4 Basic operation
●
In general, the [ANGLE] joystick of the control unit is manipulated with
the thumb of the hand holding the grip of the control unit.
●
Other buttons are also to be manipulated with the fingers of the hand
holding the grip of the control unit.
●
Hold the insertion tube with the other hand to which the control unit is
being held.
●
Increasing the insertion tube looping amount (bending amount) decreases the maximum angulation angle
limit of the angulation section. Keep the insertion tube as straight as possible to get the best operations
from the instrument.
●
Angulation tends to be difficult to achieve under low temperatures.
●
The image noise may be extreme under high ambient temperatures.
●
In case of RX, a yellow temperature indicator is displayed when ambient temperature is about 80 °C to
warn you that it is approaching the upper limit.
Note that this indicates that the upper limit of the ambient operating temperature is being approached.
●
Should the following message appears while inspecting with RX, immediately stop observation, carefully
withdraw the insertion tube, and perform the required action as instructed in "Error messages" (P. 71).
- HIGH TEMPERATURE (DISTAL END). PLEASE IMMEDIATELY PULL OUT THE INSERTION TUBE.
●
Do not bend the insertion tube to a radius that is less than its minimum bend radius (20 mm for the 4 mm
type, 30 mm for the 6 mm type) whenever operating the angulation section.
