16 LTL-XL Retroreflectometer DELTA
Lower icon row
• From the lower icon row you can select a road marking icon that will be saved together
with the measurement in the log. Access the icons by pressing the DOWN button ▼. Use
the LEFT or RIGHT button to mark the preferred icon. Pressing DOWN again shows more
icon rows from a roll stack of four rows. One row, marked with a "PR" for "Preset" can
be preset by the user (see pg. 30) and is saved separately for each measuring series. It will
be the active icon row, ready for selection, when a measuring series is selected.
• Activate the marked icon with the OK button or exit with the HOME or UP ▲ button.
The selected icon is now shown in the left side of the HOME screen and the instrument
is again ready for measuring.
• Other functionality regarding the lower icon row:
Activating an already selected icon will cancel the activation and remove the icon from
the main display (and no icon will be saved by the next measurement).
