• The operational display appears automatically aer the start-up procedure. Only then
can a measurement operation commence.
• During initial commissioning, function 060 "language" and function 083 "distance unit"
appear once only. Aerwards, the measured value display appears.
• The default values are always shown in bold in the following chapters, unless they are
explicitly mentioned.

Symbol Meaning
This lock symbol is displayed when the measuring device is locked and no entries
can be made.
This alarm symbol is shown when the device is in an alarm condition (error
condition). A ashing symbol indicates that a fault has occurred.
This symbol ashes when the device is in the "manual" measurement mode.
When the button is pressed, the symbol disappears and the direction selected
(run up ↑ run down ↓) is shown.
