Inserting/Replacing the Battery

Alkali-manganese batteries are recommended for the measuring tool.
– Press the latch 9 of the battery lid outward and open the battery lid 11.
When inserting the battery, pay attention to the correct polarity according to the rep-
resentation on the inside of the battery compartment.
When the battery low indicator c appears for the first time on the display 7, the meas-
uring tool can still be operated for approx. 3 h.
 If the measuring tool is not used for a long period of time, the battery must be
removed. The battery can corrode or discharge itself over long periods.
Operation

Initial Operation

 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the measuring tool to adjust to the 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.
– Position the measuring tool at least 50 cm away from the rotational laser level. Po-
sition the measuring tool in such a manner that the laser beam can reach the recep-
tion area 6. Set the highest rotational speed on the rotational laser level.
Switching On and Off
 A loud audio signal sounds when switching on the measuring tool. "At a dis-
tance of 0.2 m, the A-weighted sound pressure level of the audio signal can be up
to 95 dB(A)."
 Do not hold the measuring tool close to your ear! The loud audio signal can
cause hearing defects.
To save energy, only switch the measuring tool on when you are using it.
– To switch on the measuring tool, press the On/Off button 1. Two audio signals
sound and all display indicators light up briefly.
– To switch off the measuring tool, press the On/Off button 1 again.
When no button is pressed on the measuring tool for approx. 10 minutes and when no la-
ser beam reaches the reception area 6 for 10 minutes, the measuring tool automatically
switches off in order to save the battery. The switching off is indicated by an audio signal.
