[. . . ] Looking directly into the laser beam ­ especially with optical light collecting instruments such as binoculars, etc. The laser viewing glasses serve for better recognition of the laser beam, however, they do not protect against the laser radiation. Do not use the laser viewing glasses as sun glasses or in street traffic. The laser viewing glasses do not provide complete UV protection and reduce colour perception. [. . . ] Use only batteries from a single manufacturer and with the same capacity. Before switching on, press the reel-in button 12 and completely rewind the measuring tape. Switching On/Off s When switched on, the instrument immediately emits a laser beam from the outlet opening 8. Do not direct the laser beam at persons or animals and do not look directly into the laser beam (especially not with optical instruments). Also 5/16") since a distance exists between the reference points for length measurement (16 and 17) even with the measuring tape completely rewound. The error message shown here appears if the instrument is switched on when the measuring tape 10 is not rewound. 5 min without performing a measurement, the instrument switches off automatically to save the batteries. ) After switching on the measuring instrument, the measured values are shown in the unit that was selected the last time the measuring instrument was used. By repeated pressing of the button for changing the measuring unit 4 with a pointed object, a change can be made at any time between the measuring units of centimetres and feet/inches. Laser Viewing Glasses (Accessory) The laser viewing glasses filter out the ambient light. as a result , the red light of the laser appears brighter to the eye. S The laser viewing glasses (accessory) are not protective glasses against laser radiation. Do not use them as protective glasses against strong sun light or in traffic. A ) The instrument measures the distance d between the lower case edge (reference point 16) and the outer notch on the marking opening (reference point 17). For the horizontal alignment of the laser beam, use the bubble level 7, for the vertical alignment, the bubble level 6. for alignment to existing markings , place the instrument on the marking with the notch under the laser outlet (reference point 18). S The horizontal or the vertical path of the laser beam can be determined exclusively with the bubble levels 6 or 7. The placing of the case against horizontal or vertical surfaces does not ensure parallelism of the laser beam to these reference lines. [. . . ] Batteries Do not throw batteries into the household waste, fire or water. batteries should be collected , recycled or disposed of in an environmentally friendly manner. Only for EU countries According to the Guidelines 91/157/EEC, defective or used batteries must be recycled. Batteries/rechargeable batteries that are no longer useable can be sent directly to: Great Britain Robert Bosch Ltd. [. . . ]
