Attach ST2 Uni t to Firm Mounting Spot
- ST2 unit has approx. 40 cm (16″) of cable so it must be located near wires on motorcycle.
- The mounting spot for the ST2 unit should be flat and fairly horizontal.
- The ST2 device should be fixed to the handlebar, not the chassis or the rudder or any other part of the motorcycle.
- If necessary, use velcro or industrial double-sided tape (not included) to attach the unit.
- Mount the unit away from heat sources, such as the engine or exhaust.
How It Works? – User Manual
- ST2 recognizes and differentiates:
- Left or right turn
- Changing lane
- Roundabout
- Overtaking
- When you activate the left or right turn-signal lever, the turn-signal will start flashing.
- If you want to cancel the turn-signals, push the lever to the same side again.
- After each maneuver, ST2 cancels turn-signal automatically.
- ST2 recognizes when the vehicle is stationary and will not cancel the turn-signal.
- If you forget to cancel the turn-signal after the actual maneuver, the timer will cancel the turn-signal after 15 seconds of driving.
