For Your Safety Working safely with this unit is possible only when the operating and safety information are read com- pletely and the instructions contained therein are strictly followed. Laser radiation of laser class 2 630–675 nm, <1 mW, according to EN 60825-1:2001 The instrument complies with 21CFR, Parts 1040.10 and 1040.11.
Putting into Operation Switching On/Off Switching on: Press the “on/off” button 6 or the measurement button 7 completely down. Switching off: Press the “on/off” button 6. After approx. 5 min without performing a measurement, the unit switches off automatically to save the batteries. With the automatic switch-off, the current display and the settings of the unit are also stored in addition to the already stored measured values.
Continuous Pointer Mode As required, the unit can be switched to continuous laser beam (continuous pointer mode). For this purpose, press the measurement button 7 lightly in the middle or the side to switch on the laser beam. Then press the contin- uous pointer mode button 10.
Changing the End Piece The unit is provided with two different end pieces. The compact end piece 17 reduces the dimensions of the unit. It is suit- able for measurements for which the rear end of the unit can rest on a flat surface.

Area Measurement Press the area measuring button 5 to switch to the mode for area measuring. The symbol for area measurements appears in the upper part of the display. Then measure the length and width one after the other as for a length measurement. After completing the second measurement, the re- sult is automatically calculated and displayed.

Minimum-Maximum Measurement (see Fig. The minimum/maximum measurement serves to determine the minimum or maximum distance from a fixed reference point. It is an aid, for exam- ple, for the determination of diagonals (maximum value) as well as verti- cals and horizontals (minimum value). To switch to the minimum/maximum measuring mode, press the button 1.

Subtraction from Measured Values By pressing the button 15, the value at the bottom of the display is deducted from the value stored. In the display, “M–” appears briefly and then “M”. If a value is already present in the memory, the new value is subtracted from the memory contents, however, only when the units of measurement are in agreement (see Storing/Adding of Measured Values).

Maintenance Do not immerse the unit in water. Wipe off dirt with a damp, soft cloth. Do not use aggressive cleaning agents or solvents. Take care of the unit, especially the receiving lens 22, by handling it in the same manner as for eye glasses or a camera. If the unit should fail despite the care taken in manufacture and testing, the repair should be performed by an authorized Trimble Service Center.
