Switch on the base by pressing the power button (LED will light red) and the

will light red). Now select the required vertical lines (V1, V2) and switch on the
receiving mode at the laser. Switch on receiver FR 57-M (see previous page); now

target point and press the AUTO button for automatic tracking; the instrument will

Automatic tracking function
Select the tracking direction (RIGHT or LEFT) with the arrow buttons. Now the
tracking procedure will start. When the laser line is in on-grade position a perma-
nent beep will sound and the centre LED will light green. In case the laser line
does detect the on-grade mark the procedure has failed and the receiver beeps
three times. Re-start the procedure by pressing AUTO again. When the laser line
is in on-grade position the tracking function automatically stops, i. e. for a new
on-grade position the procedure has to be started again by pressing AUTO. During
the tracking procedure a discontinued beep will sound; when the laser line is in
on-grade position a permanent beep will sound.
