User Guide

Introduction

Thank you for choosing the Spectra Precision® Laser Receiver HR220 from
the Trimble® family of precision instruments. The HR220 is a battery-operated
laser receiver that detects a pulsed line laser beam and indicates its position
relative to the beam using an LCD and simultaneous LEDs.

Before using the receiver, be sure to read this user guide carefully. Included in
it is information about setting up, using, and maintaining the receiver. Also
included in this manual are CAUTIONS and Notes. Each of these words
represents a level of danger or concern. A CAUTION indicates a hazard or
unsafe practice that could result in minor injury or property damage. A Note
indicates important information unrelated to safety.
