BATTERY STATUS

If the lamp (2) besides button „P" (2) is blinking the batteries have to be replaced.
NOTE:
During transport the base no. 3 must be set to position „LOCK" . Disregard may lead to damage of the
compensator.
USE WITH RECEIVER (OPTIONAL)
To prolong the working range or at unfavourable light conditions FL 40-3Liner (HP) can be used with the
optional receiver (not included in this kit).
Press button „P" (operating lamp besides the button is illuminated) to
change to the receiver mode. The receiver can now detect the signal
of FL 40-3Liner (HP) (the visibility of the laser lines is weaker in this mode).
The working range can be extended up to 60 meters by use of the
receiver. More detailed information you will find in the user manual
FR 55-M
of the receiver.

ACCURACY CHECK

Set up the instrument in the middle of two walls which are about 5 m apart. Mark a visible laser cross
on one wall. Turn the unit to the opposite wall and a mark laser cross.
Repeat the measurements with distances of about 0,6 m to one wall and about 4,4 m to the second
wall. A deviation between the two measurements taken from the centre and the two measurements
taken at 0,6 m and 4,4 m must not exceed 3 mm.
Accuracy check of the horizontal line (end to end)
Set up the instrument about 5 m from a wall. Mark a laser cross on the wall. Turn the instrument until
the laser cross has moved about 2,5 m to the left side and check if the horizontal line is within ± 2 mm
of laser cross marked on wall. Repeat the measurement by turning instrument to the right side .
Accuracy check of the vertical line (end to end)
Set up the instrument about 5 m from a wall. Fix a plumb line of 2,5 m length to the wall, using a plumb
bob. Bring the laser line into coincidence with the plumb line. A deviation between the laser line and
the plummet cord from the top to the bottom must not exceed ± 1,5 mm.
