Assembly
The measuring tool can be operated either with a battery pack
13 or with AA batteries.
 Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and self-discharge.
Battery Charging (see figure C)
 Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lithi-
um-ion battery pack that can be used in your measuring tool.
Note: The battery supplied is partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion battery pack against deep discharging. When the battery
pack is discharged, the measuring tool is switched off by a
protective circuit.
 Following the automatic shut off of the measuring tool,
do not continue to press the On/Off button. The battery
can be damaged.
To remove the battery 13 press the unlocking buttons 12 and
pull the battery back and out of the measuring tool. Do not ex-
ert any force.
Observe the notes for disposal.

Inserting the battery

Note: Use of battery packs not suitable for the measuring tool
can lead to malfunctions of or cause damage to the measuring
tool.
Insert the charged battery 13 into the handle until you feel it
engage and it is flush with the handle.
Inserting/removing AA battery adapter
(see figure D)
 The AA battery adapter is only intended for the use in cer-
tain Bosch measuring tools and cannot be used with other
power tools.
Inserting AA battery adapter
Place the cover 17 into the slot 11. Place the batteries on the
sealing cap 16 as per the illustration. Next, slide the sealing
cap 16 over the batteries until you feel it engage and it is flush
with the handle.
Removing AA battery adapter
Press the unlocking buttons 12 of the sealing cap
16 and pull the sealing cap downwards to remove
it. Take care that the batteries do not fall out. Hold
the device with the battery compartment facing

Operation
 Protect the measuring tool against moisture and direct
sun light.
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the measuring tool to ad-
just to the ambient temperature before putting it into oper-
ation.
 Hold the measuring tool at the intended grip area 10
only, so as not to influence the measurement.
 Use or operation of transmitting systems, such as
WLAN, UMTS, radar, transmitter masts or microwaves,
in the close proximity can influence the measuring
function.
 The measuring values can be impaired through certain
ambient conditions. These include, e.g. the proximity
of devices that produce strong electric, magnetic or
electromagnetic fields, moisture, metallic building ma-
terials, foil-laminated insulation materials or conduc-
tive wallpaper or tiles. Therefore, also observe other in-
formation sources (e.g. construction plans) before
drilling, sawing or routing into walls, ceilings or floors.

Initial Operation

Switching On and Off
Check the measuring tool before each use. In the following
cases, safe function can no longer be ensured:
– The measuring indicator h constantly deflects, even
though you hold the tool in the air.
– The measuring indicator does not deflect, even though you
keep a finger in the sensor area.
– The device has visible damage or loose components inside
the measuring tool.
– Safe function is ensured only when one of the operating
mode selector buttons lights up.
 Before switching the measuring tool on, make sure that
the sensor area 14 is not moist. If required, dry the mea-
suring tool using a soft cloth.
 If the measuring tool was subject to an extreme tem-
perature change, allow it to adjust to the ambient tem-
perature before switching on.
To switch on the measuring tool, press the On/Off button 6
.
To switch off the measuring tool, press the On/Off button 6
again.
