Bosch GLM 30 Instrucciones De Funcionamiento página 10

A) The working range increases depending on how well the laser light is
reflected from the surface of the target (scattered, not reflective) and with
increased brightness of the laser point to the ambient light intensity (interior
spaces, twilight). In unfavorable conditions, e.g., with extreme illumination
or a badly reflecting surface, the measuring range may be limited.
B) In favorable conditions, a deviation influence of ±0.05 mm/m must
be taken into account. In unfavorable conditions, e.g., with extreme
illumination, badly reflecting surface or the room temperature deviating
heavily from 77 °F (25 °C), the maximum deviation can be up to ±3.0mm.
Additionally, a deviation influence of 0.15mm/m must be taken into account
C) Battery compartment not included.
The measuring tool can be clearly identified with the serial number 9 on
the type plate.
Preparation
Inserting/Replacing the Batteries
AAA Alkaline batteries are recommended for the measuring tool.
To open the battery lid 7, press the latch 8 and remove the
battery lid. Insert the batteries. When inserting, pay attention to
the correct polarity according to the representation on the inside
of the battery compartment.
When the battery symbol appears for the first time on the
display, there is approximately 15 minutes of useage remaining
while in real time measurement mode. When the battery symbol
flashes, the batteries must be replaced; measurements are no
longer possible.
Always replace all batteries at the same time. Only use
batteries from one brand and with identical capacity.
Remove the batteries from the tool when not using it for
extended periods. When storing for extended periods, the
batteries can corrode and discharge themselves.
