Operating the control joystick: When engaging the main On/Off button, allow a few seconds prior to moving the joystick. This allows the system to self check. If you move the joystick too soon, the battery level indicator display will not illuminate until the joystick is released. If it is off centre for more than 5 seconds a system error will occur. Whilst this is not harmful to your wheelchair, you will need to switch off and then back on to clear the system.
Charging and programming socket: WARNING! This socket should only be used for programming and charging the wheelchair. WARNING! This socket should not be used as a power supply for any other device. Connection of other electrical devices may damage the control system or affect the EMC performance of the wheelchair See section 11 about charging.

10.11 The range of your vehicle Most manufacturers of mobility products state the range of their vehicles either in the sales literature or within the Owner’s Manual. The range stated sometimes differs from manufacturer to manufacturer even though the battery size is the same. Sunrise Medical measure the range of their vehicles in a consistent and uniform manner, but variances still occur due to motor efficiencies and overall product load weight. The range figures are calculated to I.S.O. Standard 7176.

A steeper (greater) angle within the preferred zone is desirable i.e. closer to, but never exceeding 75°. Restraint belts must not be held away from the body by wheelchair components or parts such as the armrests or wheels, (Fig 11.4).
11.4 Crash testing on the Hula. A representative Hula wheelchair has been tested in accordance with the dynamic performance requirements specified in ISO 7176-19:2001 “Wheeled Mobility Devices for use in Motor Vehicles” using an Unwins 4 point strap restraint system, (two at the front and two at the rear), that conforms to ISO 10542 or SAE J2249 and was used in accordance with the WTORS manufacturer’s instructions.
