Laser Safety: Class 1 laser is eye-safe for general use, but never aim the laser directly at eyes or stare at the objective lens when emitting laser. Avoid aiming at strong light sources .
Battery Care: Use the built-in rechargeable Li-ion battery with included USB cable. Avoid over-discharging to prolong battery life .
Lens Cleaning: Keep lenses clean using a soft, dry cloth. Avoid touching optical surfaces with fingers.
Environmental Limits: Operate within -10°C to 50°C; avoid extreme temperatures and humidity. In rain, snow, or fog, measurement accuracy may be affected .
Storage: Store in a dry, ventilated place when not in use. Remove from extreme temperatures.
Avoid Strong Light Sources: Do not look at the sun or other strong light sources through the telescope to prevent eye damage .
Calibration Check: Regularly check calibration against known distances; contact support if accuracy seems off .
