8.0 MAINTENANCE AND PRODUCT CARE
8.0 Maintenance and Product Care
The SpeedCheck radar speed signs are designed to operate reliably for years with virtually no need for
maintenance. For solar models, Carmanah recommends routine inspections of the solar panels to ensure that
they are unobstructed by anything that may prevent effective solar charging, including:
•
Dirt and dust
•
Snow
•
Leaves
•
Debris
•
Shade that may have developed after installation due to adjacent plant growth.
The frequency of the inspections depends on location and local weather patterns. A yearly visual inspection of the
solar system is typically enough. The system is designed to be maintenance free, but maximum system
performance is achieved when the solar panels are clean. When inspecting the interior of the solar cabinet,
ensure the vents are clear and allow airflow. Confirm the green light on the charge controller indicates proper
solar charging. Refer to the solar charge controller manual for more detail.
8.1 Sign Inspection
Remove debris and soil from the face of the display and sign as you would with any road sign with a soft
microfiber cloth. Do not use oil-based solvents on the polycarbonate window or the sign face as this can cause
permanent fogging.
Check the mounting element hardware for tightness and confirm the pole interface hardware is secure.
Check the following items annually and more frequently in harsher environments:
1. Clean and check the radar and mount.
2. Clean both sides of the polycarbonate window. Use a microfiber cloth to minimize scratching.
3. Blow out the LEDs, cabinet, and internal components with compressed air. Ensure power is removed
prior to cleaning out the interior of the cabinet and display sign.
4. Visually inspect LEDs for alignment.
5. Visually inspect for corrosion or worn insulation.
As a preventative measure, if desired on legacy programmable boards, replace the two CR2032
coin cells for on-board clock backup (note positive battery contacts are closest to the outer edge
of the SpeedCheck controller PCBA.
