1. Measurement precision, accuracy, reliability and time for initialisation are dependent
upon various factors including angular and distance accuracy of the total station,
target type, atmospheric conditions, target height and level of pole tilt.
2. Free line of sight to target required
3. Using radio handle RH18 or CCD18, connected to CS20 with internal LR-BT
4. Requires total station with target lock functionality and radio handle RH18 or CCD18
5. Requires total station with PowerSearch functionality
6. Metric scale
7. Feet scale
* 0.228 m refers to height with CRP10 attached to GRZ122
