  • At a 45 degree angle to the flow of traffic.

  • Where the far side lane is no greater than 50 feet away.

  • Where traffic is free flowing.


What do the lights on the front of the Black Cat Radar mean?

  • Alarm Indicator – This light illuminates during boot-up. It also illuminates when a fault is detected. Wait for this light to go off before attempting to connect to the STARnext software.

  • Run/Vehicle Indicator – This is normally ON, and flashes off when a vehicle is detected.

  • Busy Indicator – This light alone, or in conjunction with the Alarm light, indicates the unit is conducting a firmware update.

  • USB Indicator – This indicates that the Black Cat is connected to a computer using the Mini USB port


The lights may time out after approximately 1 minute. Simply push the Wake button to again see the lights.
