PROTEC CS-550M Smart Alarm Theft Alarm System for 12v Motorcycles Simple operation: just turn the key ON/OFF. No need to carry a remote control, and no worries about the remote control battery dying. ◆ No remote control needed! ◆ Set and disarm with only your motorcycle key! 【Shape Memory System】 ・ Uses a digital 3G sensor that memorizes the current state of the motorcycle in 3 dimensions: X-axis, Y-axis, and Z-axis! ・ If the motorcycle is moved even slightly, a warning/alarm sound will be emitted. ・ Even after the alarm sound stops, the 3G sensor will re-memorize the motorcycle's state and maintain the alarm standby state! I had this installed on my current Eliminator 400. I am selling it because I am changing motorcycles. Purchased around June 2024, removed in November and stored indoors. Please check the manual and installation instructions on the website.
