Assembly
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the
measuring tool.
Remove the batteries from the measuring
tool when not using it for extended periods.
When storing for extended periods, the batteries
can corrode and discharge themselves.
Replace the battery as soon as the battery indicator
13 lights up.
Operation
Initial Operation
Protect the measuring tool against moisture
and direct sun irradiation.
Do not subject the measuring tool to
extreme temperatures or variations in tem-
perature. As an example, do not leave it in vehi-
cles for longer periods. 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 var-
iations in temperature, the accuracy of the measur-
ing tool can be impaired.
Switching On and Off
A loud audio signal sounds when switching
on the measuring tool. Therefore, keep the
measuring tool away from your ear or other
persons when switching on. The loud audio
signal can cause hearing defects.
