AUTOMATIC TRACKING FUNCTION

(Available for vertical laser lines only)
The automatic tracking function is ony effective together with receiver FR 57-M.
For the axis-alignment:
Position the laser over the ground point
Postion on-grade-mark of receiver FR 57-M at the target point
Activate receiver FR 57-M
The closest vertical laser line moves to the on-grade-position of the receiver auto-
matically
The receiver FR 57-M can also be used as:
Normal receiver detecting the horizontal/vertical laser lines
Remote control to operate the horizontal movement manually
The FR 57-M receives the laser line signal from the instrument and sends out an
infrared remote command to the instrument base. The base rotates until the laser
line is exactly centered to the on-grade position of the receiver. (Range: 30 m).
Switch on the receiver by pressing button 2. A long beep will sound and the LEDs
on the left side of the receiving window will flash one after the other (top = red,
middle = green, bottom = yellow). Now the receiver is in receiving mode and
the sound is in low volume. Press button 2 again to switch off the receiver. Three
short beeps will sound.
