Basic operation
4.1
Viewing an observation object
1
Turn on the light.
Touch the [LIGHT] button on the live screen.
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.
The angle of the angulation section stays in place after you have released your finger from the
joystick.
4
While watching the display screen, carefully withdraw the insertion tube.
Make sure to restore the joystick to the neutral position before pulling out 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. 37).
-
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 (30 mm).
•
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
•
To hide the buttons displayed on the screen, touch any area on the screen other than the buttons.
To display the buttons, touch the screen again. (The buttons appear for approximately 3 seconds.)
•
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.
•
When the operating temperature of the distal end reaches about 70ºC, a yellow-colored temperature
indicator is displayed. Take precautions as this indicates that the temperature is close to the maximum
operating limit.
