Switching On and Off

 Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
 Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
Note: Before using the measuring tool, you should always
perform an accuracy check (see "Accuracy Check of the
Measuring Tool", page 42).

Initial Operation

Note: In their delivery condition, the measuring tool and laser
receiver are paired (= laser receiver can perform the remote
control functions).
To save energy, only switch the measuring tool and the laser
receiver on when you are using them.

Switching On

– To switch on the measuring tool, slide the laser
receiver into the charging/storage station 6 and
then press the On/Off button 17.
or
– Slide the laser receiver into the charging/storage
station 6 and remove it from the charging/stor-
age station again. To switch on the measuring
tool, you then have to press the On/Off button
17 within 30 minutes.
Outcome
– All display indicators light up briefly.
– Automatic levelling starts (see "Automatic Levelling",
page 39).
– The anti-drift system is activated 30 s after automatic lev-
elling (see "Anti-Drift System (ADS)", page 40).
The measuring tool then emits the laser beam 7 (GRL 500 H)
or the laser beam 7 and the plumb beam 1 (GRL 500 HV).

Switching Off

– Press the On/Off button 17 for approx. 2 s.
Outcome
– The rotation stops and the laser beam is switched off.
– All display indicators and the display illumination are
switched off.
Note: If the laser receiver and the rotational laser level are
switched off, the laser receiver first has to be docked back in
the charging/storage station 6 to switch the tool on.

Sleep Mode

The laser receiver can be used to put the measuring tool into
sleep mode for maximum 2 hours.
– To switch on sleep mode, press the sleep mode
button 21.
Bosch Power Tools
In sleep mode, the sleep mode indicator 44 on the
laser receiver lights up and the theft alarm indicator
36 also lights up if the theft alarm system is activat-
ed.
The theft alarm LED 4 on the measuring tool flashes
if the theft alarm system is activated.
All other indicators and the laser beam are
switched off. The anti-drift system remains activat-
ed.
– To end sleep mode, press the sleep mode button
21 again.
Sleep mode is automatically switched on if the laser beam
does not run through the reception area 26 for more than
30 minutes or the buttons on the laser receiver are not
pressed for more than 30 minutes.
Note: If the laser receiver and the rotational laser level are in
sleep mode for more than 2 h, both are automatically
switched off. The laser receiver first has to be docked back in
the charging/storage station 6 to switch the tool on.

Automatic Shutdown

The measuring tool and the laser receiver switch off automat-
ically under certain conditions (see "Switching Off", page 37
for outcome):
– The measuring tool does not receive any commands for
more than 2 h.
– The buttons on the laser receiver are not pressed for more
than 2 h.
– The measuring tool is outside of the self-levelling range for
more than 2 h.
– The measuring tool is not switched on again within 2 h
when sleep mode is activated.
– The anti-drift system is triggered for more than 2 h.
– The measuring tool is outside of the operating temperature
range.
Before the measuring tool and laser receiver auto-
matically switch off, an audio signal sounds and the
out-of-temperature-range indicator 34 flashes for
approx. 5 s.
After automatic shutdown:
– If applicable, wait until the measuring tool and the laser re-
ceiver are back in the operating temperature range.
– If required, reposition the measuring tool and switch it on
again.

RTC (Real Time Clock) Battery

If the calibration interval indicator 35 flashes for
approx. 10 s after the tool is switched on, the RTC
battery is weak. The calibration interval will no
longer be monitored.
