If you feel the Segway HT slow down and shake its Handlebar, hear growling and beeping noises, and see the Display flash red, you should come to a stop and step off.

What is Safety Shutdown?

If the Segway HT detects a fault in any of its redundant subsystems (see the Reference Manual for a list), the Segway HT notifies you by automatically reducing its speed, shaking its Handlebar, making growling and beeping noises, and flashing red in the Display. This is called a Safety Shutdown.

How should I respond to Safety Shutdown?

You have approximately 10 seconds from the start of Safety Shutdown to come to a controlled stop and safely step off. After approximately 10 seconds, the Segway HT will stop balancing and you must have both feet off the Segway HT.

During a Safety Shutdown, the Segway HT may stop balancing and shut down immediately if you tilt it backward too steeply, and are stopped or moving slowly. Any time you encounter a Safety Shutdown, you should be prepared to step off as soon as you come to a stop.

If your Segway HT notifies you of a pending Empty Battery Condition, you should come to a controlled stop and safely step off of the Segway HT prior to commencement of the Safety Shutdown.

One of the conditions that can result in a Safety Shutdown is an empty battery condition. The Segway HT will notify you of a pending empty battery condition prior to initiating Safety Shutdown. A red unhappy face icon will appear in the Display, the Segway HT’s speed will be limited, and the Segway HT will beep.

Never restart and ride your Segway HT after it has indicated an empty battery condition or performed a low battery Safety Shutdown. The Segway HT may not have enough power to keep you balanced, especially if you demand a lot of power at once. If you restart and continue riding, you risk falling. Also, you may damage your Battery Packs resulting in reduced Battery Pack life and capacity.

DON’T try to force your Segway HT to perform a Safety Shutdown. Watch the Video Clip to become familiar with the sounds and motion of a Safety Shutdown.
