5 Maintenance and Troubleshooting Tips
If help is needed during installation, operation, or configuration, contact the local FLIR representative, or
visit the FLIR Support Center at: https://support.flir.com/. FLIR Systems, Inc. offers a comprehensive
selection of training courses to help get the best performance and value from the thermal imaging
camera.

5.1 Cleaning
Great care should be used with your camera's optics. They are delicate and can be damaged by
improper cleaning. The camera's lens windows are designed for a harsh outdoor environment and are
coated for durability and anti-reflection. However, they can require occasional cleaning. If you are not
using an optional wash kit, FLIR suggests that you clean the lens windows when you notice image quality
degradation or excessive contaminant build-up on them.
Note
Do not disturb or move camera during cleaning.
Rinse the camera housing and optics with low pressure fresh water to remove any salt deposits and to
keep it clean. If the front window of the camera gets water spots, wipe it with a clean soft cotton cloth
dampened with fresh water.
Do not use abrasive materials, such as paper or scrub brushes, as this can damage the lens window by
scratching it. Only wipe the lens window clean when you can visually see contamination on the surface.
Use the following procedure and solvents, as required:
· Acetone – removal of grease
· Ethanol – removal of fingerprints and other contaminants
· Alcohol – final cleaning (before use)
1. Immerse lens tissue (optical grade) in Alcohol, Acetone, or Ethanol (reagent grade).
2. With a new tissue each time, wipe the lens window in an “S” motion (so that you do not wipe any area
more than once).
3. Repeat until the lens window is clean. Use a new tissue each time.
Caution
The DX-608 camera model does not have a silicon window protecting its germanium thermal camera
lens.
5.2 Troubleshooting
No Video
If the camera will not produce an image, check the connections at the camera and at the display. If the
connectors appear to be properly connected but the camera still does not produce an image, ensure that
power has been properly applied to the camera and the circuit breaker is set properly. If a fuse was used,
be sure the fuse is not blown.
If the camera still does not produce an image, contact the FLIR dealer or reseller who provided the
camera, or contact FLIR directly.
