3. Refer to the display unit's Instructions
for Use for a detailed troubleshooting
guide or use a different endoscope.
Replace the endoscope with a new one.
Return to a live image by pressing
the blue live image tab or restart the
display unit by pressing the power
button for at least 2 seconds. When
the display unit is off, restart it by
pressing the power button again.
Gently rub the distal tip against the
mucosa. If the lens cannot be cleaned
this way, remove the endoscope and
wipe the lens with sterile gauze.
Clean the working channel using
a cleaning brush or flush the working
channel with sterile saline using
a syringe. Do not operate the suction
button when instilling fluids.
Make sure that the suction tube is
properly connected to the endoscope
and to the suction system. Make sure
that the suction system is turned on.
Remove the endotherapy instrument or
introducer/syringe from the working
channel port/biopsy valve. Check that
the instrument used is compatible with
the working channel's ID.
Make sure that the cap is attached
to the biopsy valve to avoid
reduction of suction capability.
Make sure that the endotherapy
instrument and working channel size
are compatible.
When the cap of the biopsy valve is
detached, it may be easier to insert an
endotherapy instrument into the
instrument channel port.
