting-started?hsLang=en#intro-to-zello) - [Admins](https://support.zello.com/zw/admins?hsLang=en#main-content) - [User Management](https://support.zello.com/zw/admins?hsLang=en#user-management) - [Channels](https://support.zello.com/zw/admins?hsLang=en#channels) - [Dispatch Hub](https://support.zello.com/zw/admins?hsLang=en#dispatch-hub) - [Network Settings and Configurations](https://support.zello.com/zw/admins?hsLang=en#network-settings-and-configurations) - [Zello Enterprise Server](https://support.zello.com/zw/admins?hsLang=en#zello-enterprise-server) - [Payments, Subscriptions, and Billing](https://support.zello.com/zw/admins?hsLang=en#payments-subscriptions-and-billing) - [Using Zello](https://support.zello.com/zw/using-zello?hsLang=en#main-content) - [Dispatch Hub](https://support.zello.com/zw/using-zello?hsLang=en#dispatch-hub) - [User Communications](https://support.zello.com/zw/using-zello?hsLang=en#user-communications) - [Channels](https://support.zello.com/zw/using-zello?hsLang=en#channels) - [Settings](https://support.zello.com/zw/using-zello?hsLang=en#settings) - [Features](https://support.zello.com/zw/using-zello?hsLang=en#features) - [Windows PC App](https://support.zello.com/zw/using-zello?hsLang=en#windows-pc-app) - [Accessories](https://support.zello.com/zw/accessories?hsLang=en#main-content) - [Rugged/Specialized Phones](https://support.zello.com/zw/accessories?hsLang=en#rugged-specialized-phones) - [Network Radios](https://support.zello.com/zw/accessories?hsLang=en#network-radios) - [Headsets](https://support.zello.com/zw/accessories?hsLang=en#headsets) - [Speakers/Mics](https://support.zello.com/zw/accessories?hsLang=en#speakers-mics) - [Wireless Buttons](https://support.zello.com/zw/accessories?hsLang=en#wireless-buttons) - [Gateways](https://support.zello.com/zw/accessories?hsLang=en#gateways) - [Partners & Developers](https://support.zello.com/zw/partners-developers?hsLang=en#main-content) - [Partnerships](https://support.zello.com/zw/partners-developers?hsLang=en#partnerships) - [New Mobile SDK (iOS, Android, React Native)](https://support.zello.com/zw/partners-developers?hsLang=en#new-mobile-sdk-ios-android-react-native) - [Legacy SDK (Android-Only)](https://support.zello.com/zw/partners-developers?hsLang=en#legacy-sdk-android-only) - [API and Integrations](https://support.zello.com/zw/partners-developers?hsLang=en#api-and-integrations) - [FAQ](https://support.zello.com/zw/faq?hsLang=en#main-content) - [Functionality](https://support.zello.com/zw/faq?hsLang=en#functionality) - [Accessories](https://support.zello.com/zw/faq?hsLang=en#accessories) - [Troubleshooting](https://support.zello.com/zw/faq?hsLang=en#troubleshooting) - [Network](https://support.zello.com/zw/faq?hsLang=en#network) - [Compliance](https://support.zello.com/zw/faq?hsLang=en#compliance) - [Videos](https://support.zello.com/zw/videos?hsLang=en#main-content) - [Android](https://support.zello.com/zw/videos?hsLang=en#android) - [Management Console](https://support.zello.com/zw/videos?hsLang=en#management-console) - [iOS](https://support.zello.com/zw/videos?hsLang=en#ios) - [Channels](https://support.zello.com/zw/videos?hsLang=en#channels) - [Dispatch Hub](https://support.zello.com/zw/videos?hsLang=en#dispatch-hub) [![wordmark@2x](https://support.zello.com/hs-fs/hubfs/2024%20Trial%20series/wordmark@2x.png?width=92&height=16&name=wordmark@2x.png "wordmark@2x")](https://zello.com) Zello Inc Help Center Copyright © 2025, Zello
