DR 600 radar for SpeedCheck

Product Applicability

This bulletin applies to the follow product lines:

  • SpeedCheck-15 radar speed signs
  • SpeedCheck-18 radar speed signs

Orders for new Speedcheck products or replacement radar kits starting Q3/Q4 2019 received the updated DR600 radar.


Prior to the release of the DR600 radar, Carmanah was using the DR500 in the SpeedCheck product line. With the release of the DR600, the DR500 ceased production and had gone end-of-life. The following are a few of the benefits with the DR600:

  • Considerable power savings (5x as efficient)
  • IP68 weatherproof enclosure (Carmanah did not use the IP65 version of the DR500)
  • Smaller footprint
  • Able to be mounted externally (inquire with Carmanah on this option)


No actions are required by the end user with regard to this technical bulletin. It is for informational purposes only.


  • The new DR600 radar is available as part of a drop-in replacement retrofit kit for the SpeedCheck-15/18 products.
  • The radar Carmanah uses is a custom model that is cabled specifically for use with SpeedCheck.
  • Contact Carmanah if you have an externally mounted radar application.
