1. MAINTENANCE AND SAFETY
• While the instrument is operating, be careful not to expose your eyes to the laser beam. Direct expo-
sure to a laser beam for a long time may be hazardous to your eyes. The laser beam is equivalent to a
class 2M (and class 3R for LS.RHVG only).
• Operate this laser so that the laser beam plane avoids impact on the eyes of vehicle drivers or pedes-
trians.
• Do not try to dismantle the instrument. Have it repaired by your dealer or supplier. Dismantling yourself
may worsen the problem or void your warranty.
• When attaching the instrument to a tripod, make sure the instrument is securely fixed. The tripod leg
clamps should be securely fastened. If not securely fastened or tightened, the main unit could fall off or
the tripod could fall over.
• The laser should not be stored or used in extreme temperature or during rapid temperature change.
The laser may not function properly if used out of the ambient temperature range.
• Store inside the carry case and place in a dry area not subject to vibration, dust or high moisture.
• If the storage temperature and ambient temperature for usage vary significantly, leave the laser in its
case until it can adjust to the ambient temperature.
• The laser should be transported or carried carefully to avoid impact or vibration.
• The laser should be stored in the carry case and packed with cushioning material. Always handle the
laser with care.
