To open the battery lid, placed under the instrument, slide the
stopper in the direction of the arrow and overturn the battery lid,
and then insert the battery.
When inserting, pay attention to the correct polarity, positive po-
larity toward inside, negative polarity toward outside. When the
battery becomes weak, the battery low indicator continuously
flashes red, the measuring tool can be operated for less than 2H.
Take out weak battery, insert the battery into the adapter to
recharge it. When battery charging is terminated, the indicator
changes from red to green.
OPERATION
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not expose the measuring tool to extreme temperatures or
variations in temperature.
Do not leave it in vehicles for longer periods.
In case of significant variations in temperature, allow the me-
asuring tool to adapt to ambient temperature before putting it
into operation.
In case of extreme temperatures or variations in temperature, the
accuracy of the measuring tool can be impaired.
Avoid heavy impact or falling of the measuring tool. After an he-
avy impact on the measuring tool, an accuracy check should
always be carried out before continuing to work.
Switch the measuring tool off during transport.
When switching off the leveling unit is locked in order to avoid
damage during transport.
SWITCHING ON AND OFF
To turn on the measuring tool, slide the On/Off switch to the
position (when working without automatic leveling) or to the
position (when working with automatic leveling).
Immediately after switching it on, the measuring tool issues an
horizontal laser plane by the exist openings.
To turn on or off the horizontal beam press “H” button. To turn on
or off the vertical beam, press “V” button.
Do not point the laser beam at person or animal and do not look
into the laser beam yourself, not even from far away.
To switch off the measuring tool, slide the On/Off switch to the
“off” position, when switch off, the leveling unit is locked.
When the maximum internal operating temperature of 45° C is
exceeded, the measuring tool switches off to protect the laser diode.
After cooling down, the measuring tool is ready for operation and
can be switched on again.
AUTOMATIC LEVELING
Operation with Automatic Leveling
Position the measuring tool on a plane and firm support, or mount
it to the tripod. To operate with automatic leveling push the on/
off switch to position. After switching on, the leveling function
automatically compensates irregularities within the self-leveling
