Operation
Charging the lithium-ion battery pack (accessory)
Note: The battery is supplied partially charged. To ensure full capacity of the battery,
completely charge the battery before the first use.
The USB port for connecting the USB cable (26) and the charging indicator light can be
found under the flap for the USB port (27) on the lithium-ion battery pack (24) (access-
ory). Open the flap for the USB port (27) and connect the USB cable (26).
During the charging process, the battery indicator on the display may differ from the ac-
tual state of charge of the lithium-ion battery pack (24). When the lithium-ion battery
pack (24) is fully charged, the charging indicator light will light up green.
During charging, the charging indicator light lights up yellow. A red charging indicator
light indicates that the charging voltage or charging current are unsuitable.
Start-Up
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be dazzled by the laser beam.
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always
u
carry out an accuracy check before continuing work if the measuring tool has been
subjected to severe external influences (see "Checking accuracy and calibrating the
grade measurement (see figure M)", page 51) and (see "checking accuracy of the
distance measurement", page 51).
The measuring tool is equipped with a wireless interface. Local operating restric-
u
tions, e.g. in aeroplanes or hospitals, must be observed.
Switching on/off
– To switch on the measuring tool and the laser, briefly press the measuring button (5)
[ ].
– To switch on the measuring tool without the laser, briefly press the on/off/back
button (8) [ ].
