3.1.4 Scanplane Rotation Operation
CAUTION
●
Do not use excessive force on the scanplane rotation control wheel at its outer
positions as this may damage the gastroscope mechanism.
●
The transducer scan plane can be rotated from 0° (transversal plane) via 90°
(longitudinal plane) to 180° (transversal plane, left/right inverted). All planes in
between can also be chosen. This makes it possible to scan a conical imaging
volume.
