Scher-Khan Auto is a mobile application developed by LLC Mega-F for controlling car security systems, specifically Scher-Khan Universe 1,2,3,4, and Scher-Khan Mobicar 2, B, 3, 3 Pro. The app allows users to use their mobile device as an additional key fob and identification tag (except for Universe) using Bluetooth Smart wireless connection. By using a smartphone with the app installed, users can conveniently manage and configure various system features, as well as diagnose and receive information about the security system's operation modes. The app also allows users to manage the Scher-Khan security system, configure security system options, configure the schedule and conditions for engine startup, and scan engine diagnostic codes. Additionally, the app displays alarm zones, settings levels of alarm sensors and their status, engine and interior temperature (if the temperature sensor is located in the cabin), the exact value of the engine speed, voltage on-board network, fuel level, and vehicle speed. Scher-Khan Auto is a free mobile app available on Android and provides a quick reference to use the security system.
