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 R TC
battery and the integrated battery are weak. The
calibration interval will no longer be monitored.
– Contact an authorised service agent for Bosch
power tools.

Theft Alarm System

The system consisting of measuring tool and laser receiver
has two security mechanisms to help prevent theft:
– The measuring tool can only be operated using the laser re-
ceiver; there is no control panel on the measuring tool.
– Both audible and visual indications are given on the meas-
uring tool and on the laser receiver when the measuring
tool is moved away from the reference point.

Activating the Theft Alarm System

The default setting in the delivery condition is
[Theft alarm system deactivated].
– Press the theft alarm button 22 while the meas-
uring tool is switched on.
The theft alarm system is activated.
The theft alarm indicator 36 and the theft alarm
LED 4 light up.
The setting for the theft alarm system is saved when the tool
is switched off.
To deactivate, press the theft alarm button 22 while the
measuring tool is switched on.

If the theft alarm system is activated and the measuring tool
moves away from the current location for more than 5 s, the
alarm system will be triggered:
– An audio signal is emitted on the measuring tool and on the
laser receiver.
The A-weighted sound pressure level of the audio signal is
up to 110 dB(A) and cannot be adjusted using the volume
setting of the normal audio signal.

Indicators for Checking Calibration (Calibration
Warning)
If the calibration of the measuring tool has to be checked, this
is shown on the display of the laser receiver after switching on
by means of various indicators in combination with the "CAL"
indicator.
Note: The sensors for a calibration warning (calibration inter-
val, storage temperature, shocks to the measuring tool) are
active after the tool is started up for the first time.
