Maintenance Tips

• Clean Optics Carefully: Use a soft, lint-free cloth to wipe the telescope lens, eyepiece, and electronic display; avoid solvents or abrasive materials.

• Protect from Impact: Store the theodolite in its hard case after use to prevent bumps, drops, or vibration damage.

• Battery Maintenance: Use only recommended batteries; recharge or replace as needed, and remove batteries if storing for long periods.

• Check Leveling and Calibration: Periodically verify horizontal and vertical accuracy, especially after transport or rough handling.

• Avoid Moisture Exposure: Keep the instrument dry; wipe off any condensation immediately to prevent internal damage.

• Handle Tripod Carefully: Ensure tripod mounting screws and clamps are secure to maintain stable measurements.

• Operate in Recommended Conditions: Avoid extreme temperatures, direct sunlight on the optics, or dusty environments without protection.
