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.
In case one of the arrow keys (left or right) is used during the tracking procedure same will re-start
from the beginning.
Note:
If the laser line is already in the receiving window of the receiver and an arrow button is used the
tracking direction of the base will change.
In order to save battery power the base can be powered off when the tracking procedure is finished.
Note:
If the instrument is not operated for more than 10 minutes the base will automatically power off (in
order to save battery power).
MANUAL OPERATION
The rotation can also be controlled manually. The receiver is then used as a remote control.
Press the AUTO button to power off the automatic tracking function. Now the base can be rotated
with the right or left arrow button. Holding down the arrow keys for a longer time increases the
rotation speed of the base.
