Sign Refresh | Sign Upgrade

If you experiencing a problem with your sign please refer to the Troubleshooting Guide first to diagnose any issues and resolve them prior to requesting a return. Often times it is a simple programming, installation, or maintenance issue, not a sign operation issue, that is preventing the sign from operating properly.

If you are not successful in troubleshooting the issue you are having with your radar speed sign, please call Customer Support at 678-965-4814 and one of our team members will be happy to assist you.


The “standard of care” for signs more than two years old that are not under warranty is to provide an electronics overhaul, or refresh.

A refresh* of your sign includes:

  • Replacement of CPU board, radar interface board, and radar component
  • Two new 18 amp/hour batteries for solar models that use them
  • Replacement of Bluetooth transmitter with Wi-Fi transmitter
  • Upgrade of sign code to the latest version
  • Return ground shipping
  • New 1 year warranty on entire sign

*The refresh of the sign does not cover any housing repair.


The cost to refresh a sign is listed below and varies by the size of the sign and how the sign is powered (AC/solar/battery). To determine what model sign you have, look at the serial number label on the sign housing.

Each sign serial number begins with SNTC followed by the model number and 6 digits. The first digit indicates the sign model number.

If you would like to return your sign for a refresh, please submit a Sign Return Request form at the bottom of this page. You will need to provide your 6 digit sign serial number for your request.

A Radarsign customer service representative will review your request and will contact you within 2 business days.
