## Description

TechAssistant 2.0 gives certified service technicians instant access to RATIONAL service information on the go. It supports iCombi Pro, iCombi Classic, iVario, SelfCookingCenter, CombiMaster Plus, and VarioCookingCenter, with login via your RATIONAL ID. The app serves as your central Home overview with global search, device-specific data, and a multifunction scanner that uses QR codes and barcodes to jump to devices, parts, and password options.

Documentation includes training materials, installation instructions, technical information, conversion guides, case-specific videos, and service references. Use PINs and password management, and navigate with the bottom Tab Bar (Home, Favorites, Cart, More) to access new documents, saved content, and notifications from RATIONAL.
