Simple Setup & Operation Guide
1. Instrument Setup
- Place the tripod firmly over the survey point.
- Attach the R-322N to the tripod and secure the locking screw.
- Turn on the laser plummet and adjust the tripod legs to center the laser on the point.
- Level the instrument using the circular and electronic vials.
2. Basic Measurement
- Power on the instrument; it initializes automatically (no need for angle reset).
- Use the telescope to sight the target (prism or reflectorless surface).
- Press the MEAS key to start distance and angle measurement.
- View results on the dual displays; save data to internal memory.
3. Maintenance Tips
- Store in a dry, temperature-controlled environment when not in use.
- Keep the lens clean with a soft, dry cloth; avoid harsh chemicals.
- Charge the battery fully before long-term storage; recharge every 3 months.
- Transport in the original hard case to prevent damage.
