Product applicability
The following products are discussed in this article:
- SpeedCheck: SPEEDCHECK-12
Software required
- SpeedCheck Manager mobile app
The SPEEDCHECK-12 has built-in status LEDs that can be seen, from below, in the bottom right hand corner of the display. There are shields that direct the LEDs downwards so they can only be seen from an angle from below the sign and not directly on. In order to view the system LEDs, look up at them from below the viewing slot in the silkscreen.
The status LEDs are listed below when viewed from left to right on the display board:
- Power Status
- Vehicle Detection Status
- Radar Status
