These safety precautions are important to the safe operation of this product and should be observed at all times.

  • Page 3: Precautions Regarding Safety Safety Precautions

    Do not look into the laser radiation aperture directly as this may result in damage to your eyes. Never use the telescope to view intense light such as direct sunlight or sunlight reflected through a prism as this may result in loss of sight.
  • Page 4 PENTAX R-300 (p01-19) 10/30/02 PRECAUTIONS REGARDING SAFETY CAUTION For security, please do the opening inspection and inspection every a fixed period and adjustment. When the laser beam enters eyes, an unexpected accident might be caused by the blink of eyes. Establish the laser product to avoid the height of eyes of a driving person and walker.

  • Page 5: Usage Precautions

    [Solar Observation] WARNING Never view the sun directly using the telescope as this may result in loss of sight. Never point the objective lens directly at the sun as this may damage internal components. When using the instrument for solar observation, be sure to attach the special solar filter (MU64) designed for this product to the objective lens.
