Display Illumination - Bosch LR 60 Professional Notice Originale

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. With the exception of the setting for the display
lighting, all settings are saved when the laser receiver is
switched off.
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 laser receiver will automatically switch it-
self off to preserve battery life.
Connection to the Rotary Laser
In the default factory setting, the rotary laser and the sup-
plied laser receiver are already connected via Bluetooth®.
For the existing connection, the Bluetooth® connection
indicator (b) appears in the display of the laser receiver.
To reconnect the laser receiver or to connect an additional
laser receiver with the rotary laser, press and hold the
Bluetooth® button on the rotary laser until the symbol for es-
tablishing a connection to the remote control/laser receiver
appears in the display of the rotary laser. Then press and
hold the X‑axis button (16) and Y‑axis button (15) on the
laser receiver until P‑‑ appears in the text display (e).
Confirmation as to whether a connection has successfully
been established will be shown on the display of the rotary
laser. POK will appear on the text indicator (e) of the laser
receiver.
If the connection between the rotary laser and the laser re-
ceiver cannot be established, PNK will appear in the text
display (e) of the laser receiver and the error message for a
failed connection will be shown in the display of the rotary
laser. For troubleshooting, consult the operating instruc-
tions for the rotary laser.
Direction indicators
The position of the laser beam in the reception area (1) is in-
dicated as follows:
– On the display (5) on the front and rear of the laser re-
ceiver by means of the "laser beam below centre line" dir-
ection indicator (f), the "laser beam above centre line"
direction indicator (j) and the centre line indicator (h)
– Optionally, by means of the red "laser beam below centre
line" LED direction indicator (4), the blue "laser beam
above centre line" LED direction indicator (2) and the
green centre 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 always sounds and the red
"laser beam below centre line" LED direction indicator (4)
and the blue "laser beam above centre line" LED direction
indicator (2) briefly light up (even if the audio signal and/or
LED direction indicators 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 centre
line" direction indicator (j) appears in the display.
If the LEDs are switched on, the blue "laser beam above
Bosch Power Tools
centre 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 direction of the ar-
row. When the laser beam is close to the centre line, only the
tip of the "laser beam above centre line" direction
indicator (j) is shown.
Laser receiver too high: If the laser beam hits the lower half
of the reception area (1), then the "laser beam below centre
line" direction indicator (f) appears in the display.
If the LEDs are switched on, the red "laser beam below
centre line" LED direction indicator (4) lights up.
If the audio signal is switched on, a signal sounds in a fast
rhythm.
Move the laser receiver downwards in the direction of the ar-
row. When the laser beam is close to the centre line, only the
tip of the "laser beam below centre line" direction
indicator (f) is shown.
Laser receiver centred: If the laser beam hits the reception
area (1) at the height of the centre line, then the centre line
indicator (h) appears in the display.
If the LEDs are switched on, the green centre line LED (3)
lights up.
If the audio signal is switched on, a continuous tone sounds.
Memory function of last reception: If the laser receiver is
moved so that the laser beam leaves the reception area (1)
again, the last displayed direction indicator for "laser beam
above centre line" (j) or "laser beam below centre line" (f)
flashes for a short time. This indicator can be switched on or
off via the settings menu.
Relative height indicator (see figure B)
If the laser beam hits the reception area (1), the clearance
between the laser beam and the centre line of the laser re-
ceiver is shown in the text display (e) as an absolute value.
The measuring unit for the height indicator can be changed
in the settings menu ("mm" or "in").

Display illumination

The displays (5) on the front and rear of the laser receiver
can be illuminated. The display illumination function is
switched on:
– When the laser receiver is switched on
– With each press of a button
– If the laser beam moves over the reception area (1).
The display illumination function automatically switches off:
– 30 s after each button press, if no laser beam reaches the
reception area
– 2 min after the last button press and if the position of the
laser beam in the reception area does not change.
The display illumination can be switched off in the settings
menu.
The setting for display illumination is not saved when the
laser receiver is switched off. After switching on the laser re-
ceiver, the display illumination is always switched on.
