• Ensure the light cable is correctly engaged with the
cable port.
• Ensure the L9000 is in Activate mode. (The
brightness level should appear on the LCD.)
If necessary, press the Activate/Standby toggle
button to switch from Standby to Activate. If the
unit remains in Standby:
1. Ensure the light cable is correctly engaged with
the cable port.
2. If an ESST cable is connected to the L9000,
ensure the cable is attached to the scope using
an ESST scope adapter.
• Use the up/down buttons to adjust the brightness. For
details, see the “Adjusting the Brightness” section in
this manual.
• Ensure the fiberoptic cable is transmitting light
properly. Hold the light-source end of the cable up to
an overhead room light and look into the scope end
of the light cable. If the pattern contains any black
spots, the light cable may be worn out and may
require replacement.
• Ensure the light cable is of an adequate size for the
application. The cable diameter may be too small to
provide adequate light transmission for the medical
video camera in the endoscopic application.
Excessive glare in

• Ensure the electronic shutter on the camera is
operating properly to control the video signal
brightness. If further light reduction is required,
decrease the light source brightness with the down
button.
