Set the brightness of the light source to the minimum
necessary to perform the procedure safely. If the endoscope
is used for a prolonged period at or near maximum light
intensity, vapor like smoke may be observed in the
endoscopic image. This is caused by the evaporation of
organic material (remaining blood, moisture of stool and so
on) due to heat generated by the light guide near the light
guide lens. If this vapor continues to interfere with the
examination, remove the endoscope, wipe the distal end of
the endoscope with a lint-free cloth moistened with 70% ethyl
or isopropyl alcohol, reinsert the endoscope and continue the
examination.
The control section of the endoscope is designed to be held in the left hand.
The air/water and suction valves can be operated using the left index finger. The
UP/DOWN angulation control knob and the elevator control lever can be
operated using the left thumb. The right hand is free to manipulate the insertion
tube and the RIGHT/LEFT angulation control knob (see Figure 4.1).
