Image quality is
otherwise poor. Various • Verify that the QuickChange probe is properly seated and latched. See “To Install a
Probe” on page30.
• Clean the optical tip and camera head. See “To Inspect and Clean an Optical Tip” on
page111 and “To Inspect and Clean a Probe” on page 112.

listed specifications. For an illustration of the battery charge indicators, see “Maintaining
the Battery” on page118.

Various • Verify that the probe is properly seated and latched. See “To Install a Probe” on
page30.
• Point the probe tip toward a bright light and see if image appears. If image appears, the
problem is associated with lamp operation. If still no image, contact GE Inspection
Technologies.
• If an external monitor is available, determine whether an image appears on it. Connect
the monitor’s VIDEO IN (or S-VIDEO IN) to the base unit’s VIDEO OUT (or S-VIDEO
OUT) connector. Verify the image.
Frozen image “jitters.” Probe tip was moving
when image was
captured.
Unfreeze then refreeze the image, keeping probe tip steady.
