The TCR805 uses an infrared EDM optimized for a -30mm or -17.5mm prism constant (depending on your Leica circular prism). The manual contains a critical warning: Never use a standard GPR1 prism constant for long-range work without checking the offset table. It also explains the RL (Reflectorless) mode—a premium feature for its time—and the maximum distance to various surfaces (concrete, wood, uncoated steel).

The TCR805 interface relies on a combination of physical keys and on-screen softkeys. The manual provides a clear map of the System Menu, showing you how to:

Unlike modern touchscreen robotic total stations, the Leica TCR805 operates with a soft-key interface and a 4-line alphanumeric display.
