4 Basic operation
4.1 Viewing an observation object
WARNING
• The distal end will be hot immediately after use in a high-temperature environment. Do not touch it directly.
Doing so creates the risk of burn injury.
1
Turn on optical adapter illumination.
2
While watching the display screen, insert the insertion tube into the
observation object.
Insert carefully while checking the insertion direction.
3
Use the joystick to perform angulation operations and observe the applicable
locations on the display.
Be careful not to apply excessive pushing force, twisting or tension to the insertion tube.
4
Lock the angulation section angle and direction (angulation lock) and perform
observation.
When the angulation section is at the desired angle and direction, rotate the angulation lock
ring to align the "L" and "-" marks. Fine adjustment of the angulation angle can be performed
while angulation is locked.
5
While watching the display screen, carefully withdraw the insertion tube.
If angulation is locked, first rotate the angulation lock ring to align the "F" and "-" marks to
unlock it before removing the insertion tube.
CAUTION
• Should any of the following messages appear during observation, immediately stop observation, carefully
withdraw the insertion tube, and perform the required actions as instructed in "Error messages" (P. 36).
- OVER CURRENT (ADAPTER). PLEASE TURN OFF THE POWER AND CLEAN THE ELECTRODE.
- HIGH TEMPERATURE (DISTAL END). PLEASE IMMEDIATELY PULL OUT THE INSERTION TUBE.
• Should you sense any abnormality, do not try to force the operation and carefully withdraw the insertion
tube. Note the following precautions when withdrawing the insertion tube.
- Do not try to withdraw from the observation object while angulation is locked or while the angulation
section is bent.
- If the insertion tube becomes caught on something during withdrawal, rotate the control unit gently while
continuing the withdrawal.
• A yellow temperature indicator will appear on the display if the ambient operating temperature of the distal
end reaches approximately 80°C. Note that this indicates that the upper limit of the ambient operating
temperature is being approached.
• The battery indicator flashes yellow if the battery overheats. Note that this indicates that the upper limit of
the operating temperature is being approached.
NOTE
• 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 LCD monitor may not display data normally when the instrument is used in an environment where
temperatures are below 0°C. Use a heater to warm the area before operation. The amount of screen noise
may increase under high ambient temperatures.
