Bosch GLL 150 E Operating/Safety Instructions Manual page 14

The laser detectors have built in electronic
filtering for bright sunlight and electromagnetic
interference. Three distinct audio patterns
(high, on-grade, and low) assist targeting from
a distance.
The detector LR 3 has three speaker selections
(Off, Soft (~75 dB) and Loud (~85 dB)),
measured at 3 ft (1 meter).
This instrument is gasket sealed for water and dust protection. Use a soft, dry cloth to remove any
dirt or moisture from the instrument before storage. Do not use benzene, paint thinner, or other
solvents to clean the instrument. Remove battery before long-term storage of the instrument.
