The X-Series BTECH Mobiles introduce our new fully customizable Multi-Color LCD display screen. You can adjust the complete display to be exactly as you want it (with 9 available colors across 10 display elements). Beyond the display, you can fully customize your channels to display their alpha-numeric names or frequency settings.  <br><br> The X-Series Mobiles also introduces our new dual sync mode! With this option, you can single or dual sync two different channels and display both their frequency and name simultaneously. If you prefer instead to monitor up to four channels; you can single line display a channel's name or frequency. Additionally, as a new feature added: you can even monitor both VFO (frequency) and channel modes simultaneously. <br><br> Another feature introduced in the X-Series mobiles is the ability to edit your channel preferences without needing to program a new channel! You can edit tones, additional squelch information, and even add or remove it from your scanning list anytime! <br><br> Scanning channels and frequencies has now gotten even easier! A new menu allows you to select scanning resume methods. You can set the radio to start scanning immediately during reboot, resume scanning if you interrupt scanning to transmit, or start scanning soon as it powers on. The UV-50X2 will save your scanning preferences even with a power interruption. Frequency scanning has gotten a full overhaul; you can edit and scan through frequencies exactly as you prefer. Set your frequency range and frequency interval (step) right through the UV-50X2 on-screen interface. <br><br> You can adjust the Microphone Gain with the in-menu audio adjustments. The X-Series Mobiles include a 3.5mm Line In/Line Out multi-jack to allow remote audio input and output.
