MAINTENANCE

Clean the enclosure window periodically with a mild non-abrasive detergent in water and a soft cloth to help maintain picture clarity.

If operating problems are experienced with the system, refer to the Troubleshooting section.

The pan and tilt is IP 66 and NEMA 4X rated. The pan and tilt left side cover must be removed to gain access to the DIP switches. When the cover

is correctly reinstalled, the rating will remain in effect.

If the window wiper assembly is installed, replace worn or deteriorated wiper blades immediately. At a minimum, replace wiper blade once a

year.

To order replacement wiper blades or if further maintenance is required, contact Pelco’s Customer Service Department for assistance. Refer to

the Product Warranty and Return Information section.
