BF TYPE 160 Series OPERATION MANUAL
Suction
Avoid aspirating solid matter or thick fluids; channel or valve
clogging can occur. If the suction valve clogs and suction
cannot be stopped, disconnect the suction tube from the
suction connector on the suction valve. Turn the suction
pump OFF.
During the procedure, take notice that the suction bottle does
not fill completely. Aspirating fluids into a full bottle may
cause the suction pump to malfunction.
Press the suction valve to aspirate excess fluid or other debris obscuring the
endoscopic image (see Figure 4.3).
Figure 4.3
Observation of the endoscopic image
Refer to the light source’s instruction manual for instructions on how to adjust the
brightness.
• For the BF-XP160F, the brightness setting on the video
system center is too high. Set the iris mode selection switch
on the video system center to peak iris mode. However,
when the image turns dark by using endo-therapy
accessories, set the iris mode selection switch to the average
iris mode.
• For adjusting the white balance of the BF-XP160F, set the iris
mode selection switch on the video system center to peak iris
mode. Otherwise, it may not be possible to correctly adjust
the white balance.
