Warning
• Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
• Never intentionally point the laser beam at another person. The laser beam is injurious to the eyes and skin.
If an eye injury is caused by exposure to the laser beam, seek immediate medical attention from a licensed
ophthalmologist.
• The laser beam is emitted when the power is turned ON. Before turning the power on, make sure that
persons are not located in the path of the laser beam.
• Do not look directly into the laser beam. Doing so could cause permanent eye damage.
• Do not stare at the laser beam. Doing so could cause permanent eye damage.
• Aiming the instrument into prism or highly reflective surface can result in serious damage to your eye
because the optical axis and laser beam source is in coincidence. Do not aim the instrument directly into
prism or highly reflective surface. Do not look at the laser beam directly.
Caution
• Perform checks at start of work and periodic checks and adjustments with the laser beam emitted under
normal conditions.
• When the instrument is not being used, turn off the power and replace the lens cap.
• When disposing of the instrument, destroy the battery connector so that the laser beam cannot be emitted.
• Avoid setting the instrument at heights at which the path of the laser may strike pedestrians or drivers at head
height. Operate the instrument with due caution to avoid injuries that may be caused by the laser beam
unintentionally striking a person in the eye.
• Do not emit the laserbeam at eye level.
• Never point the laser beam at mirrors, windows or surfaces that are highly reflective. The reflected laser
beam could cause serious injury
• When using the laser-pointer function, be sure to turn OFF the output laser after measurement is completed.
Even if the power is turned off, the laser-pointer function is still operating and the laser beam continues to be
emitted.
