Description
General This manual applies to Zoom 20 and Zoom 30 instru-
ments. Where there are differences between the
instruments they are clearly described.
Telescope • Measuring with IR modes: When measuring
distances to a reflector with Electronic Distance
Measurement (EDM) mode "IR", the telescope uses
a wide visible red laser beam, which emerges
coaxially from the telescope's objective.
• Measuring with RL modes: Instruments that are
equipped with a reflectorless EDM additionally offer
the EDM mode "Refelectorless (RL)". When meau-
ring distances with this EDM mode, the telescope
uses a narrow visible red laser beam, which
emerges coaxially from the telescope's objective.
