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 8, turn the locking knob 9

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 batteries/

rechargeable batteries together.
Shut the battery compartment 8 and turn the locking knob 9

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 7 before using for the first time. The

battery pack can only be charged with the battery charger 15

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 16 for your mains supply in-

to the battery charger 15 and allow it to engage.
Insert the charge plug 17 of the battery charger into the sock-

et connector 11 of the battery pack. Connect the battery
