Bosch T / 229 Notice Originale page 15

Do not attach any stickers or labels to the sensor
u
area (14) on the rear of the measuring tool. Metal la-
bels in particular will affect measuring results.
Do not wear gloves when taking measure-
ments and make sure that you are properly
earthed. If you are not properly earthed, the
material identification of "live" wires may be im-
paired.
When taking measurements, avoid devices
that emit strong electric, magnetic or elec-
tromagnetic fields. If possible, deactivate all
tools whose radiation could interfere with the
measurement and switch off the corresponding
functions or tools.
Measuring Tool Power Supply
The measuring tool can be operated either with conventional
non-rechargeable batteries or with a Bosch lithium-ion bat-
tery.
Operation with rechargeable battery pack (see figure B)
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your measuring tool.
Note: The use of batteries unsuitable for your measuring tool
can lead to malfunctions or damage to the measuring tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". A protective circuit
switches the measuring tool off when the battery is drained.
To insert the charged battery pack (7), slide it into the bat-
tery bay (17) until you feel it engage.
To remove the battery pack (7), press the release buttons
(6) and pull the battery pack out of the battery bay (17). Do
not use force to do this.
Operation with non-rechargeable batteries (see figure C)
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
The batteries are inserted into the battery adapter.
The battery adapter is intended only for use in desig-
u
nated Bosch measuring tools and must not be used
with power tools.
To insert the batteries, slide the receptacle (16) of the bat-
tery adapter into the battery bay (17). Place the batteries in
the receptacle as shown in the picture on the cap (15). Slide
the cap over the receptacle until you feel it click into place.
Bosch Power Tools
To remove the batteries (18), press the re-
lease buttons (6) of the cap (15) and pull off
the cap. Make sure that the batteries do not fall
out by holding the measuring tool with the bat-
tery bay (17) facing upwards. Remove the bat-
teries. To remove the receptacle (16) from in-
side the battery bay, reach into the receptacle
and pull it out of the measuring tool, applying light pressure
to the side wall as you do so.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Starting Operation
Switching on/off
Before switching on the measuring tool, ensure that
u
the sensor area (14) is dry. If necessary, use a cloth to
dry the measuring tool.
If the measuring tool has been exposed to a significant
u
change in temperature, leave it to adjust to the ambi-
ent temperature before switching it on.
To switch on the measuring tool, press the on/off
button (8).
To switch off the measuring tool, press the on/off
button (8) again.
If no button on the measuring tool is pressed for approx.
5 minutes, the measuring tool will automatically switch itself
off to preserve battery life.
Check the measuring tool before each use. Safe operation
cannot be guaranteed in the following circumstances:
– The measuring tool has visible damage or there are loose
components inside the measuring tool.
– The measuring indicator (e) constantly deflects, even
when holding the measuring tool in the air.
– The measuring indicator (e) does not deflect at all, even
when holding a finger in the sensor area.
– None of the operating mode buttons light up.
Switching audio signal on/off
The audio signal can be switched on/off with the audio signal
button (4). When the audio signal is switched off, the audio
signal indicator (i) appears on the display.
Operating Modes
Once it has been switched on, the measuring tool defaults to
the universal operating mode.
To change the operating mode, press the button for the re-
quired operating mode (button for universal operating
mode (9), button for concrete operating mode (3) or button
for drywall operating mode (10)). The selected operating
mode is indicated by the illuminated button.
