3 PRECA UTIONS REGARDING SAFET Y Safety precautions (Must be follow ed) The following it ems are intended to prev ent possible injur y t o the user or other people and/or damage to the instrument before it occurs . These safety precautions are important to the safe operation of this pr oduct and should be obser ved at all times .
4 PRECA UTIONS REGARDING SAFET Y W ARNING Do not stare into the laser beam directly as this may result in damage to y our eyes. R-300X is a Class II Laser product. ( The reflectorless type is a Class IIIa (3R) laser product.) Do not look into the laser radiation aperture directly as this may result in damage to your eyes.
5 PRECA UTIONS REGARDING SAFET Y CA UTION F or security , please do the opening inspection and inspec tion every a fixed period and adjustment. When the laser beam enters eyes , an unexpec ted accident might be caused by the blink of eyes. E stablish the laser product to avoid the height of ey es of a driving person and walker .
6 PRECA UTIONS REGARDING SAFET Y Usage precautions Surveying instruments are high-precision instruments. In order to assure that the Electronic T otal Station R-300X series product which you have purchased will provide long-lasting maximum performance, the precautions in this manual must be followed .
7 PRECA UTIONS REGARDING SAFET Y • There is a possibility that the instrument cannot calculate correctly when receiving reflected laser beam from forth and back directions in case of measuring the target on the road.
8 PRECA UTIONS REGARDING SAFET Y [Storage and opera ting envir onment] • T o prevent making shor t-circuit when removing the battery and charger from the case and storing them, apply electrically resistant tape to the poles of the battery . Storing the battery and charger as is may result in fire or burn injury due to shor t-circuit.
