Starting operation
u Protect the laser receiver against mois-
ture and direct sunlight.
u Do not subject the laser receiver to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the laser
receiver to adjust to the ambient tempera-
ture before putting it into operation. In case
of extreme temperatures or variations in
temperature, the accuracy of the laser re-
ceiver can be impaired.
Setting up the laser receiver (see figure A)
Position the laser receiver so that the laser
beam can reach the reception area (1). Align
it so that the laser beam runs straight through
the reception area (as shown in the figure).
For rotary lasers with multiple operating
modes, select the horizontal or vertical opera-
tion with the highest rotational speed.
Switching On/Off
u A loud audio signal sounds when switch-
ing on the laser receiver. Therefore, keep
the laser receiver away from your ear or
other persons when switching it on. The
loud sound can damage hearing.
To switch on the laser receiver, press the
on/off button (19). All display indicators and
all LEDs light up briefly and an audio signal
sounds.
To switch off the laser receiver, press and
hold the on/off button (19) until all LEDs
briefly light up and the display goes out. All
settings are saved upon switching off. Except
the display backlight setting. It is always on
when turning the receiver on.
If no button on the laser receiver is pressed
for approx. 10 min and no laser beam reaches
the reception area (1) for 10 min, then the la-
ser receiver will automatically switch itself off
to preserve battery life.
Connection to the rotary laser (only with
GRL4000-80)
In the default factory setting, the rotary laser
and the supplied laser receiver are already
connected via Bluetooth®. For the existing
connection, the Bluetooth® connection indi-
cator (b) appears in the display of the laser
receiver.

Operation
In order to reconnect the laser receiver or
connect another laser receiver with the rotary
laser, start the connection setup on the rotary
laser. To do this, consult the operating in-
structions for the rotary laser. Then press the
X-axis button (16) and the Y-axis button (15)
on the laser receiver at the same time for five
seconds. Confirmation as to whether a con-
nection has successfully been established will
be shown on the display of the rotary laser.
If the connection between the rotary laser
and the laser receiver cannot be established,
PNK will appear in the text display (e) of the
laser receiver. For troubleshooting, consult
the operating instructions for the rotary laser.
Direction indicators
The position of the laser beam in the recep-
tion area (1) is indicated as follows:
– On the display (5) on the front and rear of
the laser receiver by means of the "laser
beam below center line" direction indica-
tor (f), the "laser beam above center line"
direction indicator (j) and the center line
indicator (h)
– Optionally, by means of the red "laser beam
below center line" LED direction indicator
(4), the blue "laser beam above center line"
LED direction indicator (2) and the green
center line LED (3) on the front of the laser
receiver
– By an audio signal (optional).
On the first pass of the laser beam through
the reception area (1) a short audio signal al-
ways sounds and the red "laser beam below
center line" LED direction indicator (4) and
the blue "laser beam above center line" LED
direction indicator (2) briefly light up (even if
the audio signal and/or LED direction indica-
tors have been switched off).
Laser receiver too low: If the laser beam hits
the upper half of the reception area (1), then
the "laser beam above center line" direction
indicator (j) appears in the display. If the
LEDs are switched on, the blue "laser beam
above center line" LED direction indicator (2)
lights up. If the audio signal is switched on, a
signal sounds in a slow rhythm.
Move the laser receiver upwards in the di-
rection of the arrow. When the laser beam is
close to the center line, only the tip of the "la-
ser beam above center line" direction indica-
tor (j) is shown.
