Attention!
Under no circumstances operate the measuring instrument
when opened. Leave no used batteries in the measuring instru-
ment, because even leak-proof batteries can corrode and there-
by release chemicals which can endanger health and destroy the
battery compartment. Used batteries do not belong with gene-
ral refuse. They are to be considered as requiring special hand-
ling and must hence be discarded without endangering the envi-
ronment.
