Activating the Training Safety Shutdown
Before you demonstrate a Safety Shutdown for training purposes,
you must read about "Safety Shutdown" in the Getting Started
Manual, and watch the Safety Video. The purpose of demonstrating
Safety Shutdown for training purposes is to introduce the rider to the
experience while in a predictable, controlled environment with a
spotter. Read all the following steps prior to activating the Training
Safety Shutdown.
1. Make sure the Segway PT is in Balance Mode.
2. The rider should stand on the Mats with the Segway PT
remaining stationary.
3. The spotter should firmly hold the Segway PT, ready to keep it
steady and stationary when the Safety Shutdown begins.
4. A third person should hold the InfoKey Controller, and confirm
that both the rider and the spotter are ready.
