The Leica CS35 is a robust tablet designed for field use, running a customized version of Microsoft Windows with the Leica Captivate field software. This device serves as a control unit for Leica Geosystems' surveying equipment, including GNSS sensors, total stations, and multi-stations. Its primary function is to facilitate data collection, processing, and management in various surveying applications.

Function Description:

The CS35 tablet integrates a standard Microsoft Windows operating system with a specialized Leica Image, which includes tailored settings and essential software components. The Leica Image ensures optimal performance and compatibility with Leica Captivate, a comprehensive field software for surveying. Key components of the Leica Image include:

Special Leica Windows settings: These settings are optimized for field operations, encompassing desktop, start menu, and lock screen configurations, as well as digital keyboard functionality and the assignment of A1/A2 tablet button functions.
Hardware-specific drivers: The image includes necessary drivers for various hardware components, such as WWAN, ensuring seamless integration and operation of the tablet's features.
Leica Captivate: This is the core field software, providing a user-friendly interface for surveying tasks, data management, and instrument control. It supports a wide range of applications, including Survey and Stake Points, COGO Area Division, and more.
CLM (License Activation Tool): This tool, along with its activation wizards, manages software licenses and entitlements, ensuring that all purchased and trial applications are properly activated.
RadioHandle wizard: This wizard assists in configuring radio communication, crucial for connecting to and controlling surveying instruments wirelessly.
Recovery Partition content: A dedicated recovery partition is included to facilitate system restoration and maintenance, ensuring the tablet can be reset to its factory state if needed.

The CS35 is designed to be the central hub for surveying workflows, allowing users to control instruments, visualize data, and perform calculations directly in the field. Its ability to connect to Leica GNSS sensors, total stations, and multi-stations makes it a versatile tool for various surveying projects.

Usage Features:

The CS35 is delivered in a wizard mode, guiding the user through initial setup steps such as language selection, PC name, password configuration, and Windows settings. This ensures a smooth first-time experience.

Software Entitlement Activation: The device requires activation of two Entitlement IDs. The first ID activates purchased software licenses for Leica Captivate apps (e.g., Survey and Stake Points, COGO Area Division) and sets the Customer Care Package (CCP) end date. The second ID enables a 180-day trial period for apps not initially purchased, starting from the activation date. The activation process is guided by a wizard, which automatically displays the Entitlement ID if available, or allows manual entry from the invoice or delivery note.
Network Configuration: The Leica Image includes specific network configurations necessary for Leica Captivate, such as Bluetooth connectivity to GS (GNSS sensors). This ensures reliable communication between the tablet and surveying instruments.
User Interface: The tablet provides a user-friendly interface through Leica Captivate, allowing for intuitive control of surveying instruments and efficient data handling.
Connectivity: The CS35 supports connections to Leica GNSS sensors, total stations, and multi-stations, enabling comprehensive surveying operations. The detailed configuration and operation of these connections are described in the Leica Captivate Technical Reference Manual.

Maintenance Features:

While the CS35 runs a standard Microsoft Windows version, the Leica Image includes specific considerations for maintenance and system integrity.

Windows Updates: The Leica Image does not alter Windows update settings, meaning Windows updates are installed automatically. This ensures the operating system remains current and secure.
System Integrity: The proper operation of Leica Captivate is guaranteed only when changes to the image or operating system are limited to those recommended by Leica Geosystems. Users are advised to refer to the detailed safety directions in the available User Manuals for permitted product usage.
Software Installation: Users are allowed to install additional software. However, caution is advised regarding certain changes that might cause issues:
- Loading another, non-Leica image.
- Installing non-Leica provided drivers.
- Loading software that also uses the CLM license management but operates on a different version.
IT Infrastructure Integration: Bringing the CS35 into an IT infrastructure might automatically change network settings, potentially leading to issues with the Leica network settings. Users should be aware of this possibility and consult their IT department if necessary.
Support Limitations: Any support from Leica Geosystems after unauthorized changes to the system is limited, and the responsibility for such changes lies with the user or their IT department.
Troubleshooting Activation Issues: In case of license activation failures, users are directed to contact their local Leica Geosystems agency or create support requests on myWorld@Leica Geosystems for assistance.

The Leica CS35 is designed for reliability and ease of use in demanding field environments, with a focus on maintaining system stability through its customized Leica Image and clear guidelines for usage and maintenance.
