Operation with Batteries/Rechargeable Batteries
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
To open the battery compartment 14, turn the locking knob
15 to position and pull out the battery compartment.
When inserting the batteries/rechargeable batteries, pay at-
tention to the correct polarity according to the representation
on the inside of the battery compartment.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
Shut the battery compartment 14 and turn the locking knob
15 to the position.
In case the batteries/rechargeable batteries have been insert-
ed incorrectly, the measuring tool cannot be switched on. In-
sert the batteries/rechargeable batteries with correct polarity.
f
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 discharge themselves.
Operation with Battery Pack
Charge the battery pack 13 before using for the first time. The
battery pack can only be charged with the battery charger 22
intended for it.
f
Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the battery charger.
Insert the appropriate mains plug 23 for your mains supply
into the battery charger 22 and allow it to engage.
Insert the charge plug 24 of the battery charger into the
socket connector 17 of the battery pack. Connect the battery
charger to the mains supply. Charging the empty battery pack
takes approx. 14 h. The battery charger and the battery pack
are protected against overcharging.
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
Do not charge the battery pack 13 each time after using, oth-
erwise its capacity will be reduced. Charge the battery pack
only when the charge-control indicator 12 flashes or lights up
continuously.
A considerably reduced operating period after charging indi-
cates that the battery pack is used up and must be replaced.
If the battery pack is empty, the measuring tool can also be
operated off of the battery charger 22 when connected to a
power supply. Switch the measuring tool off, charge the bat-
tery pack for approx. 10 min and then switch the measuring
tool on again with the battery charger connected.
To change the battery pack 13, turn the locking knob 16 to
position and pull out the battery pack 13.
Insert a new battery pack and turn the locking knob 16 to the
position.
f Remove the battery pack from the measuring tool
when not using it for longer periods. When storing for
longer periods, the rechargeable batteries can corrode
and discharge themselves.
Charge-control Indicator
When the charge-control indicator 12 flashes red for the first
time, the measuring tool can still be operated for approx. 2 h.
When the charge-control indicator 12 lights up red continu-
ously, measurements are no longer possible. The measuring
tool switches off automatically after 1 minute.
Power Supply of the Remote Control
Using alkali-manganese batteries is recommended for opera-
tion of the remote control.
To open the battery lid 34, press the latch 33 in the direction
of the arrow and remove the battery lid. Insert the battery pro-
vided. When inserting, pay attention to the correct polarity
according to the representation on the inside of the battery
compartment.
f
Remove the battery from the remote control when not
using it for longer periods. When storing for longer peri-
ods, the battery can corrode and discharge itself.
