It’s also just as easy to drive as before. As shown, the front panel carries a 3-digit LED display, a LED indicator and three pushbutton switches. Two of these pushbuttons let you set the alarm speed in 5km increments between 0km/h and 155km/h (one switch increases the speed; the other reduces it). As soon as you exceed the preset speed, the indicator LED lights and an internal piezo alarm briefly sounds at 10-second intervals to provide a warning
