Headset connection type: RJ-9, USB. Android OS 9. Integrated dual-band Wi-Fi and Bluetooth. Easy installation thanks to PoE. This network-capable device is powered via the LAN cable using Power over Ethernet (PoE). The main advantage of PoE is that you do not need a power supply cable. This allows you to install Ethernet-connected devices in hard-to-reach places or in areas where many cables would be disruptive. You save on installation costs and can increase the reliability of connected devices by using a central uninterruptible power supply (UPS) if desired. Navigate elegantly and efficiently thanks to the touchscreen. Find phone numbers, addresses, and notes in no time and quickly move through the menu structure to change your device settings: the integrated touchscreen greatly simplifies all of this. It facilitates both navigation and an overview of stored information, thus enhancing your efficiency. Moreover, the device looks professional and operates elegantly with the touchscreen and without paper inserts.
