Yamaha NAVIGO Owner's Manual page 6

Introduction
This is a manual for the "NAVIGO" electric power unit for wheelchairs. Before you read this manual, check
which product you are using.
This product consists of the left and right drive units, the joystick-equipped controller, the battery, optional
battery bag, the battery charger, and the optional assistant controller. These components, except for the
battery and charger, are already installed to the wheelchair frame. For the initial use, the customer does
not have to use tools, and so on, to assemble the wheelchair. Refer to "2. Names of Parts" to ensure that
these components are installed to the wheelchair that you purchased and that the battery and charger
are included. If you visually notice that any of these components are not installed, are not included, or are
damaged before using the wheelchair, immediately contact the dealer without using the wheelchair.
